Brief Summary

The purpose of this study is to determine the feasibility, primary safety and efficacy of foldable capsular vitreous body (FCVB) in the treatment of retinal detachment, based on the multi-center clinical trial.

Detailed Description

Previous clinical trial have demonstrated that foldable artificial vitreous body (FCVB),with balanced salt solution (BSS) filled in 11 patients during three-months observation,or silicone oil filled in 4 patients during a six-month observation respectively, can be transplanted into the vitreous body easily, and performances good safety and efficacy in the treatment of severe retinal detachment.

Current multi-center clinical trial was to determine the feasibility, primary safety and efficacy of FCVB with silicone oil filled in the treatment of retinal detachment in 120 patients.
