Phacoemulsification, primary posterior capsulorhexis, and capsular intraocular lens implantation for uveitic cataract.

摘要

PURPOSE: To evaluate the safety and efficacy of phacoemulsification, primary posterior capsulorhexis (PCCC), and primary intraocular lens (IOL) implantation for uveitic cataracts. SETTING: Institutional practice. METHODS: Fifteen consecutive eyes of 13 patients with various causes of uveitis received anterior capsulorhexis, phacoemulsification, PCCC, and in-the-bag implantation of a heparin-surface-modified IOL for visually disabling cataract. The safety and efficacy of the combined operation were studied prospectively. RESULTS: At a mean follow-up of 16.9 months (range 8 to 30 months), all eyes had a clear central visual area. Fourteen of 15 eyes (93.3%) had good visual improvement after surgery. Eight eyes (53%) achieved a best corrected visual acuity (BCVA) of 20/30 or better and 6 (40%), 20/20 or better. Seventy-three percent of eyes attained a BCVA of 20/80 or better. The mean improvement in visual acuity was 5.2 Snellen lines (range 0 to 11 lines). No cases of uveitis flare-up or other major complications related to the cataract surgery occurred. CONCLUSIONS: The study's preliminary results are encouraging and indicate that phacoemulsification, PCCC, and IOL implantation can be considered in patients with visually disabling uveitic cataract.
