Intended Use

BAUSCH & LOMB® PureVision™ Multi-Focal (balafilcon A) Visibility Tinted Contact Lens is indicated for daily wear for the correction of refractive ametropia (myopia, hyperopia, and astigmatism) and presbyopia in aphakic and/or notaphakic persons with non-diseased eyes, exhibiting astigmatism of 2.00 diopters or less, that does not interfere with visual acuity. The lens provides a power range of +20.00 to -20.00 diopters with add power ranging from +0.75D to +5.00D. Replacement schedules may vary from patient to patient, and should be decided by eye care practitioners in consultation with their patients. The lens is to be cleaned, rinsed and disinfected each time it is removed from the patient's eve and discarded after the recommended wearing period prescribed by the eye care professional. The lens may be disinfected using a chemical disinfection system. FREQUENT/PLANNED REPLACEMENT WEAR When prescribed for Frequent/Planned Replacement Wear, the PureVision™ Multi-Focal Contact Lens is to be cleaned, rinsed and disinfected each time it is removed from the patient's eye and discarded after the recommended wearing period prescribed by the eye care professional. The lens may be disinfected using a chemical disinfection system. DISPOSABLE WEAR When prescribed for Disposable Wear, the PureVision™ Multi-Focal Contact Lens is to be discarded after each removal.

Device Story

Hemispherical flexible silicone-hydrogel contact lens; covers cornea and portion of sclera. Corrects refractive errors and presbyopia via aspheric, concentric center-near multifocal design. Manufactured via cast molding using balafilcon A material. Used by patients under guidance of eye care practitioners. Lens requires cleaning, rinsing, and chemical disinfection for frequent/planned replacement wear, or disposal after each removal for disposable wear. Benefits include vision correction for presbyopic patients with astigmatism.

Clinical Evidence

Bench testing only. Safety and effectiveness data for balafilcon A material previously established in K944895 and K972454. No new clinical data presented.

Technological Characteristics

Material: balafilcon A (silicone-hydrogel); FDA Group III (low water/ionic); 36% water content. Design: Aspheric multifocal, concentric center-near. Diameter: 13.5-15.5 mm. Base curve: 7.5-9.5 mm. Manufacturing: Cast mold. Color additive: Reactive Blue Dye 246 (21 CFR 73.3106).

Indications for Use

Indicated for daily wear correction of refractive ametropia (myopia, hyperopia, astigmatism) and presbyopia in aphakic/notaphakic persons with non-diseased eyes; astigmatism ≤ 2.00 diopters; power range +20.00D to -20.00D; add power +0.75D to +5.00D.

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.
