Cangzhou Aier Eye Hospital Successfully Performs First FCVB Surgery: Ultra-Minimally Invasive and Rapid Treatment for Retinal Detachment
Release time: Dec 09,2025
On November 20, Cangzhou Aier Eye Hospital successfully carried out its firstfoldable capsular vitreous body (FCVB)surgery for the treatment of rhegmatogenous retinal detachment. The foldable capsular vitreous body (FCVB) can not only treat retinal detachment via the internal approach to preserve the eyeballs of patients with severe ocular trauma and silicone oil-dependent eyes; one of its models, thefoldable capsular buckle (FCB), can also achieve ultra-minimally invasive and rapid treatment of rhegmatogenous retinal detachment through the external approach, hereinafter referred to as FCB.
President Zhang Xin’s team successfully implanted an FCB in a 67-year-old patient with rhegmatogenous retinal detachment, achieving successful reattachment of the patient’s detached retina. As a novel surgical method for the treatment of rhegmatogenous retinal detachment, FCB implantation is a special type of scleral buckling surgery characterized by minimal invasiveness and few complications. Postoperatively, patients can maintain a free posture, which greatly improves the overall surgical experience and provides a safer and more efficient surgical option for patients.
Patient Condition Overview
"It felt like something was blocking my eye, and my vision was blurry. I didn’t take it seriously at first, but I never expected it to get worse and worse..." When 67-year-old Aunt L talked about her eye problem, she was filled with lingering fear. One year ago, she noticed a shadow-like obstruction in her left eye. With no redness or swelling, she paid little attention to it. However, the symptoms showed no sign of relief over time and suddenly worsened one day ago, prompting her to rush to Cangzhou Aier Eye Hospital for help.
After outpatient examinations, Aunt L was diagnosed withrhegmatogenous retinal detachment of the left eye, along with age-related cataracts and dry eye syndrome in both eyes. The visual acuity test results made her even more worried: her uncorrected visual acuity was only 0.15 in the right eye and 0.6 in the left eye. Fundus examination revealed a clear and normally colored optic disc, a grayish-white elevated retina from the 7 o’clock to 12 o’clock positions, and a retinal break in the peripheral retina at the 10 o’clock position—the condition brooked no delay.
Considering Aunt L’s advanced age, President Zhang Xin led the team in repeated discussions, agreeing that a surgical approach with small incisions and fast postoperative recovery would be optimal. After fully communicating with the patient and her family and explaining the advantages and disadvantages of external and internal approach surgeries, the team finally formulated afoldable capsular buckle (FCB)surgical plan for Aunt L.
On November 20, President Zhang’s team performed the FCB surgery on Aunt L, which was completed smoothly in a short time, achieving successful retinal reattachment. Two days later, laser photocoagulation was performed on the retinal break in her left eye. Postoperative examination showed that the retinal break in the left eye was located on the scleral ridge with good adherence. Aunt L’s family was satisfied with the postoperative outcome and expressed their gratitude to President Zhang’s team.

During the postoperative review, Xiao Z’s left-eye retinal break was completely closed, the symptoms of photopsia and floaters disappeared, and his corrected visual acuity improved. "We didn't expect such a quick recovery. The child only missed a few classes and returned to campus soon. We are truly grateful to the medical team!" the parents said, expressing their deep thanks to the president and Professor Zhou.
Postoperative examinations showed that the retinal break of the right eye was well-apposed on the scleral ridge, with other examination results remaining basically unchanged. The patient and her family expressed great satisfaction with the surgical outcome and extended their gratitude to the medical team.
