Visual Acuity After Laser In Situ Keratomileusis to Correct High Astigmatism in Adults with Meridional Amblyopia

Purpose To analyze the effect of laser in situ keratomileusis to correct high myopic astigmatism in patients with suboptimal best spectacle-corrected visual acuity (BSCVA). Design Retrospective, interventional series of consecutive cases. Methods setting: Vissum Madrid, Madrid, Spain. patients: Two hundred five eyes of consecutive patients with suboptimal BSCVA and high myopic astigmatism of −3 diopters or more. intervention: Laser in situ keratomileusis surgery. main outcome measures: BSCVA. Results The BSCVA (decimal Snellen fraction notation) improved significantly ( P = .0001) from a mean preoperative 0.77 ± 0.18 (range, 0.05 to 0.90) to 0.81 ± 0.19 (range, 0.05 to 1.25) 3 months after surgery. The mean change in lines of BSCVA (decimal Snellen fraction notation) was 0.04 ± 0.11 (range, −0.25 to 0.4). A significant inverse relationship ( P = .001) was found between the preoperative BSCVA and the improvement in BSCVA. Conclusions In eyes with high myopic astigmatism and suboptimal preoperative BSCVA, laser in situ keratomileusis may result in a significant improvement in BSCVA.
