XPCC Hospital Performs Third-Generation FCVB Surgery Again to Save Eyeballs from Severe Ocular Trauma
Release time: Sep 11,2025
On September 8th, Professor Li Xuejing from Xinjiang Production and Construction Corps (XPCC) Hospital successfully performed a third-generation Foldable Capsular Vitreous Body (FCVB) implantation surgery. Professor Li’s team implanted the third-generation FCVB into a patient with severe ocular trauma, preserving the patient’s hope of retaining their eye. As an innovative technology for eyeball preservation, FCVB offers a new treatment option for patients with fundus diseases such as severe retinal detachment, ocular trauma, and silicone oil-dependent eyes, playing a crucial role in saving patients’ eyeballs.
The patient, a 34-year-old female, had previously undergone right-eye vitrectomy, lens extraction, and silicone oil injection at a local hospital three months prior due to "old retinal detachment in the right eye." To have the intraocular silicone oil removed, she sought treatment at XPCC Hospital. After an outpatient examination, she was admitted with a diagnosis of "postoperative retinal detachment in the right eye."
Upon examination by Professor Li Xuejing’s team, the patient’s right eye had only light perception vision. Other findings included absence of the lens, vitreous cavity filled with silicone oil, partial loss of the inferior and inferotemporal retina, scar tissue in the inferonasal retina (with shallow retinal detachment around the scar), absence of the macular retina, and an intraocular pressure (IOP) of 18 mmHg in the right eye. The final diagnosis was postoperative silicone oil in the right eye, retinal detachment in the right eye, and optic atrophy in the right eye.
Due to the patient’s severe injury, her right eye showed signs of atrophy. An eyeball-preserving surgery was urgently needed—without timely intervention, severe atrophy would put her at risk of enucleation (eyeball removal). After conducting detailed examinations, comparing multiple treatment plans, and maintaining full communication with the patient, Professor Li’s team decided to perform the third-generation FCVB implantation surgery.
On September 8th, Professor Li’s team carried out the third-generation FCVB surgery on the patient. The folded FCVB was implanted into the eye through a minimally invasive incision. Silicone oil was then injected into the balloon via the drainage valve to support the retina and maintain intraocular pressure. The surgery was successful, with the third-generation FCVB properly placed in the patient’s right eye. A postoperative review showed the FCVB was in the correct position and the anterior chamber was deep. The patient expressed satisfaction with the surgical outcome and sincere gratitude to the medical team.
Foldable Capsular Vitreous Body (FCVB)
Professor Li explained that FCVB is the world’s first innovative product designed to simulate the natural vitreous body of the human eye. Composed of a balloon, a drainage tube, a drainage valve, and fixation loops, the FCVB’s balloon is precision-engineered via computer simulation to match the parameters of the human vitreous cavity, with a special flat design for the lens surface. Its raw material is a medical-grade silicone polymer approved for import by the U.S. Food and Drug Administration (FDA).
During surgery, the balloon is folded and implanted into the vitreous cavity. Silicone oil is injected through the drainage valve, and the balloon is fixed inside the eye using both the fixation loops and sutures on the drainage tube—this design isolates the ciliary body from damage caused by silicone oil.
The FCVB offers multiple key benefits: it preserves the posterior chamber space, allowing the ciliary body to gradually recover its function and thus maintain intraocular pressure; it prevents silicone oil emulsification and displacement; and it provides comprehensive support for the retina while preserving the eye’s shape.
The successful implementation of Chenzhou Aier Ophthalmology Hospital's first FCB surgery not only brought light to Xiao L but also marked that the hospital has stepped into a new stage in the field of minimally invasive treatment for retinal detachment. It provides a higher-quality and more precise treatment option for patients with retinal detachment in southern Hunan, especially adolescent patients.
