A Clinical Comparative Study between Foldable Capsular Buckle Pressing and Conventional Scleral Buckling in the Treatment of Rhegmatogenous Retinal Detachment

Abstract

Abstract Background To compare the clinical efficacy of scleral buckling using Foldable Capsular Buckle (FCB) and conventional Scleral Buckling (SB) for the treatment of rhegmatogenous retinal detachment (RRD). Methods Analysis of 32 patients with 32 eyes with RRD treated with FCB and 28 patients with 29 eyes with RRD treated with conventional SB. Pre-operative and Post-operative examinations were recorded. The surgical success rate, best corrected visual acuity (BCVA), intraocular pressure (IOP), and persistent subretinal fluid (SRF) were compared. Results All the RRD were successfully reattached in both groups at 12 weeks postoperatively. At 12 weeks postoperatively, the BCVA improved from 1.29 ± 0.75 (LogMar) to 0.36 ± 0.25 (LogMar) (P ≤ 0.05) of the FCB group and 1.15 ± 0.69 (LogMar) to 0.33 ± 0.22 (LogMar), P < 0.000 of SB group. IOP improved in both groups, from 12.59 ± 2.83 mmHg to 15.45 ± 3.56 mmHg, P < 0.05. in FCB group and from 12.9 ± 2.68 mmHg to 15.03 ± 3.18 mmHg, P = 0.007 in SB group. In the SB group, 9 eyes showed persistent SRF postoperatively, while in the FCB group, 1 eye exhibited persistent SRF. In FCB group, the average operation time was 45.26 ± 11.24 minutes, and in SB Group, the average operation time was 97.45 ± 21.38 minutes, P < 0.0001. Conclusions Both surgeries can effectively reattach the retina and improve patients' BCVA, IOP, but the FCB external compression group has shorter surgical time, controllable complications, and high safety without pulling the extraocular muscles and the risk of oculocardiac reflex. Trial registration: The prospective observational clinical study protocol was approved by the Institutional Review Board and Ethics Committee and registered of clinical research center in the 988th Hospital of People’s Liberation Army Joint Logistic Force, China (9882019000), and registered in the the 988th Hospital of People’s Liberation Army Joint Logistic Force Clinical Research Center (LHGU20190867, 03/07/2019). The registration date was from 2019 to 2023.
