To determine the long-term anatomic outcomes and surgical complications of pars plana vitrectomy (PPV) and 4-point Gore-Tex-sutured Akreos AO60 intraocular lens (IOL) scleral fixation. Retrospective, multicenter, multisurgeon case series. Ninety-seven patients in tertiary eye care centers. The patients underwent PPV and intraocular fixation of the Akreos AO60 IOL using Gore-Tex CV-8 sutures between January 2015 and April 2020. The inclusion criteria were aphakia, no capsular support, and a minimal 1 year of follow-up. Uncorrected visual acuity (VA), complication rates or types, and refraction. Data from 101 eyes of the 97 patients were analyzed (mean follow-up duration, 33.4 months; range, 12-62 months). The mean ± standard deviation uncorrected logarithm of the minimum angle of resolution VA improved from 1.04 ± 0.73 (20/200 Snellen equivalent) before surgery to 0.66 ± 0.65 (20/80) at 6 months after surgery (P < 0.001). The most prevalent complications included hypotony (12.9%), ocular hypertension (12.9%), corneal edema (8.9%), cystoid macular edema (6.9%), and vitreous hemorrhage (5.9%). Refraction was measured between 3 and 6 months after surgery, and 61.8% of the patients had spherical equivalent of ± 2.0 diopters. Most complications occurred in the first postoperative month and resolved spontaneously or with medical treatment. The results demonstrated that this surgical technique is well tolerated by the eyes, with a low complication rate in the long term. The rates of IOL opacification were infrequent for up to 62 months of follow-up.
