Primary Outcome Measures

Name	Time	Method
Change in subjective symptoms of dry eye disease. The subjective symptoms were graded using ocular surface disease index (OSDI) score (0 to 100), with higher scores representing greater disability. The patients answered the 12 items on the OSDI questionnaire that were graded on a scale of 0 to 4 (0: none of the time, 1: some of the time, 2: half of the time, 3: most of the time, 4: all of the time). The OSDI was calculated by ([sum of scores for all questions answered]×100)/([total number of questions answered]×5). The OSDI score was evaluated at baseline, 4 weeks, and 8 weeks after treatment.

Secondary Outcome Measures

Name	Time	Method
1. Tear film break up time - the time before the defect of fluorescein dye appeared in the stained tear film was measured and recorded (measured TBUT 3 times and averaged)<br>2. Schirmer’s test (with anesthesia)<br>Both evaluated at baseline, 4 weeks, and 8 weeks after treatment.
