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.

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.
