# Efficacy and visual outcomes of the foldable capsular buckle scleral buckling in rhegmatogenous retinal detachment

## TL;DR

This study examines how well a foldable capsular buckle works in treating retinal detachment, showing it can reattach retinas and improve vision.

## Contribution

The study introduces the foldable capsular buckle as a promising new method for treating retinal detachment with shorter operation times.

## Key findings

- All six patients achieved successful retinal reattachment after FCB surgery.
- There was no significant change in intraocular pressure before and after surgery.
- The foldable capsular buckle resulted in a mean operation time of about 37 minutes.

## Abstract

To investigate the difference in the effectiveness and refraction of the foldable capsular buckle (FCB) in rhegmatogenous retinal detachment (RRD).

Six patients with simple RRD were treated for FCB scleral buckling at Xiamen Eye Center of Xiamen University from October 2023 to February 2024. The parameters assessed included demographic data, clinical data such as preoperative ocular axis, corneal endothelial count, macular foveal thickness, operative time, preoperative and final follow-up intro ocular pressure (IOP), retinal attachment status, and postoperative complications. Refractive change before and after surgery, including sphere, cylinder degree, spherical equivalent, and absolute spherical equivalent difference were compared.

All six patients with sound retinal reattachment after FCB scleral buckling, including two men and four women, mean age 41.33 ± 12.40 years old, duration before surgery onset to 7.17 ± 7.16 days, FCB mean operation time 36.67 ± 13.07 min, Preoperative IOP mean 13.35 ± 2.64 mmHg and mean 21.12 ± 8.09 mmHg of final follow-up IOP; there was no significant difference between preoperative IOP and follow-up IOP (p = 0.050). The preoperative sphere range was −6.25 to +2.50 D, and the cylinder range was −2.50 to +1.00 D; the absolute spherical equivalent difference before and after was 1.60 ± 1.69 degrees.

FCB can achieve retinal reattachment and restore visual function in cases of RRD. The shorter duration of external scleral buckle compression with FCB suggests that FCB scleral buckling holds greater promise in the clinical treatment of RRD caused by retinal tears.
