The objective of the study is to evaluate:
1. Safety and efficacy of a novel foldable capsular scleral buckle (FCSB) in scleral buckling for primary rhegmatogenous retinal detachment (RRD) of medium complexity. 2. Comparison between FCSB and pars plana vitrectomy in therapeutic effects and complications in the treatment of primary RRD of medium complexity.
None
simple rhegmatogenous retinal detachment which can be treated with a single silicon sponge or silicone band (e.g. single holes, no traction, limit retinal detachment)
Complicated RRD, including macular hole within the arcade, PVR C or D, severe cataract, severe vitreous hemorrhage, unclear macular hole,
Combined with other eye diseases that affect vision prognosis.
History of other eye surgeries including cataract surgery.
