Indications for Use
Acuity 200™ with Tangible® Hydra PEG® (fluoroxyfocon A) Rigid Gas Permeable Contact Lens is indicated for daily wear for the correction of refractive error (myopia, hyperopia, presbyopia and/or astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. 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 Acuity™ 200 with Tangible® Hydra-PEG® (fluoroxyfocon A) Rigid Gas Permeable Contact Lens may be cleaned and disinfected using a chemical (not heat) lens care system.
Device Story
Rigid gas permeable (RGP) contact lens; manufactured from siloxanyl fluoromethacrylate copolymer (fluoroxyfocon A); surface-treated with Tangible® Hydra-PEG® polymer to enhance wetting properties. Lens is lathe-cut; available in spherical, toric, multifocal, scleral, and aspheric designs; includes UV absorber and visibility tint. Prescribed by eye care professionals for daily wear. Patient cleans/disinfects using chemical (non-heat) systems. Hydra-PEG coating improves surface wettability without altering underlying mechanical/optical properties. Benefits include vision correction and management of irregular corneal conditions.
Clinical Evidence
No clinical studies performed. Substantial equivalence supported by non-clinical bench testing, including biocompatibility (cytotoxicity, systemic toxicity, ocular irritation per ISO 10993-1:2018), lens/solution compatibility, manufacturing verification, contact angle measurement, and accelerated shelf-life/stability testing.
Technological Characteristics
Material: siloxanyl fluoromethacrylate copolymer (fluoroxyfocon A). Surface: Tangible® Hydra-PEG® polymer coating. Manufacturing: Lathe-cut. UV blocking: Yes. Oxygen permeability: 200. Refractive index: 1.430. Hardness: 78 Shore D. Modulus: 1194 MPa. Water content: <1%. Dimensions: 4.0-11.5 mm base curve, 7.0-21.0 mm diameter. Sterilization: Chemical (non-heat) lens care system.
Indications for Use
Indicated for daily wear to correct refractive error (myopia, hyperopia, presbyopia, astigmatism) in aphakic and non-aphakic persons with non-diseased eyes; also for management of irregular corneal conditions (keratoconus, pellucid marginal degeneration, post-penetrating keratoplasty, post-refractive surgery).
Regulatory Classification
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.

# Dear James Bonafini:
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.
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

## Clinical Studies
No clinical studies were deemed necessary for the Acuity 200™ with Tangible® Hydra PEG® (fluoroxyfocon A) Rigid Gas Permeable Contact Lens as Acuity 200™ fluoroxyfocon A was cleared via K201194 where clinical studies were described. Expanded indications for irregular corneas were described in K203571.
## CONCLUSIONS
The non-clinical data demonstrates the safety of the device and that the device should perform as intended. The Acuity 200™ with Tangible® Hydra PEG® (fluoroxyfocon A) Rigid Gas Permeable Contact Lens performs substantially equivalent to the predicate devices currently marketed for the indication of correcting ametropia.
