PURPOSE. To evaluate the visual and refractive outcome in adult patients with refractive and anisometropic amblyopia treated with photorefractive keratectomy. 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. Excimer laser refractive surgery appears to be a safe and efficient procedure in the treatment of ametropic and anisometropic amblyopia in adults. Adult patients with anisometropic and refractive amblyopia could benefit from the refractive treatment with significant improvement of the visual acuity.
