Astigmatic Changes Secondary to Eyelid Surgeries

Astigmatic Corneal Changes Secondary to Eyelid Surgery

Eyelid surgeries change the lid position over the cornea. Previous surgeries evaluated astigmatic corneal changes in children undergoing ptosis repair. Only several studies evaluated astigmatic changes following eyelid surgeries in elderly patients. The investigators aim is to estimate this change, implications on corneal astigmatism may have great effect to future cataract surgeries for this group of patients.

Study Overview

• Status: Unknown
• Conditions: Blepharoptosis

Detailed Description

Patients registered for a lid surgery due to blepharoptosis or ptosis will undergo a topographic examination prior to and 3 months post operative in addition to their regular pre and post operative examination astigmatic shift will be mathematically measured.

• Study Type: Observational
• Enrollment (Anticipated): 30
