Objective To evaluate the safety, efficacy, predictability, and stability of excimer laser in situ keratomeleusis (LASIK) for anisometropia of high myopia in children. Methods LASIK was performed in 25 eyes of 25 patients (15 boys and 10 girls, age ranged from 7 to 15 years old) with high anisometropia. The follow up time was at least 12 months. Results The mean of the preoperative spherical refraction, the mean of the preoperative cylindrical refraction, the mean of the preoperative uncorrected visual acuity, and the mean of the preoperative corrected visual acuity were (-9.31±3.33) D and (-4.50 - -17.25) D, (-1.35±0.47) D and (-1.25 - -4.50) D, (0.08±0.04) and (0.04-0.1), and (0.46±0.31) and (0.1-1.0), respectively. At 12 months after surgery, the mean of the spherical refraction, the mean of the cylindrical refraction, the mean of the uncorrected visual acuity, and the mean of the best corrected vision acuity were (-1.11±1.17) D and (+0.50 - -3.25) D, (-0.10±0.14) D and (+0.25 - -1.25) D, (0.57±0.41) and (0.2-1.0), and (0.69±0.40) and (0.3-1.2) D, respectively. Conclusion The technology of LASIK for anisometropia of children with high myopia is safe, effective, predictable, and stable. LASIK is an effective option for correction of anisometropia when conventional therapies are not adaptable.
