title: The course of dry eye after phacoemulsification surgery.
abstract: BACKGROUND
  The aim of this retrospective study was to evaluate the course of dry eye syndrome after phacoemulsification surgery.
  
  
  METHODS
  One hundred and ninety-two eyes of 96 patients (30 males, 66 females) with chronic dry eye syndrome and cataract, who had undergone phacoemulsification surgery were enrolled in this study.
  
  
  RESULTS
  Their mean age was 68.46 ± 8.14 standard deviation (SD) (range 56-83) years . Thirty of them (31 %) were males and 66 (69 %) were females. Ocular Surface Disease Index (OSDI) questionnaire scores increased postoperatively, but arrived preoperative levels at the end of 3rd month following the surgery. Fluorescein staining patterns according to Oxford Schema got worse postoperatively, however after postoperative 3rd month they got better and resembled preoperative patterns. The mean postoperative 1st day, 1st week and 1st month Break-up Time (BUT) values were significantly lower than preoperative BUT value (P < 0.001, P < 0.001, P < 0.001), however 3rd month, 6th month, 1st year and 2nd year values were not significantly different from preoperative value (P = 0.441, P = 0.078, P = 0.145, P = 0.125). The mean postoperative 1st day, 1st week and 1st month Schirmer Test 1 (ST1) values were significantly lower than preoperative ST1 value (P < 0.001, P < 0.001, P < 0.001), however 3rd month, 6th month, 1st year and 2nd year values were not significantly different from preoperative value (P = 0.748, P = 0.439, P = 0.091, P = 0.214).
  
  
  CONCLUSIONS
  Phacoemulsification surgery may aggravate the signs and symptoms of dry eye and affect dry eye test values in chronic dry eye patients in short-term. However, in long-term, signs and symptoms of dry eye decrease and dry eye test values return to preoperative values.
