Aim: =o know the influence of small incision cataract surgery on tearfilm by measuring dryness symptoms using ocular surface disease index (OS7I) score and Euantify changes in tear film using tear meniscus height,schirmers test 1, =GD=, Fluorescein staining , impression cytology. Materialandmethod: A prospective descriptive study was conducted among 180 patient undergoing small incision cataract surgery in department of ophthalmology, NM8F Raichur. .esults: Out of 180 patient, =he mean age group was :;.87R9.:0 years.Mean value of pre- operative vspost operative 1st,Ard,;th week for OS7I was11.274,21.9A2, 18.880,1:.A7; respectively. schirmers 1 test showed mean21.7::,12.A22, 1:.7A8,17.01;. =GD= values were 12.;89,7.922,8.400,9.9;1 respectively . =ear meniscus height mean score were 0.A01, 0.21:, 0.1;1,0.212 respectively.mean value of impression cytology showed 7A2.0:R2A2.4; and A:;.A;R107.1; cells / mm2.. . Oxford scheme grading showed grade 1 in pre operative period and grade 1 ,2 ,1 in post operative followup for 1st, Ard, ;th week respectively. Conclusion: A significant number of patient with no dryness symptom before cataract surgery developed tear film abnormalities in immediatepost operative periodstudies with longer time period are recommended to assess time taken for tear film to recover to pre operative state. In addition to this patient also needed to be started on lubricating drops intensively prior to surgery for patient comfort post operatively.
