title: Clinical analysis of tear film after lamellar keratoplasty.
abstract: OBJECTIVE
  To study the tear film stability after lamellar keratoplasty.
  
  
  METHODS
  Five female and eight male patients with lamellar keratoconus, aged from 18 to 32, were involved. After lamellar keratoplasty, Schirmer I test(S I t), tear break-up time(BUT) test, fluorescein staining test were used to judge the effect of the surgery at different time point.
  
  
  RESULTS
  The S I t were greatly increased in 7 days post operation (11.86±2.28 -25.14±1.97, 19.86±1.61) (P<0.05), there is no significant difference between 2(nd) month, 3(rd) month post-operative and pre-operation (11.86±2.28 - 14.57±1.48, 8.14±0.86) (P>0.05). The mean break-up time decreased in 7 days post operation (5.00±1.31 - 2.71±0.18, 2.57±0.20, 2.71±0.36, 2.43±0.20) (P<0.05). The mean scores of fluorescence increased post-operatively (0.14±0.14 - 8.00±0.00, 8.00±0.00, 8.00±0.00, 7.57±0.20) (P<0.01).
  
  
  CONCLUSIONS
  Lamellar keratoplaty influence the tear film stability, artificial tears and improving corneal epithelium cured medicine should be used after surgery.
