Vitreous surgery as a supplement to cataract surgery.

In a series of 357 cases, vitreous surgery instruments were employed via a pars plana approach for supplementation of cataract surgery. The most frequent use was for supplementation of primary cataract surgery, either to correct vitreous loss or for performance of posterior capsulectomy. Other frequent indications included secondary cataract ("after-cataract"), retro-implant membrane, and PHPV. Improved vision was obtained in 84.3%, excluding cases in which the vitreous surgery was combined with primary cataract extraction. The complication rate was low, the most frequent problem being the presence of symptomatic cystoid macular edema in 9.2% of cases.
