Blepharoptosis, inferodisplacement of the upper eyelid, can be congenital or acquired. Acquired Blepharoptosis is usually aponeurotic, due to stretching or disinsertion of the levator aponeurosis. Treatment is surgical and can be performed by three common procedures - Levator advancement, Müller's muscle-conjunctival resection procedure and White line advancement. A number of reports inspected the possibility that Blepharoptosis repair procedures may cause deterioration in dry eye status. The investigators would like to assess whether there is a difference between the different procedures in their influence on dry eye status.

RECRUITINGDiagnosis of objective or subjective deterioration in dry eye status
Dry eye status will be measured by a composite of tests, including Ocular surface disease index (OSDI) questionnaire (which indicates subjective status), and a number of objective tests - Shirmer test, Flurocein dye, Lissamine green dye and tear breakup time
Time frame: 6 months
Ptosis repair procedure success
Success will be assessed by comparison of margin reflex distance1 (MRD1) measurement before and after surgery
Time frame: 6 months
