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. 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.
