简要总结
Results of retinal detachment surgery may be affected in cases with history of previous intraocular surgery.
详细描述
Pars-plana vitrectomy for management of retinal detachment has favorable visual outcome with early intervention and development of small gauge instruments, cases with previous refractive surgery may be affected by other factors that may change the final visual outcome.
In this study, we aim to analyze the effect of refractive surgeries on the final visual outcome after vitrectomy for the management of retinal detachment.
