| Abstract: | We evaluated the effectiveness of performing a core vitrectomy to prevent intraoperative posterior chamber pressure elevation in eyes at high risk for development of this complication, prior to penetrating keratoplasty, extracapsular cataract extraction and posterior chamber lens (IOL) implantation. Results in 10 cases with core vitrectomy were compared with 10 cases without (controls); in all eyes with vitrectomy, a posterior chamber IOL was easily implanted but four eyes of the control group developed vitreous complications. Our results indicate that core vitrectomy does facilitate IOL implantation during a triple corneal procedure in eyes at increased risk of elevated posterior chamber pressure. |
