SummarySurgery for post-vitrectomy cataractVitrectomy or surgery for removal of vitreous, the substance in the center of the eye, for several conditions can result in formation or acceleration of cataract, specifically nuclear sclerotic cataract (that due to hardening and opacification of the central portion of the lens in the eye). We found no randomized trials evaluating the benefits and/or risks of cataract surgery following vitrectomy. Since cataract surgery may lead to deterioration of vision due to worsening or recurrence of the condition that prompted the vitrectomy, its role in these patients remains uncertain.

July 16. 2008 AbstractBackgroundCataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous used in the treatment of disorders that affect the posterior segment of the eye. ObjectivesThe objective of this review was to evaluate benefits and adverse outcomes of surgery for post-vitrectomy cataract with respect to visual acuity, quality of life, and other outcomes. Search strategyWe searched the Cochrane Controlled Trials Register (CENTRAL) (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library, Issue 4, 2007), MEDLINE, EMBASE, Latin America and Caribbean Health Sciences (LILACS) and the UK Clinical Research Network Portfolio Database (UKCRN).The databases were last searched on 18 January 2008. We also searched www.clinicaltrials.gov, www.controlled-trials.com, and www.actr.org.au in December 2007, in case pertinent trials were registered and were nearing completion. Selection criteriaWe planned to include randomized and quasi-randomized trials comparing cataract surgery with no surgery in adult patients who developed cataract following vitrectomy. Data collection and analysisTwo authors screened the search results independently. No studies were eligible for inclusion in the review. Main resultsWe found no randomized or quasi-randomized trials comparing cataract surgery with no cataract surgery for patients developing cataracts following vitrectomy surgery. Authors' conclusionsThere is no evidence from randomized or quasi-randomized controlled trials on which to base clinical recommendations for surgery for post-vitrectomy cataract. |
