Visual outcomes of wavefront-guided laser in situ keratomileusis in eyes with moderate or high myopia and compound myopic astigmatism.
OBJECTIVE
To evaluate the safety, efficacy, and clinical outcomes of wavefront-guided laser in situ keratomileusis (LASIK) surgery for the treatment of moderate to high myopia and compound myopic astigmatism.


METHODS
Stanford University School of Medicine, Department of Ophthalmology, Stanford, California, USA.


METHODS
This retrospective study included patients with moderate (-6.0 to -8.0 diopters [D]) and high (greater than -8.00) myopia treated with wavefront-guided LASIK using the WaveScan linked to the CustomVue system (AMO USA, Inc.). Eyes were analyzed preoperatively and 1, 3, and 12 months postoperatively.


RESULTS
The mean patient age was 38.4 years +/- 7.14 (SD). Eighty-nine eyes of 45 patients were evaluated at 3 months and 50 eyes of 25 patients at 12 months. No eye was retreated during the study. The mean manifest refraction spherical equivalent was -8.10 +/- 0.98 D (range -6.00 to -10.63 D) preoperatively and -0.33 +/- 0.55 D (range -1.625 to 1.375 D) 12 months postoperatively. Ninety percent of the eyes were within +/-1.00 D of the intended correction and 64.0%, within +/-0.50 D. For all eyes, the safety index was 1.00 and the efficacy index, 1.18.


CONCLUSIONS
The data support the safety and efficacy of correcting moderate to high myopia and compound myopic astigmatism using wavefront-guided LASIK.
