    SUMMARY*
    Medical Law
    The panel affirmed the district court’s dismissal of a
    complaint brought by patients who suffered no injuries but
    who were subject to the off-label use of a medical device for
    eye surgeries, where the Food and Drug Administration status
    of the device was not disclosed to the patients.
    The panel held that the complaint did not state a claim
    under the California Protection of Human Subjects in Medical
    Experimentation Act because the surgeries were not “medical
    experiments” subject to the protection of the Act. The panel
    also held that plaintiff Robert Perez did not have standing to

    sue for injunctive relief under the California Consumers
    Legal Remedies Act, and his other substantive claim—a
    common law fraud by omission claim—was preempted by the
    Federal Food, Drug, and Cosmetic Act. The panel held that
    the claim of omission was expressly preempted by the
    preemption provision in the Medical Device Amendments;
    and even if it were not, it was impliedly preempted because
    it amounted to an attempt to privately enforce the Food, Drug
    and Cosmetic Act.

    OPINION
    McKEOWN, Circuit Judge:
    We are asked to decide whether patients who suffered no
    injuries but who were subject to the off-label use of a medical
    device for eye surgeries may bring suit solely because the
    Food and Drug Administration (“FDA”) status of the device
    was not disclosed to them. The Third Amended Complaint
    (“the Complaint”) does not state a claim under the California
    Protection of Human Subjects in Medical Experimentation
    Act (“the Human Subjects Act”) because the surgeries were
    not “medical experiments” subject to the protection of the
    PEREZ V . NIDEK CO ., LTD .                        5
    Act. Robert Perez does not have standing to sue for
    injunctive relief under the California Consumers Legal
    Remedies Act (“CLRA”), and his other substantive claim is
    preempted by the Federal Food, Drug, and Cosmetic Act
    (“FDCA”). We affirm the district court’s dismissal of the
    Complaint.
    BACKGROUND 1
    Robert Perez, Nancy Art, and Brett Harbach (collectively,
    “Perez”) each sought and received Laser in Situ
    Keratomileusis (“LASIK”) eye surgery with a Nidek EC-
    5000 Excimer Laser System (“the Laser”) to correct
    farsightedness. They claim that, at the time of their surgeries,
    they did not know the FDA had not approved the Laser for
    this use. According to the Complaint, had they known, they
    would not have consented to the surgeries.
    Perez sued on behalf of himself and a class of similarly
    situated individuals who received hyperopic surgery (surgery
    to correct farsightedness) with the Laser between February
    1996 and October 2006. Perez does not allege any injury
    stemming from surgery. Nor does Perez claim that his or any
    other surgery was ineffective. Instead, he asserts claims
    under the Human Subjects Act and the CLRA, as well as
    common-law claims of fraud by omission, civil conspiracy,
    and aiding and abetting. Perez brought these claims against
    various Nidek corporate entities (“Nidek”), named and
    unnamed physicians who allegedly used the Laser for
    unapproved purposes on individuals in the purported class
    1
    This background is taken from the factual allegations in the Complaint,
    which we treat as true for purposes of evaluating the motion to dismiss.
    See Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678 (2009).
    6                PEREZ V . NIDEK CO ., LTD .
    (“Physician Defendants”), named and unnamed medical
    centers where these procedures were allegedly performed,
    and other unnamed persons and entities who allegedly
    participated in the conduct at issue. Of the named Physician
    Defendants, only two performed LASIK surgery on the
    named plaintiffs.
    The Laser is a Class III medical device under the FDCA,
    as amended by the Medical Device Amendments of 1976
    (“MDA”). 21 U.S.C. § 360c. For that reason, Nidek was
    required to get premarket approval (“PMA”) from the FDA
    before it could sell or distribute the Laser. 21 U.S.C. § 360e.
    Between 1998 and 2000, Nidek obtained three PMAs for
    treating nearsightedness with the Laser, but the Laser was not
    approved for treating farsightedness until October 2006. The
    PMAs restricted the Laser from being used for hyperopic
    corrections outside of approved investigations. During the
    class period, use of the Laser for farsightedness was being
    investigated in FDA-approved clinical trials, which required
    full disclosure of the device’s experimental use and informed
    consent from patients receiving treatment.
    Perez alleges that the defendants engaged in a nationwide
    scheme to modify the approved Laser to enable it to correct
    farsightedness before it was approved for that purpose. He
    claims that Physician Defendants used the modified Lasers to
    perform hyperopic surgeries without informing patients that
    the Laser was not approved for that use outside of approved
    clinical trials, and that Nidek knew about the improper use of
    the Laser. Perez further alleges that the defendants conspired
    and aided and abetted each other in their unlawful conduct.
    The FDA was aware of claims that the Laser was being
    put to unauthorized uses, and it took steps to halt abuses. In
    PEREZ V . NIDEK CO ., LTD .                 7
    late 2000, the FDA sent Nidek a letter expressing concern
    that chips in Laser units were being replaced with chips that
    enable the device for “unapproved applications, such as
    hyperopia.” The letter addressed allegations that Nidek
    employees were providing the replacement chips and that
    Nidek had fired at least one employee for doing so. It also
    noted that Nidek had waited several months after becoming
    aware that some Lasers had been tampered with before
    reporting the problem, in violation of the PMA conditions.
    In 2001, the FDA sent two sets of warning letters to
    certain physicians after an investigator determined that the
    Lasers they were using for hyperopia were manufactured
    before Nidek’s PMA was effective and that the Lasers
    contained software not approved for commercial distribution
    in the United States. The first letter stated, “Because an
    approved PMA or an approved IDE [Investigational Device
    Exemption] does not cover this laser, it is adulterated within
    the meaning of the Act. Therefore, you should not be using
    this laser to treat patients.” The second letter reiterated the
    information in the first letter and added that the modified
    lasers needed to be certified as in compliance with the federal
    laser product performance standard. In addition, the FDA
    published an Import Alert addressing the problem of Lasers
    with software not approved under the PMAs.
    Perez alleges that, “[d]espite these actions by [the] FDA,
    Defendants continued to sell, distribute, lease, use, service,
    and market the Lasers in the United States with the capacity
    to perform hyperopic procedures.” He alleges that Nidek
    “continued to install, service and enable the Lasers to perform
    hyperopic corrections outside of sanctioned clinical trials”
    and that Nidek falsified many service records indicating that
    it had removed the software. In October 2006, the Laser was
    8                    PEREZ V . NIDEK CO ., LTD .
    approved for hyperopic use with improved and updated
    software and treatment parameters.
    ANALYSIS
    I. STANDING
    Perez sued two groups of doctors: the two doctors who
    performed surgery on the named plaintiffs, and named and
    unnamed doctors who performed no surgery on the named
    plaintiffs, but who allegedly performed surgery on other
    individuals in the proposed class. With respect to the first
    group, standing is not at issue, but the second group raises a
    serious standing question.2 See Easter v. Am. W. Fin.,
    
    381 F.3d 948
    , 961–62 (9th Cir. 2004) (holding that borrowers
    of second mortgage loans had no standing to sue those
    investment trusts that did not hold a named plaintiff’s note
    because they could not trace the alleged injury in fact to those
    defendants’ actions).
    Perez apparently endeavors to sidestep the traceability
    hurdle for the second group of doctors through his allegations
    of conspiracy and aiding and abetting. A look at those
    allegations reveals virtually nothing because they are no more
    than conclusory and bare bones words and phrases without
    any factual content. Such vacuous claims are insufficient to
    establish standing or to survive a motion to dismiss. See
    Lujan, 504 U.S at 561 (explaining that the elements of
    standing “must be supported in the same way as any other
    2
    Although Perez, as the party invoking federal jurisdiction, has the
    burden of establishing Article III standing, Lujan v. Defenders of Wildlife,
    
    504 U.S. 555
    , 561 (1992), he did not respond to the argument that he had
    no standing to sue the second group of doctors.
    PEREZ V . NIDEK CO ., LTD .                  9
    matter on which the plaintiff bears the burden of proof, i.e.,
    with the manner and degree of evidence required at the
    successive stages of the litigation”); Iqbal, 
    556 U.S. at 678
    (“To survive a motion to dismiss, a complaint must contain
    sufficient factual matter, accepted as true, to ‘state a claim to
    relief that is plausible on its face.’” (citation omitted)).
    Because Perez’s substantive claims fail, amendment
    would be futile. For the same reason, we do not need to reach
    the more difficult chicken-and-egg question of whether class
    certification should be decided before standing. See Easter,
    
    381 F.3d at 962
     (explaining that the district court correctly
    addressed standing before class certification and that Ortiz v.
    Fibreboard Corp., 
    527 U.S. 815
     (1999), “does not require
    courts to consider class certification before standing”).
    Nor does Perez have standing to sue any of the defendants
    under the CLRA. The Complaint requests only injunctive
    relief under that statute. Perez has not demonstrated that he
    faces “a real or immediate threat of an irreparable injury.”
    Hangarter v. Provident Life & Acc. Ins. Co., 
    373 F.3d 998
    ,
    1021 (9th Cir. 2004) (emphasis in original) (citation and
    internal quotation marks omitted); see also Los Angeles v.
    Lyons, 
    461 U.S. 95
    , 105 (1983). Perez does not allege that he
    intends to have further hyperopic surgery and, more
    importantly, the Laser has been approved for hyperopic use
    since 2006. No post-2006 conduct is alleged. Although the
    district court dismissed the CLRA claim on the basis of
    preemption, we affirm on the alternate ground of standing,
    which is a threshold determination. See Thompson v. Paul,
    
    547 F.3d 1055
    , 1058–59 (9th Cir. 2008) (explaining that we
    can affirm a dismissal under Rule 12(b)(6) “on any ground
    supported by the record”); Bates v. United Parcel Serv., Inc.,
    10               PEREZ V . NIDEK CO ., LTD .
    
    511 F.3d 974
    , 985 (9th Cir. 2007) (en banc) (“Standing is a
    threshold matter central to our subject matter jurisdiction.”).
    II. CALIFORNIA PROTECTION OF HUMAN SUBJECTS IN
    MEDICAL EXPERIMENTATION ACT (“HUMAN SUBJECTS
    ACT”) CLAIM
    The California legislature enacted the Human Subjects
    Act “to provide minimum statutory protection for the citizens
    of [the] state with regard to human experimentation and to
    provide penalties for those who violate such provisions.”
    
    Cal. Health & Saf. Code § 24171
    . The Act lays out detailed
    guidelines for informed consent, which is required before a
    person can be “subjected to any medical experiment.” 
    Id.
    § 24175(a); see id. § 24173. For purposes of the informed
    consent provisions, “medical experiment” is defined as
    follows:
    (a) The severance or penetration or damaging
    of tissues of a human subject or the use of a
    drug or device, as defined in Section 109920
    or 109925, electromagnetic radiation, heat or
    cold, or a biological substance or organism, in
    or upon a human subject in the practice or
    research of medicine in a manner not
    reasonably related to maintaining or
    improving the health of the subject or
    otherwise directly benefiting the subject.
    (b) The investigational use of a drug or device
    as provided in Sections 111590 and 111595.
    (c) Withholding medical treatment from a
    human subject for any purpose other than
    PEREZ V . NIDEK CO ., LTD .                       11
    maintenance or improvement of the health of
    the subject.
    Id. § 24174. Perez’s claims do not fit the definition of
    “medical experiment” under either provision at issue
    here—§ 24174(a) or § 24174(b).
    A. SECTION 24174(a)
    As to § 24174(a), there is no dispute that the laser eye
    surgeries involved the use of a device upon a human subject.
    Where the parties disagree is whether the surgeries were
    performed “in the practice . . . of medicine in a manner not
    reasonably related to maintaining or improving the health of
    the subject or otherwise directly benefiting the subject.”3
    Only one published California case has addressed the
    interpretation of “medical experiment” under § 24174(a).
    Trantafello v. Medical Center of Tarzana, 
    182 Cal. App. 3d 315
    , 320 n.2 (Cal. Ct. App. 1986). In Trantafello, an
    orthopedic surgeon implanted a piece of acrylic in
    Trantafello’s neck to fill the space once occupied by a
    removed cervical disk. 
    Id. at 318
    . The surgeon did not
    advise Trantafello that he planned to use an acrylic implant or
    that this was an innovative procedure not generally accepted
    in the United States. 
    Id. at 319
    . In holding that the patient
    could not rely on the Human Subjects Act to extend the
    statute of limitations for his medical malpractice claim, the
    court stated in a footnote that the Act was “irrelevant” to
    3
    W ith regard to this and other claims, Nidek raises defenses that are
    unique to its corporate entities. Because we hold that Perez’s claims fail
    on grounds common to all of the defendants, we do not address Nidek’s
    other arguments.
    12                PEREZ V . NIDEK CO ., LTD .
    Trantafello’s claim because the Act “deals with experiments
    on human subjects in the course of pure research. . . . Here
    [the doctor] used the acrylic implant not in the course of a
    medical research program but in a course of therapeutic
    treatment for plaintiff.” 
    Id.
     at 320 n.2 (emphasis added).
    Perez quibbles with Trantafello’s restriction of the Act to
    experiments done in the course of pure research. According
    to Perez, “the fact that a procedure is meant to impart some
    benefit to a patient does not mean that it cannot also
    constitute a ‘medical experiment’ under the Act.” Without
    deciding whether there is any more play in the joints of
    § 24174(a) than Trantafello signals, the eye surgeries fell well
    outside the scope of subsection (a). Perez alleges that the
    procedures were undertaken “to attempt to correct []
    farsightedness.” Perez admits that the surgeries had a
    therapeutic purpose. He does not claim that this therapeutic
    purpose was merely incidental to a broader research goal—in
    fact, he does not claim that there was any research goal
    whatsoever. Without doubt, the hyperopic surgeries at issue
    here were “reasonably related” to “improving [Perez’s]
    health” and “directly benefiting” him. See § 24174(a).
    Perez is unable to explain why his broad definition of
    “medical experiment” would not swallow up all off-label use.
    As the Supreme Court has recognized, “‘off-label’ usage of
    medical devices . . . is an accepted and necessary corollary of
    the FDA’s mission to regulate [in the area of medical devices]
    without directly interfering with the practice of medicine.”
    Buckman Co. v. Plaintiffs’ Legal Committee, 
    531 U.S. 341
    ,
    350 (2001). The legislative history of the Human Subjects
    Act reflects that California purposefully excluded therapeutic
    off-label use from the scope of § 24174. The Assembly Bill
    originally included off-label use and the use of a drug or
    PEREZ V . NIDEK CO ., LTD .                       13
    device for which an application had been denied or
    withdrawn by the FDA or the California Department of
    Health as falling within the definition of “medical
    experiment.” A.B. 1752, Assemb. Reg. Sess. (Cal. 1977–78)
    [revisions to AB 1752 as amended in Assembly, May 23,
    1977] at 7; Assembly member Herschel Rosenthal, Letter to
    Governor Edmund G. Brown, Jr., re Assemb. Bill No. 1752
    (1977–78 Reg. Sess.), June 28, 1978, at 2 [“Rosenthal
    Letter”]. Those provisions were deleted before the bill
    became law, at least in part in response to the California
    Medical Association’s opposition to the bill. Rosenthal
    Letter 2.
    Perez’s remaining arguments—that the eye surgeries were
    not “reasonably related” to improving the proposed class
    members’ health because the doctors performed the surgeries
    “to line their own pockets” and because the surgeries were
    elective—are unpersuasive. Both arguments attempt to
    import requirements into § 24174(a) that are not found in the
    text and have nothing to do with medical experimentation.
    The standard under § 24174(a) is objective, not subjective;
    the doctors’ alleged motivations do not come into play. Nor
    does the statute embody any requirement of altruism. A
    doctor’s desire to profit from a procedure hardly transforms
    that procedure from therapeutic to experimental. Finally, the
    elective nature of a procedure is not a component of the
    statutory definition. Many elective surgeries are performed
    to improve the patient’s health. The term often is used
    merely to distinguish emergency procedures from those that
    can be scheduled at the convenience of doctor and patient.4
    4
    The medical dictionary available through M edlinePlus, a service of the
    U.S. National Library of Medicine and the National Institutes of Health,
    defines “elective” as “beneficial for the patient but not necessary for
    14                  PEREZ V . NIDEK CO ., LTD .
    And even elective surgery that is not health related may be
    “reasonably related” to “directly benefiting” a patient. For
    example, elective cosmetic surgery that ostensibly has no
    health component, that is solely undertaken for aesthetic
    reasons, and that may be lucrative for certain physicians
    nonetheless may be performed to benefit a patient and thus
    fall outside of the Act. Perez is unable to advance a rationale
    that places these LASIK surgeries within the requirements of
    the Human Subjects Act.
    B. SECTION 24174(b)
    The term “medical experiment” also includes, under
    § 24174(b), the “investigational use of a drug or device as
    provided in Sections 111590 and 111595.” These latter
    referenced sections, respectively, govern investigations,
    commonly dubbed clinical trials, conducted in accordance
    with the requirements of the FDCA, and investigations
    conducted under conditions specified by state law.
    Perez does not claim that he or any proposed class
    member was part of a clinical trial or that Physician
    Defendants performed their surgeries under the conditions
    specified in § 111595 (such as submitting reports to the state
    Department of Health Services). With respect to this claim,
    Perez’s undoing is that he affirmatively pled that he and the
    proposed class members were not participants in officially
    sanctioned clinical trials. The defendant doctor class is
    defined as “[a]ll physicians who performed Hyperopic
    LASIK and/or PRK in California with the Nidek Laser during
    survival”— for example, “an elective appendectomy.” Elective Definition,
    MedlinePlus, http://www.merriam-webster.com/medlineplus/elective (last
    visited Mar. 13, 2013).
    PEREZ V . NIDEK CO ., LTD .                15
    the Class Period, other than during an approved FDA clinical
    trial.” According to the Complaint, those “Defendants knew
    and understood that the Lasers were being used on Plaintiffs
    and the Class without their informed consent to be subjected
    to the investigational use of the Laser, and without including
    them in a sanctioned clinical trial.” Perez cannot argue both
    that he was not included in clinical trials and that the
    procedure falls under the clinical trial provisions of the
    Human Subjects Act. See Huntman v. Danek Medical, Inc.,
    No. 97-2155-IEG (RBB), 
    1998 WL 663362
    , at *6–*7 (S.D.
    Cal. July 24, 1998) (explaining that because there was no
    evidence that the plaintiff was part of an Investigational
    Device Exemption, the defendant did not need to comply with
    the informed consent provisions of the IDE regulations).
    Perez’s allegation that the “Laser was being
    investigated . . . under FDA approved clinical trials by both
    NIDEK and independent physician groups” during the class
    period does not convert his own surgery—which falls outside
    of the provisions of sections 111590 and 111595—into part
    of a clinical trial. For this reason, Perez’s reliance on Daum
    v. Spinecare Medical Group, Inc., 
    52 Cal. App. 4th 1285
    (Cal. Ct. App. 1997), is misplaced. The plaintiff in Daum
    was part of a clinical investigation conducted under the
    requirements of the FDCA. 
    Id. at 1308
    .
    Although Perez may find it “perverse and inequitable,” as
    he puts it, to provide patients admitted to clinical trials with
    “more protection than those who are subjected to the same
    experimental procedures outside the gaze of the FDA,”
    § 24174(b), by its terms, applies only to investigations
    conducted under the requirements of the FDCA or state law.
    Perez was not subject to the “investigational use” of a device
    within the meaning of § 24174(b).

    III.     FRAUD BY OMISSION CLAIMS
    Perez also alleges a common-law fraud by omission
    claim. The theory is that the defendants misled the proposed
    class by failing to disclose that the Laser was not FDA
    approved for hyperopic surgeries, even though Nidek and the
    doctors knew or should have known that the proposed class
    members believed the Laser was FDA approved for such
    surgeries. This claim of omission is expressly preempted by
    the preemption provision in the Medical Device Amendments
    (“MDA”). Even if it were not, it is impliedly preempted
    because it amounts to an attempt to privately enforce the
    FDCA.
    A. EXPRESS PREEMPTION
    The FDCA has long provided for premarket approval of
    new drugs. Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 475
    (1996). Before 1976, states were left to supervise the
    introduction of new medical devices. See Riegel v.
    Medtronic, Inc., 
    552 U.S. 312
    , 315 (2008). California was
    among a number of states that adopted regulatory measures
    governing devices. 
    Id.
     In 1976, Congress enacted the
    Medical Device Amendments to the FDCA, which “swept
    back some state obligations and imposed a regime of detailed
    federal oversight.” 
    Id. at 316
    . These amendments include an
    express preemption provision:
    Except as provided in subsection (b) of this
    section, no State or political subdivision of a
    State may establish or continue in effect with
    respect to a device intended for human use
    any requirement—
    PEREZ V . NIDEK CO ., LTD .                17
    (1) which is different from, or in addition to,
    any requirement applicable under this chapter
    to the device, and
    (2) which relates to the safety or effectiveness
    of the device or to any other matter included
    in a requirement applicable to the device
    under this chapter.
    21 U.S.C. § 360k(a). An implementing regulation provides
    that state and local requirements are only preempted by the
    MDA when the FDA “has established specific counterpart
    regulations or there are other specific requirements applicable
    to a particular device under the act, thereby making any
    existing divergent State or local requirements applicable to
    the device different from, or in addition to, the specific Food
    and Drug Administration requirements.”              
    21 C.F.R. § 808.1
    (d).
    A trio of Supreme Court cases address preemption under
    the MDA: Lohr, Buckman, and Riegel. Lohr and Riegel
    involved the MDA’s express preemption provision, and
    Buckman involved implied preemption. As we explained in
    a recent en banc decision, the “rule that emerges from these
    cases is that the MDA does not preempt a state-law claim for
    violating a state-law duty that parallels a federal-law duty
    under the MDA.” Stengel v. Medtronic, Inc., 
    704 F.3d 1224
    ,
    1228 (9th Cir. 2013) (en banc).
    In Lohr, the Court held that plaintiffs’ common-law
    claims stemming from a pacemaker failure were not
    preempted under § 360k. The allegations included claims
    that Medtronic had violated FDA regulations, and “[n]othing
    in § 360k denies Florida the right to provide a traditional
    18               PEREZ V . NIDEK CO ., LTD .
    damages remedy for violations of common-law duties when
    those duties parallel federal requirements.” 
    518 U.S. at 495
    (emphasis added). Although a plurality of the Court
    emphasized the generality of the state laws giving rise to the
    plaintiffs’ claims, “five Justices concluded that common-law
    causes of action for negligence and strict liability do impose
    ‘requirement[s]’ and would be pre-empted by federal
    requirements specific to a medical device.” Riegel, 
    552 U.S. at
    323–24 (citing Lohr, 
    518 U.S. at 512
     (opinion of
    O’Connor, J., joined by Rehnquist, C.J., and Scalia and
    Thomas, JJ.); 
    id.
     at 503–05 (opinion of Breyer, J.)). None of
    the federal laws or regulations at issue imposed device-
    specific requirements. Lohr, 
    518 U.S. at
    492–94, 500–01.
    In contrast, the Court in Riegel held that § 360k
    preempted common-law claims challenging the safety and
    effectiveness of a medical device that had received premarket
    approval from the FDA. Unlike the federal laws and
    regulations at issue in Lohr, premarket approval imposes
    device-specific requirements. Id. at 322–23. Because the
    state common-law claims related to the safety and
    effectiveness of the device and because the plaintiffs alleged
    that the device violated state tort law notwithstanding
    compliance with the federal requirements, the state claims
    were preempted. Id. at 323, 330. It did not matter that the
    common-law claims involved general tort duties of care
    applicable to other products besides medical devices. Id. at
    327–29.
    In Stengel, we “clarified preemption law under the
    MDA.” 704 F.3d at 1233. Plaintiffs’ proposed negligence
    claim for failure to warn the FDA was not preempted “insofar
    as the state-law duty parallels a federal-law duty under the
    MDA.” Id. We distinguished an Eighth Circuit case holding
    PEREZ V . NIDEK CO ., LTD .                19
    plaintiffs’ claims were preempted because, in that case,
    “plaintiffs sought to enforce state-law requirements that
    would have required Medtronic ‘to give additional warnings,
    precisely the type of state requirement that is “different from
    or in addition to” the federal requirement.’” Id. at 1232
    (quoting In re Medtronic, Inc., Spring Fidelis Leads Products
    Liability Litigation, 
    623 F.3d 1200
    , 1205 (8th Cir. 2010))
    (citation and internal quotation marks omitted). In a
    concurring opinion joined by six other judges, Judge Watford
    explained that, had the plaintiffs predicated their claim on a
    failure to warn doctors directly—an action not required by
    FDA regulations—that claim would have been preempted
    because it would have been an addition to the federal
    requirement. Stengel, 704 F.3d at 1234 (Watford, J.,
    concurring).
    The teachings from the Supreme Court cases plus our
    application of MDA preemption in Stengel lead to an obvious
    result: Perez’s fraud by omission claim is expressly
    preempted by § 360k(a).           To begin, the disclosure
    requirement at issue is “different from, or in addition to” the
    requirements applicable to the Laser under the MDA.
    § 360k(a)(1). Like the device in Riegel, the Laser was subject
    to device-specific requirements under the PMAs—including
    that it was not to be used for hyperopic corrections and was
    not permitted to be introduced into commerce for such
    corrections unless it was used in connection with an approved
    investigational use. And like the claim in Riegel, the claim
    here depends on a requirement that is “in addition to” those
    federal requirements. Perez effectively seeks to write in a
    new provision to the FDCA: that physicians and medical
    device companies must affirmatively tell patients when
    medical devices have not been approved for a certain use.
    We do not pass judgment on whether this would be a wise
    20                PEREZ V . NIDEK CO ., LTD .
    rule for the FDA to adopt. It is sufficient for our inquiry that
    it has not done so. Just as significant, the alleged missing
    disclosure—that hyperopic use was not within the scope of
    the Laser’s PMAs—“relates to the safety or effectiveness” of
    the Laser. § 360k(a)(2). In Riegel, the Court explained that
    premarket approval “is federal safety review.” 
    552 U.S. at 323
    . The sought-after disclosure also relates to “other
    matter[s] included in a requirement applicable to the device”:
    the Laser’s use in hyperopic surgeries. § 360k(a)(2). In sum,
    the fraud by omission claim is expressly preempted under the
    FDCA.
    B. IMPLIED PREEMPTION
    Perez faces another hurdle—even without express
    preemption, Perez’s fraud by omission claim is impliedly
    preempted because it conflicts with the FDCA’s enforcement
    scheme. The FDA is responsible for investigating potential
    violations of the FDCA, and the Act provides the agency with
    a range of enforcement mechanisms, such as injunction
    proceedings, civil and criminal penalties, and seizure.
    
    21 U.S.C. §§ 332
    –34, 372. Although citizens may petition
    the FDA to take administrative action, 
    21 C.F.R. §§ 10.25
    (a)
    and 10.30, private enforcement of the statute is barred: “all
    such proceedings for the enforcement, or to restrain
    violations, of [the Act] shall be by and in the name of the
    United States.” 
    21 U.S.C. § 337
    (a).
    In Buckman, the Court held that the plaintiffs’ “fraud-on-
    the-FDA” claims were impliedly preempted by the FDCA
    because they conflicted with the federal statutory scheme,
    which “amply empowers the FDA to punish and deter fraud
    against the Administration.” 
    531 U.S. at 348
    . “[C]omplying
    with the FDA’s detailed regulatory regime in the shadow of
    PEREZ V . NIDEK CO ., LTD .                         21
    50 States’ tort regimes w[ould] dramatically increase the
    burdens facing potential applicants—burdens not
    contemplated by Congress in enacting the FDCA and the
    MDA.” 
    Id. at 350
    . The Court distinguished the plaintiffs’
    claims from those in Lohr. In Lohr, the claims “arose from
    the manufacturer’s alleged failure to use reasonable care in
    the production of the product, not solely from the violation of
    FDCA requirements.” 
    Id. at 352
    . In contrast, the fraud-on-
    the-FDA claims “exist solely by virtue of the FDCA
    disclosure requirements.” 
    Id. at 353
    . Lohr “does not and
    cannot stand for the proposition that any violation of the
    FDCA will support a state-law claim.” 
    Id.
    Like the fraud-on-the-FDA claims in Buckman, Perez’s
    fraud by omission claim “exist[s] solely by virtue of the
    FDCA . . . requirements,” 
    351 U.S. 353
    , with respect to
    approved use of the Laser. As in Buckman, “the existence of
    these federal enactments is a critical element in their case.”
    
    Id.
     Although Perez is not barred from bringing any fraud
    claim related to the surgeries, he cannot bring a claim that
    rests solely on the non-disclosure to patients of facts tied to
    the scope of PMA approval.              While courts have
    acknowledged that some fraud and false advertising claims
    related to FDA status may go forward,5 Perez cites to no case
    5
    See, e.g., Photomedex, Inc. v. Irwin, 
    601 F.3d 919
    , 924–25 (9th Cir.
    2010) (explaining that, “[i]f . . . it was clear that an affirmative statement
    of approval by the FDA was required before a given product could be
    marketed and that no such FDA approval had been granted, a Lanham Act
    claim could be pursued for injuries suffered by a competitor as a result of
    a false assertion that approval had been granted”); Alpharma, Inc. v.
    Pennfield Oil Co., 
    411 F.3d 934
    , 940 (8th Cir. 2005) (allowing a plaintiff's
    false advertising claims to go forward where the plaintiff “alleged
    reasonably clear claims of FDA approval” by the defendant).
    22                   PEREZ V . NIDEK CO ., LTD .
    where a court has allowed a plaintiff to bring suit solely for
    failure to disclose lack of FDA approval.6
    The FDA knew about the allegations that the Laser was
    being used for unapproved hyperopic use and took steps to
    address the allegations by issuing warning letters and an
    Import Alert, but it did not take final action against the
    defendants. The district court explained that
    [w]hether Defendants’ use of the laser was in
    violation of the FDCA depends on, among
    other things, the scope of the PMAs, whether
    the Lasers were modified so that they were
    “adulterated” under section 501(f)(1)(B) of
    the FDCA, whether Defendants were engaged
    in a permissible “off-label” use of the Laser,
    and whether re-certification of the device was
    required under 
    21 C.F.R. § 1040.10
    . All of
    these matters rest within the enforcement
    authority of the FDA, not this Court.
    6
    In Mylan Laboratories, Inc. v. Matkari, 
    7 F.3d 1130
    , 1139 (4th Cir.
    1993), the Fourth Circuit dismissed a Lanham Act claim where the
    plaintiff contended that the very act of placing the drug on the market
    falsely implied that the drug had been properly approved by the FDA.
    Allowing such a claim would permit the plaintiff to “use the Lanham Act
    as a vehicle by which to enforce the [FDCA] and the regulations
    promulgated thereunder.” 
    Id.
     See also Summit Tech., Inc. v. High-Line
    Medical Instruments Co., 
    922 F. Supp. 299
    , 307 (C.D. Cal. 1996) (holding
    that, although “a plaintiff may bring a Lanham Act cause of action for
    affirmatively misrepresenting facts, even if the truth of those facts may be
    governed by FDA regulations,” he may not sue for “failure to disclose a
    ‘fact,’ the truth of which is currently being reviewed and determined by
    the FDA”).
    PEREZ V . NIDEK CO ., LTD .               23
    The Eighth Circuit has aptly described the “narrow gap”
    through which a state-law claim must fit to escape
    preemption by the FDCA: “The plaintiff must be suing for
    conduct that violates the FDCA (or else his claim is expressly
    preempted by § 360k(a)), but the plaintiff must not be suing
    because the conduct violates the FDCA (such a claim would
    be impliedly preempted under Buckman).” In re Medtronic,
    
    623 F.3d at 1204
     (citation and internal quotation marks
    omitted). Perez’s fraud by omission claim does not squeeze
    through this gap.
    AFFIRMED.
