Efficacy Of Using Cationorm and Systane Eye Drops on Post-Lasik Dry Eye

LASIK is famous procedure for correcting refractive errors. The post-LASIK dry eye is very common. Systane and cationorm eye drops are good for post-LASIK dry eye. Objectives: To evaluate and compare the efficacy of Cationorm and Systane eye drops and assess the effect on asthenopic symptoms post-LASIK dry eye. Methods: A Qusai experimental study design was used. This study included 80 patients with the age of 20 to 35 years. Data were collected at Al Qasim Eye Care. 40 patients were treated with cationorm; and other were treated with Systane on post-LASIK dry eye. After using cationorm and systane eye drops assessment of dry eye was measured by TBUT. Patients came for follow ups at 2nd day, 15th day and 1 month after the LASIK procedure was done. Statistical analysis was done by applying Mann Whitney U test, Friedman’s two-way test, Cochran’s test and chi square test. Results: The mean value and standard deviation of Systane and cationorm eye drop recorded at the baseline were 10.00, ± 0.00, 10.00 ± 0.00, after 2nd day it was 8.08 ± 1.163, 8.48 ± 0.987, after 15 days 8.93 ± 2.485, 12.30 ± 1.713, and 1 month 9.05 ± 2.417, 12.93 ± 1.745 respectively. There was a significant effect on post-LASIK dry eye after using Systane and Cationorm eye drop with p<0. 001.Comparison of systane and Cationorm eye drops with asthenopic symptoms on post-LASIK dry eye showed cationorm is better than the systane eye drops. Conclusions: Cationorm showed more significant results as compared to systane eye drops and cationorm gave faster relief from asthenopic symptoms on post-LASIK dry eye
