The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity. The BIOFINITY (comfilcon A) Soft (Hydrophilic) Contact Lenses are indicated for daily wear. When prescribed for frequent replacement/planned replacement the lens may be disinfected using a chemical or hydrogen peroxide disinfecting systems.

Device Story

BIOFINITY (comfilcon A) is a daily wear, silicone hydrogel soft contact lens. Material consists of silicone macromers cross-linked with monomers and phthalocyanine blue handling tint. Manufactured via cast molding. Supplied sterile in blister packs with buffered saline. Available in spherical, aspherical, toric, and multifocal configurations. Used by patients for vision correction; prescribed by eye care professionals. Lens provides high oxygen permeability (Dk 128). Patients wear lenses daily; frequent/planned replacement schedule allows disinfection via chemical or hydrogen peroxide systems. Output is corrected refractive vision for the patient.

Clinical Evidence

Clinical study compared BIOFINITY to CIBA Vision Focus Night & Day. Evaluated daily wear performance and safety. Visual acuity showed no significant difference. Safety assessment via patient complaints and slit lamp observations showed no significant difference in clinical adverse events. No serious adverse events reported.

Indicated for correction of ametropia (myopia, hyperopia) and presbyopia in aphakic and non-aphakic persons with non-diseased eyes. Includes correction for astigmatism up to 2.00D (sphere/asphere) or -0.25 to -10.00D (toric).

Regulatory Classification

Identification

A soft (hydrophilic) contact lens is a device intended to be worn directly against the cornea and adjacent limbal and scleral areas of the eye to correct vision conditions or act as a therapeutic bandage. The device is made of various polymer materials the main polymer molecules of which absorb or attract a certain volume (percentage) of water.

### 9. Physicochemical Studies

The physical, optical and chemical properties of the lenses as assessed by various test methods show substantial I hi properal with the predicate devices as illustrated in the preceding table. Additional studies were conducted equired.org what leachable substances were either low or below measurable levels to assuage any concerns for its intended use.

#### 10. Toxicology Studies

Animal GLP studies were conducted and determined that BIOFINITY lenses were biocompatible for the intended use as assessed using ISO 10993 standards for cytotoxicity, maximization sensitization, ocular irritation, and systemic toxicity. All results passed with no evidence of adverse clinical effects caused by the BIOFINITY lens.

# 11. Human Clinical Studies

Clinical studies were conducted to demonstrate substantial equivalence of the BIOFINITY lens as compared with the CIBA Vision Focus Night & Day based on performance and safety. In a study of daily wear, assessment of visual acuity performance showed no significant difference between the two products. Safety as assessed by patient complaints or/and slit lamp observations showed no significant difference of clinical adverse events between the two products. There were no serious or significant adverse events attributable to the device during the study.

#### 12. Conclusions

Based on evaluations of material, manufacturing methods, lens parameters and indicated use, the BIOFINIT Y lens is substantially equivalent with the predicate, marketed lenses. Based on evaluation of chemical properties, biocompatibility and clinical studies, the BIOFINITY lens has been shown to be safe for its indicated use.
