Delayed visual loss after pars plana vitrectomy for retained lens fragments

Purpose: To report visual results and postoperative complications in patients undergoing vitrectomy for retained lens fragments. Methods: Retrospective, noncomparative, interventional case series of 42 consecutive patients undergoing vitrectomy for retained lens fragments by a single surgeon, all with a minimum of 6 months' follow-up. The main outcome measurement was best corrected visual acuity at 3 months and at final follow-up visit. Results: Although 67% of eyes achieved a postoperative visual acuity of 20/40 or better at 3 months, 17% had events during follow-up that resulted in loss of vision to less than 20/40. Final best corrected visual acuity 20/40 or better was achieved in 50% of eyes. Retinal detachment occurred in 17%, and 21% of eyes required long-term therapy for glaucoma. Conclusion: Patients undergoing vitrectomy for retained lens fragments often develop delayed visual loss. Long-term surveillance is necessary in these patients.
