Clinical evaluation of extended-wear lidofilcon B contact lenses in aphakia.

A total of 138 aphakic eyes in 109 patients were fitted with lidofilcon B contact lenses for extended wear. These patients were observed for six months to more than three years. Their problems with fit, comfort, infection, lens loss, and visual acuity were reviewed. A comparison between patients in whom the lenses were used successfully and patients in whom the lenses were used unsuccessfully was made, and the causes of failure discussed.
