    Abstract:
    PURPOSE: To assess the changes in intraocular scattering before and after instillation of rebamipide ophthalmic suspension in patients with dry eye after corneal refractive surgery. METHODS: This study enrolled 60 eyes of 30 dry eye patients undergoing corneal refractive surgery. Patients were randomly assigned to start topical administration of rebamipide ophthalmic suspension (rebamipide group) or artificial tears (control group) 4 times daily for 4 weeks. Tear secretion, tear break-up time (TBUT), and the fluorescein score were measured before and after treatment. Intraocular light scattering was also measured as the objective scattering index (OSI) at 0.5-second intervals over 10 seconds. RESULTS: In the rebamipide group, the Schirmer I test, TBUT, and fluorescein score improved significantly, from 11.4 ± 9.0 mm, 2.2 ± 0.7 seconds, and 4.3 ± 1.3 to 14.9 ± 7.4 mm, 4.5 ± 1.7 seconds, and 1.9 ± 1.0, respectively (P = 0.006, P < 0.001, P < 0.001, Wilcoxon signed rank test). We found significant improvements in OSI at 5.0 to 10.0 seconds after blinking (5-8 seconds, P = 0.01; 9 seconds, P = 0.02; 10 seconds, P < 0.001). The mean OSI, the OSI change rate, and the OSI slope of the linear regression line improved significantly, from 2.73 ± 1.52, 74.7 ± 69.5%, and 0.10 ± 0.12 to 2.19 ± 1.19, 28.6 ± 48.7%, and 0.04 ± 0.08, respectively (P = 0.02, 0.003, and 0.03). CONCLUSIONS: Rebamipide ophthalmic suspension was effective for improving both ocular surface parameters and optical quality in patients with dry eye undergoing corneal refractive surgery, suggesting that it may hold promise for the treatment of such patients.
