Intended Use

HDS HI 1.54™ rigid gas permeable contact lenses are indicated for daily wear as recommended by the eye care practitioner. HDS HI 1.54™ rigid gas permeable spheric and bifocal contact lenses are indicated for the correction of refractive ametropia in not-aphakic persons with non-diseased eyes that are nearsighted (myopic), farsighted (hyperopic), and may exhibit corneal astigmatism up to 4.00 diopters that does not interfere with visual acuity. HDS HI 1.54™ toric contact lenses are indicated to correct astigmatism of up to 6.00 diopters. HDS HI 1.54™ bifocal lenses are indicated to treat presbyopia up to +4.00 D add power. HDS HI 1.54™ contact lenses are indicated for management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty, radial keratotomy, or LASIK surgery, in otherwise non-diseased eyes.

Device Story

HDS HI 1.54 (pahrifocon A) is a rigid gas permeable (RGP) contact lens; lathe-cut from thermoset copolymer (acrylate, silicone acrylate, fluorosilicone acrylate). Available in spherical, aspheric, bifocal, or toric designs. Posterior curve provides fit; anterior curve provides refractive correction; peripheral curve system facilitates tear exchange. Used by eye care practitioners to correct refractive errors and manage irregular corneal conditions. Patients wear lenses daily. Clinical benefit includes improved visual acuity and management of corneal irregularities. Device is non-implantable; worn on the ocular surface.

Clinical Evidence

Multisite, randomized, double-masked clinical study; 76 subjects (152 eyes) enrolled; 64 subjects completed. Primary endpoints: safety (slit lamp findings, adverse events) and efficacy (visual acuity, keratometry, refraction, lens comfort). No adverse events reported. Slit lamp findings primarily grade 1 (trace). Lens comfort rated 'very good' (4.04/4.07). Refractive changes within 1.00D for >93% of eyes. Study supports substantial equivalence.

Technological Characteristics

Thermoset copolymer (acrylate, silicone acrylate, fluorosilicone acrylate). Refractive index 1.54; Dk 22x10-11 (ISO 9913-1). Hardness 84 Shore D. Lathe-cut manufacturing. Plasma treatment optional. Clear or tinted versions.

Indications for Use

Indicated for daily wear in non-aphakic, non-diseased eyes for correction of myopia, hyperopia, and corneal astigmatism (up to 4.00D for spheric/aspheric/bifocal, up to 6.00D for toric). Also indicated for presbyopia (up to +4.00D add) and irregular corneal conditions (keratoconus, pellucid marginal degeneration, post-penetrating keratoplasty, post-radial keratotomy, or post-LASIK).

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.

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

Marketed device to which equivalence is claimed is FluoroPerm 30 (paflufocon c).

HDS HI 1.54 (pahrifocon A) rigid gas permeable contact lenses for daily wear are available as lathe cut contact lenses with spherical, aspheric, bifocal or toric anterior and/or posterior, or, bitoric surfaces in clear and tinted versions. The posterior curve is selected so as to properly fit an individual eye and the anterior curve is selected to provide the necessary optical power to correct refractive error. A peripheral curve system on the posterior surface allows tear exchange between the lens and the cornea.

The HDS HI 1.54 rigid gas permeable contact lens material is a thermoset copolymer derived from acrylate, silicone acrylate, and fluorosilicone acrylate monomers, dimers and oligomers.

The HDS HI 1.54 rigid gas permeable tinted lenses offer a handling aid for locating the lens and may be plasma treated.

### Summary of Non clinical test results

In addition to the non-clinical tests indicated by the table above, studies were performed on the saline extractives following the method of the USP <88> BIOLOGICAL REACTIVITY TEST and toxicological procedures for Ocular Irritation, Systemic Toxicity and Cytotoxicity (ISO 10993-10, ISO 10993-11). These studies found the saline extractives to be small and in line with the predicate material and no indications of toxicity nor irritation were observed in the procedures.

### Summary of clinical results

Seventy six (76) subjects (152 eyes) were enrolled and dispensed in the multisite, randomized, double masked clinical study to provide data that support the presumption of equivalence of the HDS HI 1.54™ investigational

{3}------------------------------------------------

lenses to a historical control contact lens. Sixty four (64) subjects (84.2%) completed the study and 12 subjects (15.8%) were discontinued. The population demographics were similar to previous contact lens studies.

Of the ten Test subjects who discontinued, Difficulty Cleaning Lenses (3 subjects) and Poor Comfort (2 subjects), Poor Vision (1 subject) and Poor Comfort (2 subjects) accounted for 80% of the discontinuations. Two Control subjects discontinued, one for Loss of Interest and one for Poor Comfort

There were no adverse events reported during the study. The only study related complications were slit lamp findings of grade 3 for injection. Each of these resolved without complication.

Slit lamp findings were reported at frequencies within expected values and the positive slit lamp observations were primarily grade 1 (trace). Staining and injection were reported most frequently. Subject reports of no symptoms were lowest at the 1 week visit for both the Completed Test and Control eyes and then increased over the remainder of the study. Discomfort was reported most frequently (13.7% of Completed Test eye visits and 12.3% of Completed Control Eye visits). .

Lens comfort was rated as an average of 4.04 (very good) for the Completed Test eyes and 4.07 (very good) for the Completed Control eyes. This compared to a baseline value of 3.96 for the Test eyes and 4.23 for the Control eyes with the pre-study habitual correction.

Keratometry changes were within 1.00 diopter for 93.1% of the Completed Test eyes and 96.4% of the Completed Control eyes. Manifest refraction changes were within 1.00 diopter for 97.9% of the Completed Test eyes and 98.2% of the Completed Control eyes.

One eye of the 63 Completed Test eyes targeted for full distance vision was reported to show a decrease in contact lens visual acuity from the baseline best corrected visual acuity of greater than 0.20 logMAR. The reason for the loss was a reported baseline measurement error. One eye of the 48 Completed Control eyes targeted for full distance vision was reported to show a decrease in contact lens visual acuity from the baseline best corrected visual acuity of greater than 0.20 logMAR. The reason cited for the decrease was lenses being switched eye for eye.

Average lens wearing time was stable at over 13 hours per day for the Completed Test and Control subjects and showed a decrease over time for the discontinued eyes.

Forty nine (49) lens replacements were made for 40 of the 152 eyes dispensed in the study. The replacements were predominantly for deposits (8) or parameter and power change (21) which together account for 59% of the lens replacements. Discomfort was cited for 18.4% (5 test and 4 control lenses) of the lens replacements. Five lenses (10%) were replaced due to loss.

The results of the clinical evaluation of the Paragon HDS HI 1.54™ contact lenses provide evidence of substantial equivalence to the historical control, Paragon Fluroperm® 30 contact leuses.

#### Conclusions drawn from studies

The conclusions drawn from the nonclinical and clinical tests (discussed above) are that the device is as safe, as effective, and performs as well as or better than the predicate device .
