Intended Use

Acuity™ 100 (hexafocon A) with Tangible™ Hydra-PEG® Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of refractive error (myopia, 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 lens may be disinfected using a chemical disinfection system only. TYRO™ 97 (hofocon A) with Tangible™ Hydra-PEG® Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of visual acuity in non-aphakic persons with non-diseased eyes that are myopic, hyperopic or presbyonic and which may exhibit corneal astigmatism. 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 only by using chemical disinfection.

Device Story

Lathe-cut rigid gas permeable (RGP) contact lenses; manufactured from hexafocon A or hofocon A (fluorosilicone acrylate copolymers). Lenses feature covalently bonded Tangible™ Hydra-PEG® surface coating (polyethylene glycol-based polymer) to improve wettability. Prescribed by eye care professionals for daily wear. Patients self-apply lenses. Coating reduces sessile drop contact angle to <10°, enhancing surface properties while maintaining mechanical integrity of base material. Benefits include improved comfort and visual acuity for patients with refractive errors or irregular corneas. Disinfection requires chemical systems only.

Clinical Evidence

No new clinical data provided. Safety and effectiveness are supported by clinical data from predicate RGP lenses and previously established clinical performance of the Tangible™ Hydra-PEG® coating. Bench testing included 30-day disinfection stability, accelerated aging, bioburden testing, and ISO 10993-compliant biocompatibility (cytotoxicity, ocular irritation, systemic toxicity).

Technological Characteristics

Materials: hexafocon A or hofocon A (fluorosilicone acrylate copolymers). Surface: covalently bonded Tangible™ Hydra-PEG® (polyethylene glycol-based polymer). Form factor: lathe-cut RGP contact lens. Wettability: <10° sessile drop contact angle. Disinfection: chemical only. Connectivity: none.

Indications for Use

Indicated for daily wear correction of refractive error (myopia, hyperopia, presbyopia, astigmatism) in aphakic/non-aphakic persons with non-diseased eyes. Also indicated for management of irregular corneal conditions (keratoconus, pellucid marginal degeneration, post-penetrating keratoplasty, or 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.

Acuity 100™ (hexafocon A) with Tangible™ Hydra-PEG® and TYRO™-97 (hofocon A) with Tangible™ Hydra-PEG®

#### VII. PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

A series of in vitro and in vivo preclinical toxicology and biocompatibility tests were performed to assess the safety and effectiveness of Acuity 100™ (hexafocon A) with Tangible™ Hydra-PEG® and TYRO™-97 (hofocon A) with Tangible™ Hydra-PEG® Rigid Gas Permeable Contact Lenses. All non-clinical toxicology tests were conducted in accordance with the GLP regulation. All other testing was conducted according to valid scientific protocols.

Test results of the non-clinical testing on the device demonstrate that:

Performance Testing- Bench

- 1. The physical properties of the lenses are stable following 30 (thirty) disinfection cycles in Boston Simplus disinfection solution at ambient temperatures.
- The physicochemical and mechanical properties of the contact lenses are unchanged after 2. the addition of Tangible™ Hydra-PEG®, with the exception of wettability (contact angle).
- 3. The surface properties of the lens are stable following 30 (thirty) days of accelerated aging.
- 4. Bioburden levels are below the acceptance criteria (<100 CFU/lens) initially and following 30 (thirty) days of storage in solution at ambient temperatures.

Performance Testing- Animal

Acuity 100™ (hexafocon A) with Tangible™ Hydra-PEG® and TYRO™-97 (hofocon A) with Tangible™ Hydra-PEG®

- 5. Acute Ocular Irritation testing per ISO 10993-23 and Acute Systemic Toxicity testing per ISO 10993-11 were performed for both the final finished subject devices.
#### Performance Testing- In Vitro

- 6. Cytotoxicity testing per ISO 10993-5 was performed for both the final finished subject devices.
#### Performance Testing -Clinical

The clinical safety and effectiveness of finished rigid gas permeable contact lenses manufactured from Acuity™ 100 (hexafocon A) and TYRO™-97 (hofocon A) Rigid Gas Permeable Contact Lenses materials have been demonstrated by predicate devices. Additionally, the clinical safety and effectiveness for contact lenses treated with Tangible™ Hydra-PEG® has been previously demonstrated.

#### VIII. CONCLUSIONS

#### Validity of Scientific Data

Laboratories under Good Laboratory Practice regulations conducted toxicology, microbiology, and shelf-life stability studies following scientific protocols. The data were determined to be scientifically valid under 21 CFR §860.7.

#### Substantial Equivalence

Information presented in this 510(k) Premarket Notification establishes that the Acuity 100™ (hexafocon A) with Tangible™ Hydra-PEG® and TYRO™-97 (hofocon A) with Tangible™ Hydra-PEG® Rigid Gas Permeable Contact Lenses are as safe and effective as the predicate devices when used in accordance with the labeled directions for use and for the proposed indication.

#### 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.
