Objective To comprehensively evaluate the long-term efficacy, visual quality, and safety of excimer laser corneal refractive surgery for correcting refractive errors, and to compare the indications and clinical value of different surgical procedures. Methods A prospective cohort study design was used to select 1800 patients (1800 eyes) who underwent surgery between January 2023 and June 2025. They were divided into Trans PRK group (Group A, n=600), LASIK group (Group B, n=600), and LASEK group (Group C, n=600) according to the surgical method. Compare the visual acuity recovery, refractive stability, and changes in corneal biomechanical properties among three groups of patients one year after surgery. Results One year after surgery, the proportion of UCVA ≥ 1.0 and SE within ± 0.50D in the three groups was 90.67% in group A, 91.16% in group B, and 88.33% in group C. Group B was slightly better than group C (P=0.038), while there was no significant difference between group A and group B (P=0.667). Conclusion Excimer laser corneal refractive surgery is a safe and effective method for correcting refractive errors, among which LASIK has the fastest visual recovery after surgery, Trans PRK has better biomechanical stability, and LASEK is suitable for specific thin corneal patients. Personalized surgical procedure selection, strict preoperative evaluation, and standardized procedures are key factors in ensuring surgical success.
