Phaco-emulsification in completely vitrectomized eyes: Intraoperative analysis of modified phaco sleeve

Abstract

Purpose: The purpose was to evaluate the results of modified sleeve in phacoemulsification of cataract in completely vitrectomised eyes, Materials and Methods: Twenty-five previously completely vitrectomized eyes of 23 patients having visually significant cataract were included. After through evaluation they underwent phaco-emulsification by phaco chop with a modified sleeve via temporal clear corneal incision. The modified sleeve was made by creating a small round port of approximate 1 × 1 mm size at the proximate end of the sleeve in line with the already existing ports. This port faced the posterior capsule while performing phacoemulsification. Patients were observed for any intraoperative complications. Result: The most common indication for pars plana vitrectomy in our study group was vitreous hemorrhage due to diabetic retinopathy [13 out of 25 eyes (52%)]. Intraoperative findings included miosis [seen in 3 (12%) eyes] and posterior capsular plaque [seen in 2(8%) eyes]. No other significant intraoperative complications (posterior capsular tear, dropped nucleus) were observed. Average effective phaco time was 33 sec. (±15.11). Conclusion: Though cataract surgery in postvitrectomized eyes is a challenging situation, modified sleeve prevents anterior chamber fluctuation and avoids complications arising out of it, making the surgery safe.
