Purpose: Historical studies have suggested that the lens may provide a barrier to the angiogenic stimulus in proliferative diabetic retinopathy (PDR), reducing the risk of rubeosis iridis (RI). With the use of modern vitreoretinal techniques including endophotocoagulation, the rationale for preserving the lens during diabetic vitrectomy may be less compelling. The lens may also serve as an impediment during intraoperative surgical maneuvers and, due to postoperative cataract progression, subsequent visual recovery. This study sought to determine the effect of lens status upon anatomic results in primary diabetic vitrectomy. Methods: A total of 151 eyes of patients with PDR were included in the study. Preoperatively, 93 eyes were phakic and the remaining eyes (n=58) were either aphakic (n=8) or pseudophakic (n=50). At the time of initial vitrectomy, 14 eyes underwent lensectomy and 9 patients underwent lens extraction and IOL implantation. The eyes that remained phakic after surgery (n=70) were compared to the eyes that were either aphakic or pseudophakic (nonphakic, n=81) with respect to intraoperative and postoperative complications and ultimate anatomic success. Results: Despite the nonphakic eyes having worse preoperative traction, these eyes had reduced intraoperative complications and higher initial postoperative success rates compared to phakic eyes, as summarized in the table below. Rubeosis iridis developed in 3 eyes (1 phakic and 2 pseudophakic eyes).
