The Association Between Spectacle Correction, Ocular Surface Health and Visual Function in Patients with Myopia and Coexisting DED

Objective: To evaluate the impact of regular refractive correction (spectacle wear) on dry-eye-related parameters and binocular visual function in myopic adults with coexisting dry eye disease(DED). Methods: A cross-sectional observational study enrolled 120 myopic patients with DED , divided into a refractive correction group (n=68) and a non-correction group (n=52) based on daily spectacle wear duration. Dry eye parameters including tear meniscus height (TMH) and average tear break-up time (ave TBUT), binocular visual function parameters Results: The refractive correction group showed significantly longer ave TBUT and lower OSDI scores (P<0.05), with no significant TMH difference. Visual function was better in the correction group, with significantly lower PRA, higher NRA, and greater monocular/binocular AF (all P<0.05). Ave TBUT was negatively correlated with PRA and positively correlated with NRA and AF (P<0.05); TMH showed no significant correlations. Conclusion: Regular spectacle wear is associated with improved tear film stability, reduced dry-eye symptoms, and enhanced binocular visual function in myopic patients with dry eye.
