A prospective evaluation of Unilens soft multifocal contact lenses in 100 patients.
One-hundred patients were fit with Unilens soft multifocal contact lenses over a 2-year period. The Unilens was selected for two reasons: the initial comfort of a soft contact lens and Unilens' purported ability to correct a wide range of refractive errors with simultaneous vision optics. The goal of this study was to find a consistent and simplified multifocal contact lens system that would satisfy a majority of the patients in the study. Forty-eight patients had no previous contact lens experience, whereas 52 patients were wearing some type of single-vision contact lens. All patients were charged the clinic's customary fee for multifocal contact lens fitting with no incentives provided for participating in the study. Success rates were very similar between first time wearers and previous contact lens wearers (71% for first time wearers and 76% for previous contact wearers). Of the four base curves available, the Unilens soft multifocal contact lenses in the 8.4 base curve demonstrated the highest success rate (81%), especially in patients with up to +2.25 D add and 1.50 D or less of cylinder.
