Abstract:  Objective To investigate the efficacy of foldable capsular vitreous body (FCVB) primary implantation in severe traumatic ruptures with loss of intraocular tissue and secondary implantation in silicone oil dependent eyes. Design Retrospective case series. Participants From 2017 to 2020, patients with eye traumatic ruptures (7 cases) and silicone oil dependent eyes (14 cases) underwent FCVB implantation in Beijing Aier-Intech Eye Hospital. Methods The medical records of 21 FCVB implantation patients were reviewed. The average follow-up period was (15.6±9.8) months. Main Outcome Measures Visual acuity, intraocular pressure（IOP）, anterior chamber depth, retinal reattachment and appearance. Results In 21 patients 17 cases were male (81.0%). The average age was (36.1 ± 14.2) years old. There were no serious complications during surgery in all cases. Visual acuity was improved in 8/21 cases after FCVB surgery. The mean IOP was (6.81±3.34) mmHg before surgery and (11.62±5.44) mmHg at the last follow-up. All patients had anterior chamber depth 2.5 CT or more. The retina of all patients was reattached and satisfactory appearance was obtained. No obvious emulsification or leakage of silicone oil was observed. Conclusion The primary FCVB implantation in traumatic ruptures with loss of intraocular content eyes and the secondary FCVB implantation in silicone oil dependent eyes, can maintain eyeball shape and intraocular pressure in a certain period of time, reduce the burden of multioperation injuries.
