DIFFERENCES IN OCULAR SURFACE DISEASE INDEX SCORE IN PATIENTS BEFORE AND AFTER COMBINATION OF PHACOEMULSIFICATION AND TRABECULECTOMY.

AbstractBackground: Dry eye is a disturbance on the surface of the eyeball marked by the loss of tear layer homeostasis, which can occur due to the instability and hyperosmolarity of tear film, inflammation or damage to the surface of the eyeball, and neurosensory abnormalities. Some surgical interventions related to the anterior part of the eye can cause symptoms of dry eye, one of which is facotrabeculectomy is a combination of surgical intervention performed in glaucoma patients with cataracts. One examination to evaluate the symptoms of dry eye is to use the Ocular Surface Disease Index (OSDI) questionnaire.Objective: This study aims to observe the difference in Ocular Surface Disease Index (OSDI) scores in patients before and after surgery combined with phacoemulsification and trabeculectomy.Methods: Analytic observational research with one group pretest and posttest research design. With a large sample of 18 respondents who were evaluated by the OSDI questionnaire in patients before and two weeks after facotrabeculectomy. Hypothesis testing with a paired T-test.Results: The results showed that before the surgery for facotrabeculectomy, the average OSDI score was 50.4628 ± 7.9429. After two weeks postoperatively the results of the study showed the average OSDI score was 58.7972 ± 7.7155. Hypothesis testing showed that OSDI scores before and after facotrabeculectomy surgery were significant differences (p = 0.001 / p <0.05).Conclusion: There were significant differences in OSDI scores in patients before and after facotrabeculectomy surgery.
