The eLens (hexafocon A, hexafocon B and oprifocon A) Rigid Gas Permeable Contact Lenses for Daily Wear are indicated for the correction of refractive ametropia (myopia, astigmatism and presbyopia) in aphakic and not aphakic persons with non-diseased eyes. Also, the lenses may be prescribed in otherwise non-diseased eyes that require a gas permeable contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive (e.g., LASIK) surgery. The lenses may be disinfected using a chemical disinfection system only.

The eLens (hexafocon A, hexafocon B and oprifocon A) Rigid Gas Permeable Contact Lenses for Daily Wear Ortho-K is indicated for daily wear in an orthokeratology fitting program for the temporary reduction of myopia of up to 5.00 diopters in non-diseased eyes. The lenses may be disinfected using a chemical disinfection system only.

Note: To maintain the orthokeratology effect of myopia reduction, lens wear must be continued on a prescribed wearing schedule.

AI/ML Overview

This document is a 510(k) Premarket Notification for the eLens (hexafocon A, hexafocon B and oprifocon A) Rigid Gas Permeable Contact Lenses for Daily Wear and eLens (hexafocon A, hexafocon B and oprifocon A) Rigid Gas Permeable Contact Lenses for Daily Wear Ortho-K.

The provided text does not describe a study that uses AI or machine learning models to meet acceptance criteria, but rather focuses on substantial equivalence to existing predicate devices for rigid gas permeable contact lenses. Therefore, I cannot extract information related to AI/ML model acceptance criteria, performance, sample sizes for test/training sets, expert adjudication, or MRMC studies from this document.

The document primarily covers:

Device Description: Materials, properties, and available parameters of the contact lenses.
Intended Use/Indications for Use: Correction of refractive ametropia (myopia, hyperopia, astigmatism, presbyopia), management of irregular corneal conditions, and temporary reduction of myopia for Ortho-K.
Predicate Devices: Lists several "Boston" brand contact lenses as predicate devices.
Substantial Equivalence: Argues that the eLens is substantially equivalent to the predicate devices based on common classification, product code, FDA Group #, USAN, production method (lathe-cut), actions, intended use, and indications for use.
Performance Data: States that non-clinical and clinical performance data have been addressed by reference to the predicate devices and in previous applications.

Therefore, I cannot fulfill the request to discuss acceptance criteria and study proving the device meets those criteria, as the document does not contain information about an AI/ML-based study.

Dear Bret Andre:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{1}------------------------------------------------

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

Risks and Benefits

The risks of the subject device are the same as those normally attributed to the wearing of rigid gas permeable (RGP) daily wear contact lenses. The benefits to the patient are the same as those for other RGP contact lenses.

Regulation Number and Section

§ 886.5916 Rigid gas permeable contact lens.

(a)
Identification. A rigid gas permeable contact lens is a device intended to be worn directly against the cornea of the eye to correct vision conditions. The device is made of various materials, such as cellulose acetate butyrate, polyacrylate-silicone, or silicone elastomers, whose main polymer molecules generally do not absorb or attract water.(b)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.
(c)
Date PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the act is required before a device described in paragraph (b)(2) of this section may be commercially distributed. See § 886.3.
