Albanese GM, Cerini A, Visioli G, et al. - Researchers conducted the study for assessing long term ocular biometric changes in patients with primary macula-on rhegmatogenous retinal detachment (RRD) treated with scleral buckling (SB). The medical records of patients undergoing SB surgery for macula-on RRD were reviewed. Ocular biometry was conducted before and at the most recent visit after surgery. The sample consisted of 17 patients (34 eyes) with a mean age of 57.0 ± 8.9 years. The mean follow-up duration was 50.9 ± 21.9 months (median 53.0; range 12 to 82 months) for this retrospective, observational study. According to the findings, the preoperative axial length (AXL) is the only factor that predicts an increase in AXL after SB surgery. Because scleral encircling causes a long-term shallowing of the AC, fourth-generation intraocular lens power calculation formulae should be used for patients who need cataract surgery following SB.
