Abstract
To report the formation of pigmented membranes on acrylic intraocular lenses (IOLs) after phacoemulsification and to determine the clinical characteristics of these pigmented membranes. Observational case series. Four eyes of three patients were found to have pigmented membranes on their acrylic IOLs (Sensar AR40). Their medical records were reviewed. The pigmented membranes were observed at 4- to 9-month intervals after phacoemulsification. Their best-corrected Snellen visual acuity (BCVA) decreased by more than 2 lines, ranging from 20/63 to 20/40. After Nd:YAG laser treatment, BCVA improved 2 to 4 lines. At 5- to 12-week intervals after Nd:YAG laser treatment, recurrences of the pigmented membranes were observed with decreased BCVA. We have observed visually significant, recurrent, pigmented membrane formation in eyes implanted with Sensar AR40 acrylic IOLs. To the best of our knowledge, pigmented membranes on acrylic IOLs have not been described previously.
