Precorneal tear film was altered in pterygium eye and may be improved after pterygium removal. To compare Schirmer's test results and tear breakup time before and after pterygium surgery. Forty patients, aged between 30 and 77 years were enrolled in this study; one pterygium surgery eye was observed per patient. A paired t-test was used to compare Schirmer's test results and tear breakup time pre pterygium excision and one-month post-operation. There were no statistically significant differences in Schirmer's test results and tear breakup time between pre and one-month post-operation. The mean +/- standard deviations of Schirmer's test results before and one-month after pterygium surgery were 9.2 +/- 4.3 and 10.0 +/- 6.3 millimeters, respectively (p = 0.30), and those results for tear breakup time were 7.5 +/- 3.0 and 7.9 +/- 3.1 seconds, respectively (p = 0.44). Pterygium removal may not have any effect on Schirmer's test results and tear breakup time one-month post- surgery.
