Abstract

Background: Dry eye syndrome is a common condition following cataract surgery, with various influencing factors and manifestations. Objective: To determine the prevalence, morphological characteristics, and treatment outcomes of dry eye after cataract surgery. Materials and methods: A cross-sectional descriptive study of 479 eyes after cataract surgery at Can Tho City General Hospital from August 2023 to December 2023. Results: 150 out of 479 eyes (31.31%) developed dry eye with the following morphological forms: Area (23.33%), Spot (22%), Line (34%), Dimple (7.33%), and Random (13.33%). The severity of dry eye increased on the first day postsurgery and continued for the next two weeks. Risk factors associated with dry eye included age (mean 65.88±8.9 years; 119/150 cases >60 years), female gender (83/67), cataract density (grades 3,4; 80%), and certain surgery-related factors. The OSDI (Ocular Surface Disease Index) increased on the first day post-surgery, with a mean of 68.16±10.01, compared to pre-surgery at 42.19±10.92. The tear breakup time (TBUT) decreased post-surgery, with a mean of 2.89±2.72 seconds. Initial treatment results showed that the group using Diquafosol 3% achieved an efficacy rate of 98.53%, while the group using Hyaluronate 0.1% had a 97.56% efficacy rate, with TBUT and OSDI indices trending toward normal in the following weeks.Conclusion: Dry eye syndrome is prevalent after cataract surgery, affecting approximately one-third of patients, with all five forms of tear breakup represented, and the line form being the most common. Treatment was effective in 98% of cases, with the remaining 2% showing limited symptom improvement or non-compliance with treatment.
