Objective  To evaluate long-term refractive outcomes of laser in situ keratomileusis （LASIK） for all levels of myopia. Methods  This was a retrospective case series study. One hundred twenty-five eyes of 68 patients who underwent LASIK for myopia and completed over 5 years of follow-up were included in the study. Based on the preoperative spherical equivalent refraction， the eyes were divided into 2 groups. Group A eyes ranged between -0.75 and -6.00 diopters （D） （mild-to-moderate myopia）. Group B eyes ranged between -6.12 and -13.25 D （severe myopia）. Before and at 1 month， 6 months， 1 year and 5 years after the operation， uncorrected visual acuity （UCVA）， best corrected visual acuity （BCVA）， slit-lamp biomicroscopy of the anterior segment，indirect ophthalmoscopy and topography were measured. At the time of the last follow-up， all patients completed a questionnaire assessing their satisfaction with the procedure. Data were analyzed using x² test and paired t test. Results  Uncorrected visual acuity ≥0.5 in groups A and B was obtained in 100% and 96% of eyes， and spherical equivalent refraction within ±1.00 D was obtained in 93% and 84% of eyes at 5 years. Spherical equivalent refraction in groups A and B was -0.021±0.65 D and -0.33±0.80 D， respectively， at five years. The differences compared with 1-year outcomes after the operation were not statistically significant. BCVA was unchanged or improved in 82% of all eyes （103/125）. Overall， only 1 epithelial ingrowth and 1 free partial flap were identified as complications from LASIK. Refraction did not regress in either group between 1 and 5 years. Late-onset complications attributable to LASIK were not observed at the 5-year follow-up， and patient satisfaction with the procedure was high. Conclusion  A long-term follow-up study of patients after undergoing LASIK for myopia shows it is a safe and effective procedure in correcting all levels of myopia. Complications were rare and patient satisfaction with the surgery was high. Refractive stability was maintained over the 5-year period. Late-onset complications attributable to LASIK were not noted.
