First Case in Southwest Yunnan! Lincang People's Hospital Successfully Performs FCVB Surgery
Release time: Oct 27,2025
Recently, the ophthalmology team of Lincang People's Hospital, supported by Professor Shi Huilin, Director of the Department, successfully carried out thefirst foldable capsular vitreous body (FCVB)surgery in southwest Yunnan. On October 18, Dr. Kang Wenwei, under the guidance of Professor Wu Chengfu from the Affiliated Hospital of Panzhihua University, successfully implanted a foldable capsular vitreous body (FCVB) in a patient at risk of eyeball atrophy, thus preserving the patient's eyeball.
The successful implementation of this surgery has filled the technical gap in this field in southwest Yunnan. It marks a milestone breakthrough for the ophthalmology department of Lincang People's Hospital in the treatment of complex fundus diseases, officially bringing it up to the advanced domestic level.
Patient Condition Overview
Three months ago, Ms. Xiao (a pseudonym) visited the ophthalmology department of Lincang People's Hospital complaining ofdecreased visual acuity in her right eye. After comprehensive admission examinations, she was diagnosed with the following conditions: 1. Traumatic cataract of the right eye; 2. Lens dislocation of the right eye; 3. Proliferative vitreoretinopathy of the right eye; 4. Retinal detachment of the right eye. She then underwentright-eye cataract extraction surgery.

Due to the non-regenerative nature of the natural vitreous body, when vitreoretinal diseases occur, it is necessary to remove the natural vitreous body through surgery and fill the eye with a suitable artificial vitreous substitute. Currently, silicone oil is the most commonly used clinical filling material.
However, long-term silicone oil tamponade is prone to a series of postoperative complications, such as complicated cataract, secondary glaucoma, corneal degeneration, and silicone oil emulsification. In a few cases, the tamponaded silicone oil may even migrate subretinally, leading to vision loss and even neurological symptoms.
Faced with such a complex and intractable condition, to prevent the patient's condition from deteriorating and avoid eyeball atrophy, the ophthalmology team made a comprehensive assessment. Taking into account the patient's condition and personal wishes, they decided to perform an eye-preserving surgery—the foldable capsular vitreous body (FCVB) implantation. Dr. Kang invited Professor Wu Chengfu from the Affiliated Hospital of Panzhihua University, who has extensive experience in FCVB surgery, to provide on-site guidance.
Before the operation, based on the patient's relevant examination results and CT scans, the ophthalmology team of Lincang People's Hospital precisely designed the surgical plan and formulated contingency measures with the assistance of 3D reconstruction technology.
The surgery was carried out as scheduled. Leading the ophthalmology team of Lincang People's Hospital, Professor Wu performed the FCVB implantation for the patient, and the operation was successfully completed. Postoperative re-examination showed that the FCVB was in the correct position in the patient's right eye, and the patient was highly satisfied with the surgical outcome.
In addition, the ophthalmology team of Lincang People's Hospital stated that the successful application of the foldable capsular vitreous body (FCVB) has opened up a brand-new and effective eye-preserving treatment pathway for patients with complex fundus diseases that previously had limited treatment options, such as recurrent retinal detachment, severe ocular trauma, and silicone oil-dependent eyes. The team will continue to monitor the patient's long-term recovery to ensure the durability of the surgical effect.
Foldable Capsular Vitreous Body (FCVB)
FCVB is the world's first innovative international product that mimics the human natural vitreous body. It consists of a capsular body, a drainage tube, a drainage valve, and a fixation loop. The capsular body is precisely designed based on computer-simulated parameters of the human vitreous cavity, featuring a special planar crystalline surface design. It is made of medical silicone polymer imported with the approval of the U.S. Food and Drug Administration (FDA).
During surgery, the capsular body is folded and implanted into the vitreous cavity, then filled with silicone oil through the drainage valve. The capsular body is secured intraocularly by double-loop sutures of the fixation loop and drainage tube, which isolates the ciliary body from damage caused by silicone oil.
The capsular body can preserve the posterior chamber space, allowing the ciliary body to gradually recover its function, rescue the dysfunctional ciliary body, and maintain intraocular pressure. It also prevents silicone oil emulsification and migration, provides all-round support for the retina, and maintains the normal shape of the eyeball.
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.
