Surgery for post-vitrectomy cataract

Do DV. "Surgery for post-vitrectomy cataract." Cochrane Database Syst Rev. 2008 Jul 16;(3):CD006366.. 2008.


BACKGROUND: Cataract 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. OBJECTIVES: The 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 STRATEGY: We 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,, and in December 2007, in case
pertinent trials were registered and were nearing completion. SELECTION CRITERIA:
We 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 ANALYSIS: Two authors screened the search results
independently. No studies were eligible for inclusion in the review. MAIN
RESULTS: We found no randomized or quasi-randomized trials comparing cataract
surgery with no cataract surgery for patients developing cataracts following
vitrectomy surgery. AUTHORS' CONCLUSIONS: There is no evidence from randomized or
quasi-randomized controlled trials on which to base clinical recommendations for
surgery for post-vitrectomy cataract.
