Intended Use

OPTIMUM GP (roflufocon D. roflufocon E) and HEXA100 (hexafocon A) Daily Wear Contact Lenses are indicated for the correction of refractive ametropia (myopia, astigmatism and presbyopia) in aphakic persons with non-diseased eyes. Also, the lenses may be prescribed 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 surgery. Furthermore, eyes suffering from certain ocular surface disorders may benefit from the physical protection, aqueous hydrated environment and the saline bath provided by scleral lens designs. OPTIMUM GP (roflufocon D) and HEXA100 (hexafocon A) Daily Wear Contact Lenses are indicated for therapeutic use for the management of irregular and distorted corneal surfaces where the subject: 1. cannot be adequately corrected with spectacle lenses 2. requires a rigid gas permeable contact lens surface to improve vision 3. is unable to wear a corneal rigid gas permeable lens due to corneal distortion or surface irregularities Common causes of corneal distortion include but are not limited to corneal infections, trauma, tractions as a result of scar formation secondary to refractive surgery (e.g. LASIK or radial keratotomy) or corneal transplantation. Causes may also include corneal degeneration (e.g. keratoconus, keratoglobus, pellucid marginal degeneration, Salzmann's nodular degeneration) and corneal dystrophy (e.g., lattice dystrophy, granular corneal dystrophy, Reis-Bucklers dystrophy, Cogan's dystrophy). The OPTIMUM GP (roflufocon D, roflufocon E) and HEXA100 (hexafocon A) Daily Wear Contact Lenses are also indicated for therapeutic use in eyes with ocular surface disease (e.g. ocular Graft-versus-Host disease, Sjögren's syndrome, dry eye syndrome and Filamentary Keratitis), limbal stem cell deficiency (e.g. Stevens-Johnson syndrome, chemical radiation and thermal burns), disorders of the skin (e.g. atopy, ectodermal dysplasia), neurotrophic keratitis (e.g. Herpes simplex, Herpes zoster, Familial Dysautonomia), and corneal exposure (e.g. anatomic, paralytic) that might benefit from the presence of an expanded tear reservoir and protection against an adverse environment. When prescribed for therapeutic use for a distorted cornea or ocular surface disease, the OPTIMUM GP (roflufocon D, roflufocon E) and HEXA100 (hexafocon A) Daily Wear Contact Lenses may concurrently provide correction of refractive error. The lenses may be disinfected using a chemical disinfection (not heat) system only.

Device Story

Rigid gas permeable (RGP) contact lenses; lathe-cut from fluoro-silicone acrylate materials (roflufocon D, roflufocon E, hexafocon A). Optional Tangible Hydra-PEG coating (polyethylene glycol-based polymer) for enhanced wettability. Used by patients with refractive errors or irregular corneal conditions/ocular surface diseases. Lenses provide refractive correction, physical protection, and an aqueous hydrated environment (scleral design). Prescribed by eye care professionals. Shipped dry or wet in polypropylene cases. Chemical disinfection only.

Indications for Use

Indicated for correction of refractive ametropia (myopia, astigmatism, presbyopia) in aphakic/non-aphakic persons with non-diseased eyes; management of irregular corneal conditions (keratoconus, pellucid marginal degeneration, post-surgical); therapeutic use for ocular surface disorders (Graft-versus-Host, Sjögren's, dry eye, Filamentary Keratitis, limbal stem cell deficiency, neurotrophic keratitis, corneal exposure) requiring expanded tear reservoir/protection.

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.

### The OPTIMUM GP (roflufocon D, roflufocon E) and HEXA100 (hexafocon A) Daily Wear

Contact Lenses are available with or without Tangible™ Hydra-PEG-which is a thin polyethylene glycol (PEG)-based polymer that is covalently bonded to the surface of the contact lens and is designed to enhance the surface properties of the contact lens while retaining the mechanical properties of the underlying material. When treated with Tangible™ Hydra-PEG, the underlying material is encapsulated in a thin layer of polymer that results in measurable improvement of wettability compared to untreated lenses.

{6}------------------------------------------------

The surface properties of roflufocon D, roflufocon E, and hexafocon A materials uncoated and coated with Tangible Hydra-PEG are depicted in the following table:

#### VII. PERFORMANCE DATA

### ~ Non-Clinical Studies ~

The purpose of this application is to modify the labeling of previously FDA cleared RGP contact lenses/materials to include a therapeutic indication for use. Non-clinical testing to demonstrate the safety and effectiveness of contact lenses manufactured from roflufocon D. roflufocon E, and hexafocon A materials has been addressed in previous applications.

### ~ Clinical Studies ~

Clinical performance data to demonstrate the safety and effectiveness of contact lenses manufactured from roflufocon D, roflufocon E, and hexafocon A has been previously addressed.

## VIII. CONCLUSIONS

### Substantial Equivalence

Information presented in this Premarket Notification establishes that OPTIMUM GP (rofflufocon D, roflufocon E) and HEXA100 (hexafocon A) Daily Wear Contact Lenses are as safe and effective as the predicate device 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.
