Analysis of dry eye syndrome incidence and prognostic factors in 778 patients following refractive corneal surgery

Dry eye syndrome exhibits a relatively high incidence following refractive corneal surgery. Female gender, surface ablation procedures, and compromised preoperative tear film function constitute independent risk factors for postoperative dry eye development. Systematic preoperative assessment of tear film function is essential, with proactive intervention and individualized surgical planning recommended for high-risk patients to reduce postoperative dry eye incidence and enhance patient satisfaction.
