CORE VITRECTOMY PRECEDING TRIPLE CORNEAL PROCEDURE IN PATIENTS AT HIGH-RISK FOR INCREASED POSTERIOR CHAMBER PRESSURE

We evaluated the effectiveness of performing a core vitrectomy to prev ent intraoperative posterior chamber pressure elevation in eyes at hig h risk for development of this complication, prior to penetrating kera toplasty, extracapsular cataract extraction and posterior chamber lens (IOL) implantation. Results in 10 cases with core vitrectomy were com pared with 10 cases without (controls); in all eyes with vitrectomy, a posterior chamber IOL was easily implanted but four eyes of the contr ol group developed vitreous complications. Our results indicate that c ore vitrectomy does facilitate IOL implantation during a triple cornea l procedure in eyes at increased risk of elevated posterior chamber pr essure.
