Brief Summary:
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.

Condition or disease

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.

eyelid displacement
patients suffering from eyelid disposition due to ptosis, blepharochalasis and are registered for eyelid surgeries will be assigned for the study

Primary Outcome Measures :
  1. astigmatic corneal decrease following eyelid surgery [ Time Frame: 3 months ]
    eyelid change in position will change the effect on corneal astigmatism measured 3 months post surgery

Secondary Outcome Measures :
  1. type of astigmatism [ Time Frame: 3 months ]
    a change from against the rule astigmatism to with the rule astigmatism following eyelid surgery will be evaluated

Other Outcome Measures:
  1. complications [ Time Frame: 3 months ]
    complications following eyelid surgery and their implications on astigmatism
