Clinical Outcomes of Pars Plana Vitrectomy and Polytetrafluoroethylene (Gore-Tex) Scleral Fixation of a Monofocal Aspheric Intraocular Lens (Akreos AO60)

Abstract

Purpose: To evaluate the visual outcomes and complications with a polytetrafluoroethylene (Gore-Tex)-fixated intraocular lens (IOL) (Akreos AO60, Bausch + Lomb). Methods: Eyes with inadequate capsule support for in-the-bag IOL implantation had pars plana vitrectomy (PPV) and IOL placement at a single center. The main outcome measures were the postoperative visual acuity (VA) and complication rates. Results: During the study, 783 surgeries were performed. The mean visual acuity gain was 28.5 Early Treatment Diabetic Retinopathy Study letters (P < .01), with a mean time to best VA of 3.05 months. Statistical hypotony (intraocular pressure <6.5 mm Hg) was present in 214 cases (27.3%), and clinical features of hypotony were present in 46 cases. Five percent of the complications were directly related to the IOL. There were 3 cases of IOL opacification, 2 with silicone oil endotamponade and 1 with perfluoropropane endotamponade. Conclusions: PPV with Akreos IOL implantation was an effective technique for secondary IOL placement. Complications directly related to the IOL were uncommon.
