Objective: This study aimed to compare contrast sensitivity status in dry eye patients before and after using sodium hyaluronate eyedrops.
Methods: This study is an experimental study. The subjects of the study were FK employees who were diligent, had corrected visual acuity of at least 6/12, were not using eye drops and were not taking routine medications. The examination carried out was vision with the best corrected visual acuity, contrast sensitivity using Pelli Robson and TFBUT (Tear Film Break Up Time). Data collection was carried out 2 times with a gap of 10 days, patients were asked to use NaHa eye drops 3 times daily. A total of 70 respondents were obtained. The data was analyzed using a 2x2 table (Fisher Test).
Results: The study was attended by 70 respondents, 65,7% were female. Majority of them have dry eye (58,6%) and most contrast sensitivity was normal (91,4%) even before the intervention. Using Fisher test, we compare the relationship between dry eye pre and post intervention, the results found to be no significan difference with p=0,584. We also compare the relationship between contrast sensitivity status with dry eye post intervention, the results were also no significant difference with p=0,656.
Conclusion: There were 12 dry eye respondents (17.1%) with improved contrast sensitivity after NaHa intervention. However, there was no significant difference in contrast sensitivity results either before or after the intervention
