Intended Use

The Acuity 200™ (fluoroxyfocon A) Rigid Gas Permeable Contact Lenses are indicated for the correction of refractive error (myopia, presbyopia and/or astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. The lens may be prescribed in spheric powers ranging from -20.00 D to +20.00 D for daily wear.

Device Story

Acuity 200™ is a rigid gas permeable (RGP) contact lens manufactured from siloxanyl fluoromethacrylate copolymer. It is a lathe-cut, daily-wear lens available in spherical, toric, multifocal, scleral, and aspheric designs. The lens is tinted for visibility and includes an optional UV absorber. It is prescribed by eye care professionals to correct refractive errors (myopia, hyperopia, presbyopia, astigmatism) in aphakic and non-aphakic patients. The device functions by resting on the cornea to provide refractive correction. Clinical benefits include improved visual acuity and correction of refractive error. The device is used in a clinical setting or by the patient for daily wear.

Clinical Evidence

Prospective, open-label, multi-center, randomized concurrent-control study (90 days). 74 subjects enrolled (50 test, 24 control). Primary endpoints: visual acuity, slit lamp observations, and subjective symptoms. Results: No clinically relevant differences in safety or effectiveness between Acuity 200 and Acuity 100. Adverse events and symptom incidence (discomfort, dryness, irritation) were similar. No test eyes showed complications worse than grade 2. Study supports substantial equivalence.

Technological Characteristics

Material: siloxanyl fluoromethacrylate copolymer (fluoroxyfocon A). Production: lathe cut. Oxygen permeability: 200. Refractive index: 1.430. Hardness (Shore D): 78. Modulus: 1194 MPa. Specific gravity: 1.18. Water content: <1%. UV blocking: Yes. Dimensions: 7.0-21.0 mm diameter, 4.0-11.5 mm base curve. Sterilization: Not specified (standard manufacturing).

Indications for Use

Indicated for daily wear correction of refractive error (myopia, hyperopia, presbyopia, astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. Powers: -20.00 D to +20.00 D.

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.

# Clinical Studies

# Study Design

This study was an open-label, multi-center, randomized concurrent-control study with the treatment duration of 90 days. Seventy-four (74) subjects were enrolled in the study-of which 50 subjects wore the test lenses. Acuity 200™ (fluoroxyfocon A) Rigid Gas Permeable Contact Lens and 24 subjects wore the control lenses (Acuity 100 (hexafocon A) Rigid Gas Permeable Contact Lens). Subjects were evaluated at four independent clinical sites across the United States. Subjects wore the Test or Control lenses for 90 days bilaterally according to the randomization method.

# Trial Objective

The objective of this study was to evaluate the safety and effectiveness of the Acuity 200TM (fluoroxyfocon A) Rigid Gas Permeable Contact Lens.

## Study Endpoints

Effectiveness Endpoints - The primary efficacy endpoint in this evaluation was a comparison of the contact lens corrected visual acuity results reported for the Test lenses versus the Control lenses. The working hypothesis was that the visual acuity results are substantially equivalent between the Test and the Control lenses.

Safety Endpoints - The primary safety endpoint in this evaluation was the comparison of the objective findings (slit lamp observations and lens fitting and deposit characteristics), subjective symptoms and adverse events reported as associated with the Test lenses with those findings reported as associated with the Control lenses. The working hypothesis was that the findings are substantially equivalent between the Test and the Control lenses

The total enrollment across all clinical sites was 74 subjects (148 eyes) with 50 subjects (100 eyes) in the test group and 24 subjects (48 eyes) in the control group. Of the 74 subjects enrolled. 58 subjects completed the scheduled visits (40 subjects in the test group and 18 subjects in the control group).

There were 55 females and 18 males in the study (3.1 ratio female/male). The average age of the subjects was 53.2 years (53.5 years in the test group and 52.7 years in the control group). Sixty-two and two tenths percent (62.2%) of the enrolled subjects were habitual rigid contact lens wearers, 25.7% were habitual soft contact lens wearers, and 10.8% were habitual spectacle lens wearers.

# Clinical Study

Fifty-eight (58) of the 74 subjects enrolled completed the study. Of the 16 discontinued subjects, 9 subjects exited prior to lens dispensing. Ten subjects discontinued from the test arm (20%) and 6 subjects discontinued from the control arm (25%). In the test arm, the reasons for discontinuation included discomfort (cited by 4 subjects), lens handling (2 subjects), poor vision (1 subject), and lens positioning/fit (1 subject); the remaining

{7}------------------------------------------------

reasons cited were not directly related to the test lens (i.e. disinterest, lost to follow up, contracted shingles).

None of the completed or discontinued eyes in the test arm reported a severity of worse (>) than grade 2 for staining, edema, vascularization, hyperemia, infiltrates or any other complication. One (1) eye in the control arm reported a severity of grade 3 for bulbar redness. All other eyes treated with the control lens reported a severity of grade 2 or lower for other findings.

The test and control lenses performed similarly with respect to subject reported symptoms, problems and complaints. Symptoms reported with the highest frequency were discomfort (control 39%, test 38%), dryness (control 42%, test 31%), and irritation (control 31%, test 31%). These results indicate no clinical difference between the incidence of symptoms reported in the test arm compared to the control arm. The adverse events that occurred in the study were similar in both arms, in terms of incidence and severity.

The test and control lenses performed equally well with regards to vision safety measures-keratometry changes, refractive changes, and best corrected visual acuityover the 90-day treatment period. Trend analysis shows no emerging trends for test and control lenses for the duration of the study.

# CONCLUSIONS

The non-clinical data demonstrates the safety of the device and demonstrates that the device should perform as intended. Clinical studies were completed and demonstrate that the Acuity 2001 Rigid Gas Permeable Contact Lens performs substantially equivalent to the predicate device currently marketed for the indication of correcting ametropia.

The clinical study results establish no clinically relevant differences between the Acuitv 200™ (fluoroxyfocon A) Rigid Gas Permeable Contact Lens and Acuity 100 (hexafocon A) Rigid Gas Permeable Contact Lens (predicate device) with respect to biomicroscopy findings, symptoms or vision safety measures; this clinical investigation supports the claim of substantial equivalence between the two device types with regard to clinical safety and effectiveness.
