简要总结
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.
