Abstract | OBJECTIVE: METHODS: This is a prospective and self-control study which included 42 children with high hyperopic anisometropic amblyopia. The age of the children ranged from 6 to 14 years. LASIK was performed in the eyes with higher degree of hyperopic under topical or general anaesthesia using the Summit's SVS Apex plus (L mask for simple hyperopia, 9 eyes; P mask for hyperopia and astigmatism, 12 eyes) and the Lumenis's Allegretto Wave (21 eyes). Postoperative visual acuity, refraction and the binocular vision were analyzed. Minimum follow-up period was 6 months; 24 children had a 2-year follow-up. RESULTS: In eyes with +3.00 diopters (D) to +7.50 D preoperatively, the postoperative refraction in 66.6% of eyes was within +/- 1.00 D of the expected correction. From 6 to 24 months postoperatively, there was a mean variation from +0.67 to + 0.99 D in cycloplegic equivalent refraction. Best spectacle-corrected visual acuity (BSCVA) of distance and reading did not decrease after the surgery. The mean BSCVA of distance was 0.40 +/- 0.28 (P < 0.001) and reading BSCVA was 0.78 +/- 0.39 (P < 0.001) 2 years after the surgery. Simultaneous vision, fusion, stereopsis and heterophoria were improved 2 years postoperatively. CONCLUSIONS:
LASIK is a safe and effective procedure for the correction of high hyperopic anisometropia in children who cannot tolerate contact lens. This procedure provides a satisfactory predictability and refractive stability results 2 years postoperatively. The effects of amblyopia therapy can be improved after the surgery.
