PHACOEMULSIFICATION OF BROWN CATARACTS ON AVITREAL EYES

Abstract

Analysis of the features of surgical treatment of brown cataracts in the eyes with previously performed posterior vitrectomy. The study included 25 patients (25 eyes) with nuclear cataracts 6+ density according to LOCS III classification. All patients underwent microinvasive posterior vitrectomy more than 6 months ago. Microcoaxial (2.2 mm) phacoemulsification of cataract with implantation of flexible intraocular lens was planned for all patients. In 15 patients (60 %), a system of capsule hooks was used in order to support the capsule bag 4 in 16 % of cases and 6 in 44 % of cases.Results and discussion. Sutureless surgery were performed in 24 patients (96 %). In one case with nigra cataract despite the use of capsule hooks, due to the high risk of dislocation of the lens into the vitreous cavity, the surgery was converted into a large incision. Microcoaxial phacoemulsification is the surgery of choice in the case of a combination of dense lens and lack of vitreous support. The use of capsular hooks greatly simplifies surgery and increases the chances of sutureless surgery.
