Tiny Capsule, Big Miracle! Ningxiang Aier Eye Hospital Successfully Performs Foldable Capsular Buckle (FCB) Implantation

Release time: May 20,2025

As a new treatment for rhegmatogenous retinal detachment, this procedure marks a step forward for the hospital’s ophthalmic fundus disease department toward minimally invasive, painless, and efficient therapy.

On May 5, Ningxiang Aier Eye Hospital successfully carried out a Foldable Capsular Buckle (FCB) implantation. Guided by Professor Chen Zhongping from Changsha Aier Eye Hospital, Professor Zou Yingfei’s team successfully implanted an FCB for a patient with rhegmatogenous retinal detachment, restoring the detached retina and improving vision. As a new treatment for rhegmatogenous retinal detachment, this procedure marks a step forward for the hospital’s ophthalmic fundus disease department toward minimally invasive, painless, and efficient therapy.

Case Overview

A 56-year-old male was admitted to Ningxiang Aier Eye Hospital on May 4, 2025, with a one-month history of floaters in the left eye and a three-day history of inferior shadow obstruction. The patient had undergone corneal refractive correction surgery in both eyes 10 years ago. Fundus examination revealed a grayish-blue hemispherical elevation in the superotemporal periphery of the left retina (not involving the macula) and a large fish-mouth-shaped tear with a radial orientation (no rolled edges) between the 1-2 o’clock positions.

Treatment Plan

After a detailed examination, Professor Zou Yingfei’s team developed a tailored treatment plan. Considering the patient’s condition, they proposed the latest minimally invasive retinal reattachment procedure—Foldable Capsular Buckle (FCB) implantation—and invited Professor Chen Zhongping (with extensive FCB surgical experience from Changsha Aier Eye Hospital) to assist.

The surgery involves subconjunctival implantation of a folded FCB, which is inflated with saline to create a scleral indentation. This presses the retinal pigment epithelium against the neuroepithelium at the tear site, sealing the defect and promoting retinal reattachment. Guided by Professor Chen, the team successfully implanted the FCB, using a folded buckle that expands like a "jack" to "lift" the detached retina back into place.

Key Innovations

3D Reconstruction Technology: Precisely locates the tear site to enhance reattachment accuracy and success rate.
Minimally Invasive Advantages: Smaller incisions reduce postoperative complications, and the removable implant avoids long-term intraocular foreign bodies.
Shorter Operation Time: Safer for patients with systemic conditions (e.g., pregnancy, diabetes, hypertension) by minimizing the risk of cardio-ocular reflex during surgery.
