title: Clinical experience with the Tangent Streak RGP bifocal contact lens.
abstract: Eighty-one screened presbyopic subjects were fitted with the Tangent Streak Bifocal (TSB) rigid gas permeable contact lens. Sixty subjects received lenses, and of this group, 42 (70%) have worn the lens successfully for 6 months or longer. Failures mainly resulted from discomfort and occasionally, reduced visual quality. Successful subjects were particularly pleased with their crisp vision at distance and near. The TSB may be the lens of choice for those presbyopic patients who require high definition visual quality at distance and near.
