Purpose To evaluate the visual outcomes of patients with anisometropic amblyopia after laser in-situ keratomileusis (LASIK) surgery. Patients and methods LASIK was performed in 24 anisometropic amblyopic eyes of 24 patients. All eyes were amblyopic and received the standard amblyopia treatment (occlusion and/or optical penalization). The mean age of the patients was 21.62 ± 9.55 SD years, ranging from 6 to 42 years. The mean myopic error ± SD was -5.7 ± 2.25 (range from −11.5 to −3.25) and the mean hypermetropic ± SD was +3.5 ± 0.95. Results The preoperative mean uncorrected visual acuity ± SD was 0.11 ± 0.06 and became 0.56 ± 0.18, whereas the preoperative mean best corrected visual acuity was 0.39 ± 0.13 and became 0.57 ± 0.17 6 months postoperatively. Uncorrected visual acuity of all patients improved significantly about three or more lines in Snellen's chart. The best corrected visual acuity of about 79% of the patients improved by one or more lines in Snellen's chart. Conclusion LASIK is an effective option for the correction of high myopic or hypermetropic anisometropia. Recommendations LASIK surgery could be recommended in all types of anisometropic amblyopic patients in whom traditional management failed and who were intolerable to glasses or contact lenses. Amblypoia management should be continued postoperatively. Further studies are recommended to assess factors affecting anisometropic amblyopia management by LASIK, such as age, refraction, depth of amblyopia and response to conventional therapy.
