Visual Outcome of Vitrectomy After Refractive Surgery

Not Applicable

Recruiting

• Conditions: Retinal Detachment; Refractive Errors
• Interventions: Procedure: Vitrectomy

• Registration Number: NCT05583253
• Lead Sponsor: Benha University

Brief Summary

Results of retinal detachment surgery may be affected in cases with history of previous intraocular surgery.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Vitrectomy group with previous refractive surgery	Vitrectomy	Cases with primary retinal detachment that are prepared for pars-plana vitrectomy with previous history of refractive surgery.
Vitrectomy group with no previous intraocular surgery	Vitrectomy	Subjects with primary retinal detachment that are prepared for pars-plana vitrectomy with no previous history of intraocular surgery.

Primary Outcome Measures

Name	Time	Method
Visual acuity	Baseline and 6 months after surgery.	Changes in visual acuity from baseline and at the 6th month of follow-up measured by snellen chart and converted to logMAR units for statistical analysis.

Secondary Outcome Measures

Name	Time	Method
Corneal endothelial cells count	Baseline and 6 months after surgery.	Changes in corneal endothelial cells counts measured by specular microscopy in cells/millimeters2 units.
