Abstract | PURPOSE: METHODS: An interventional non-comparative study was performed on 50 consecutive patients with amblyopia treated with photorefractive keratectomy. Sixty-eight eyes of 18 participants with bilateral refractive amblyopia and 32 participants with unilateral anisometropic amblyopia were studied. The photorefractive keratectomy was performed with MEL 70 G-Scan excimer laser. Follow-up was 1, 3, 6, and 12 months after the treatment. The mean outcome measures were uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BCVA), refraction, and corneal transparency. RESULTS: In 64.7% of eyes, the UCVA at 12 months after the treatment was better than or equal to their preoperative BCVA. A total of 82.4% of eyes improved their BCVA one or more lines. No eye lost lines of BCVA, 17.6% remained unvaried, 50% gained one line, 20.6 % gained two lines, and 11.8% gained three lines of BCVA. The number of lines gained correlated strongly with diopters of anisometropia between eyes (p<0.01). The mean sphere changed from -5.62+/-3.37 D to -0.47+/-1 D, mean cylinder varied from -2.36+/-1.57 to -0.18+/-0.41 D, and the spherical equivalent varied from -6.82+/-3.1 to -0.45+/-1.08 D. No clinically significant haze was observed. CONCLUSIONS:
