Glistenings with long-term follow-up of the Surgidev B20/20 polymethylmethacrylate intraocular lens.

PURPOSE: To evaluate the incidence and progression of small refractile vacuoles in a consecutive series of patients implanted with the Surgidev B20/20 (Surgidev Corporations, Goleta, California) polymethylmethacrylate intraocular lens. METHODS: Observational case series. A 4-year prospective study of the progression of glistenings in patients implanted with the Surgidev B20/20 intraocular lenses. In a consecutive series of 51 patients (73 eyes) that received the Surgidev B20/20 intraocular lens onset, number, and location of intraocular lens glistenings, best-corrected visual acuity, and associated ocular pathology were noted. RESULTS: With mean follow-up of 98 +/- 27 months (range, 48 to 176 months), 65 of 73 (89%) eyes had intraocular lens glistenings. Glistenings increased in frequency and size with increasing follow-up (P =.001). CONCLUSION: Glistenings may occur in polymethylmethacrylate intraocular lenses with long-term follow-up, and they are progressive.
