Long-term ocular biometric variations after scleral buckling surgery in macula-on rhegmatogenous retinal detachment

Abstract Background Myopic shift and biometric ocular changes have been previously observed after scleral buckling (SB) surgery in rhegmatogenous retinal detachment (RRD), but long term-term outcomes had not yet explored. The purpose of present study is to evaluate term patients with primary macula-on RRD treated SB. Methods In this retrospective, observational study, we reviewed the medical records undergoing SB for RRD. Ocular biometry was performed before at most recent visit surgery. Axial length (AXL), anterior chamber depth (ACD), corneal astigmatism spherical equivalent eyes were compared as well those fellow eyes. Results Thirty-four 17 a mean age 57.0 ± 8.9 years included. follow-up duration 50.9 21.9 months (median 53.0; range 12 82 months). A significant postoperative AXL increase 0.83 mm concomitant myopic 1.35 diopters operated ( p < 0.0001). preoperative only predictive factor change (B = 0.152, 95% CI 0.059 0.245, β 0.668, P 0.003). Compared eyes, ACD shallowing 0.1 found 0.05), while there no long-term astigmatism. Conclusions We show that Scleral encircling induces AC, therefore fourth generation intraocular lens (IOL) power calculation formulae should be used requiring cataract
