Bausch & Lomb CW 79 aphakic extended wear contact lens: multi-year follow-up.

We undertook a follow-up case study of 126 patients (146 eyes) to determine success rate and replacement rate of the Bausch & Lomb CW 79 aphakic extended wear contact lens. One hundred eighteen eyes (81%) were successful in wearing the contact lens, and 16 eyes (11%) were reported as contact lenses dropouts. Twelve eyes (8%) elected to receive intraocular lenses (IOLs). A total of 134 lenses were replaced, yielding a replacement rate of 0.3 lenses per eye per year. The average length of follow-up for successful patients was 3.7 years.
