Objectives: To investigate the sex, age, accompanying eye examination findings, and the outcomes of vitreoretinal surgery (VRS) for intraocular lens (IOL) dislocated into the vitreous cavity. Ma­te­ri­als and Met­hods: The medical records of 30 patients who underwent VRS for IOL dislocation into the vitreous cavity were retrospectively analyzed in this study. Preoperative and postoperative visual acuity, intraocular pressure, biomicroscopic, and posterior segment examination findings were assessed. Re­sults: The average age of the patients was 63.1 (range: 38-83) years. Twenty-one patients were male (70%) and 9 patients were female (30%). As etiologic causes, 18 cases (60%) had late spontaneous dislocation, 5 cases (16.6%) had dislocation after phacoemulsification surgery, 4 cases (13.3%) had trauma, 2 cases (6.6%) had previously undergone vitrectomy, and 1 case (3.3%) had undergone YAG laser capsulotomy. VRS including 23-gauge triamcinolone-assisted pars plana vitrectomy, intraocular lens extraction, posterior hyaloid membrane removing, endolaser photocoagulation, and fluid-air exchange was performed. Posterior chamber IOL implantation on to the anterior capsule in 13 cases (43.3%), anterior chamber IOL implantation in 10 cases (33.3%), and scleral fixated posterior IOL implantation in 4 cases (13.3%) were performed. The corrected visual acuity recorded at the last follow-up was better than the first visit in 23 cases (76.6%), the same in 5 eyes (16.6%), and worse in 2 eyes (6.6%). Conclusion: VRS combined IOL implantation is a successful surgery method for IOL dislocated into the vitreous cavity and can avoid poor visual outcomes. (Turk J Ophthalmol 2015; 45: 56-9)
