[Analysis of implant position after envelope technique in "white" cataract surgery]

Capsulopunture in cataract surgery doesn't allow insertion of intraocular lens in the capsular bag. Envelope technique is a easy way for this insertion. The goal of our study was to analyse the position of the intraocular lens in the capsular bag, after performing envelope technique in eyes suffering from "white" cataract. We realised on 25 eyes with "white" cataract, envelope technique. GALAND method (one superior linear capsulotomy) was realised in 15 cases and double linear capsulotomy (superior and inferior), was realised in 10 cases. The mean age of our patients was 55 years with two extremes (17 and 70 years). The mean visual acuity was 14/20. After verification, in 91.636% eyes, intraocular lenses were in the capsular bag. In 2 cases, we found a decentration. Envelope technique can lessen risks of capsular zip. It protects endothelium cells and is helpful for the insertion of the intraocular lens in the capsular bag. Envelope technique is well adapted to the surgery of "White" Cataract.
