Incidence and management of rhegmatogenous retinal detachment after pars plana vitrectomy and sutureless scleral-fixated intraocular lens

PURPOSE: To evaluate the incidence, risk factor(s), and surgical outcomes of rhegmatogenous retinal detachment (RRD) in patients undergoing pars plana vitrectomy (PPV) with sutureless scleral-fixated intraocular lens implantation (SFIOL). METHODS: Records of patients (1311 eyes, 1234 patients) who underwent PPV and sutureless SFIOL from 2017 to 2018 were retrospectively analyzed. RESULTS: The indications SFIOL were subluxated lens (33.7%), dislocated IOL (21.7%), surgical aphakia (20.1%), congenital lens subluxation (11.1%), nucleus drop (6.9%), and post-open globe injury (OGI) repair (6.5%). History of closed-globe injury (CGI) was present in 27.2% eyes.Twenty-two eyes (1.7%) developed RRD. The incidence of RRD in eyes, which underwent SFIOL surgery for subluxated lens, dislocated IOL, surgical aphakia, congenital lens subluxation, nucleus drop, and post-OGI repair was 1.4% (n = 6), 2.5% (n = 7), 1.1% (n = 3), 3.4% (n = 5), 0 and 1.2% (n = 1), respectively (P = 0.382). The incidence of RRD in eyes with and without CGI was 1.7% each (P = 0.996).Twenty-one eyes underwent RD surgery. Retinal reattachment was achieved in 76.2% eyes, while 66.7% eyes required only one surgery. The eyes in which retina failed to reattach had a high grade of proliferative vitreoretinopathy present at the time of presentation. Final best-corrected visual acuity of ≥20/60 and <20/60 to ≥20/200 and <20/200 was seen in 38.1%, 19.0%, and 42.9% eyes. CONCLUSION: Eyes with the congenital subluxated lens are at a marginally higher risk of developing post-SFIOL RRD. The surgical outcome of RD surgery in these eyes is good.
