To investigate the change in upper eye lid position after cataract operation with retrobulbar anesthesia and bridle suture, we studied 60 eyes of 60 patients randomized into 3 groups, group I received retrobulbar anesthesia and bridle suture, group II received retrobulbar anesthesia and group III received topical anesthesia.The measurement of interpalpebral fissure, levator function were taken at pre-op, post-op 1 week, post-op 4 weeks.The post operative mean palpebral fissure height and mean levator function decreased compared with those of the preoperative state but there were improvement of their ptosis with times.The incidence of ptosis at post operative 4 weeks was highest in group I with both retrobulbar anesthesia and bridle suture and lowest in group III with topical anesthesia (p=0.035).The result of this study indicate that ptosis after cataract surgery can be induced by various our operative techniques including retrobulbar anesthesia and bridle suture.We found there'll be many other causes of ptosis from the result of variant ptosis in group III with topical anesthesia.
