The Acuity 85™ (oprifocon A) Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of refractive error (myopia, bresbyopia and/or astigmatism) in aphakic and non-aphakic persons with nondiseased eyes. The lens may be prescribed in spherical and aspheric powers ranging from -20.00 D for daily wear. The lenses may be prescribed for daily wear in otherwise non-diseased eyes that require a rigid 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 lens may be disinfected using a chemical disinfection system only.
The Acuity 85™ (oprifocon A) Rigid Gas Permeable Contact Lenses are daily wear rigid gas permeable contact lenses:
- in the power range of -20.00 to +20.00 diopters for sphere
- with base curves of 4.0 mm to 11.50 mm
- with base curve chord of 6.0 mm to 6.5 mm
- with diameter of 7.0 to 21.0 mm
The lens material (oprifocon A) incorporates an ultraviolet light absorber and lenses are lathe cut contact lenses in the following designs: spherical, toric, multifocal, and aspheric surfaces in visibility tinted material.
The provided document is a 510(k) Summary for the Acuity 85 (Oprifocon A) Rigid Gas Permeable Contact Lens, which seeks to establish substantial equivalence to a predicate device. As such, it does not detail a study involving AI or human readers, or clinical trials with acceptance criteria for device performance in the way a new medical device would typically be evaluated for accuracy or diagnostic capability.
Instead, the "acceptance criteria" here refers to demonstrating that the new device's material properties and design are substantially equivalent to a legally marketed predicate device, as per FDA guidelines for daily wear contact lenses. The "study" mentioned is primarily non-clinical testing of the material properties.
Here's a breakdown based on the information provided, framed to address your specific questions where applicable, and noting where information is not relevant to this type of submission:
1. Table of Acceptance Criteria and Reported Device Performance
For this 510(k) submission, the "acceptance criteria" are implied by the properties of the predicate device (Boston Equalens II) and the "performance" is the new device's (Acuity 85) equivalent properties. The goal is to show the new device meets or is comparable to the predicate's established properties.

§ 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.
