title: [Postoperative ptosis after cataract extraction: own material].
abstract: OBJECTIVE
  To determine the incidence of postoperative ptosis in patients after cataract extraction and whether the type of local anaesthesia has any influence on the occurrence of this complication.
  
  
  METHODS
  This study comprised 72 patients who had phakoemulsification of cataract. In group I 36 patients received 2-point peribulbar anaesthesia and in group II 36 patients received retrobulbar anaesthesia and the lid block. No bridle suture was used in both groups. To evaluate the ptosis the distance between the upper lid margin and central corneal reflex was measured before and 3 days after the operation.
  
  
  RESULTS
  The ptosis of 2 mm occurred in one patient. There was no statistical difference between two groups referring to the incidence of ptosis.
  
  
  CONCLUSIONS
  This relatively low incidence may be due to not using bridle suture. The technique of anaesthesia seemed to have no influence on the incidence of postoperative ptosis in our study.
