Abstract: BACKGROUND: To evaluate the functional and anatomical outcomes, and the risk of intraocular lens (IOL) decentration and opacification, in patients with rhegmatogenous retinal detachment (RRD) and secondary aphakia undergoing 25-gauge pars plana vitrectomy (PPV) with intravitreal gas tamponade and trans-scleral plug hydrophilic IOL scleral fixation. METHODS: Aphakic patients who underwent IOL scleral fixation combined with 25-G PPV and 20% sulfur hexafluoride (SF6) gas tamponade for RRD were included in this retrospective, uncontrolled study. A single-piece hydrophilic acrylic trans-scleral plug-fixated IOL was implanted. Patients were instructed to maintain face-down position for seven days postoperatively. Comprehensive clinical evaluations, including visual acuity, refraction, macular optical coherence tomography (OCT), and anterior/posterior segment assessments, were conducted at baseline and at 1, 3, 6, and 12 months, and at the final visit. RESULTS: Eleven eyes from 11 patients were included in the study. The primary retinal reattachment rate was 100%. Mean baseline best-corrected visual acuity (BCVA; 0.69 ± 0.62 LogMAR, Snellen 20/98) significantly improved to 0.23 logMAR (Snellen 20/34) at last visit. Central retinal thickness (CRT) remained stable throughout the entire follow-up. The mean final spherical equivalent refraction was − 0.18 ± 0.73 diopters. No cases of IOL dislocation or opacification were observed during the follow-up period. CONCLUSION: This procedure demonstrated satisfactory functional and anatomical results with few complications, including no significant incidence of IOL opacification or displacement observed during the follow-up period.
