Use of selective laser capsulotomy for mature white cataracts: Initial experience in Indian eyes

Abstract

Purpose: To report the initial experience of performing capsulotomy in eyes with mature white cataracts using selective laser capsulotomy (SLC) in Indian eyes. Methods: This was a prospective, noncomparative, open-label study. All adults presenting to our institution with mature cataracts whose pupils dilated >6 mm and who were willing for phacoemulsification were invited to participate. During surgery, after staining the anterior capsule with a proprietary trypan blue, the CAPSULaser device (Excel-Lens Inc, Los Gatos, CA, USA) was used to create a capsulotomy of size ranging from 5 to 5.5 mm and phacoemulsification was carried out. The primary outcome was the size, centration, and continuity of the capsulotomy edge at the end of the surgery. Secondary outcomes were the surgical time for capsulotomy, capsulotomy centration on the intraocular lens (IOL) at 3 months, and adverse effects. Results: Thirty eyes were studied of 30 patients who were recruited with a mean age of 66.4 ± 8.3 years, of which 17 (57%) were men. The intraoperative size of capsulotomy was the same as intended in all eyes and the edges were smooth. None of the eyes experienced any visible capsular tears or run out events; one had a capsular tag. The time for capsulotomy including capsular staining was 3 ± 0.23 min. All IOLs were well centered at 3 months with a capsulotomy size remaining the same. The endothelial cell count had dropped by 8% at 3 months post-op, and the vision improved significantly to 0.03 log of minimum angle of resolution. None of the eyes experienced any intraoperative complications or laser-induced adverse effects. Conclusion: SLC was a safe and effective technique providing precise, well-centered anterior capsulotomies in mature white cataracts.
