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.The underlying problemthat led to vitrectomy
may limit benefit from cataract surgery.
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 CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 2),
MEDLINE (January 1950 to April 2011), EMBASE (January 1980 to April 2011), Latin American and Caribbean Health Sciences Literature
Database (LILACS) (January 1982 to April 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com),
ClinicalTrials.gov (www.clinicaltrial.gov) and the Australian New Zealand Clinical Trials Registry (ANZCTR) (www.anzctr.org.au).
There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 19 April
2011.
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 who developed
cataracts following vitrectomy surgery. There is no evidence from randomized or quasi-randomized controlled trials on which to base clinical recommendations for surgery
for post-vitrectomy cataract. There is a clear need for randomized controlled trials to address this evidence gap. Such trials should
stratify participants by their age, the retinal disorder leading to vitrectomy, and the status of the pathologic process in the contralateral
eye. Outcomes assessed in such trials may include gain of 8 or more letters vision on the Early Treatment Diabetic Retinopathy Study
(ETDRS) scale, quality of life, and adverse events such as posterior capsular rupture. Both short-term (six months) and long-term (oneyear
or two-years) outcomes should be examined.
