Abstract

PURPOSE

To compare astigmatic outcomes between eyes having wavefront-guided laser in situ keratomileusis (LASIK) and eyes having wavefront-guided photorefractive keratectomy (PRK).

SETTING

Byers Eye Institute, Stanford University School of Medicine, Palo Alto, California, USA.

DESIGN

Prospective randomized case series.

METHODS

Patients had refractive surgery, with one eye treated with LASIK and the other treated with PRK. Eyes were randomized according to ocular dominance. Astigmatism vectors were evaluated using the Alpins vector analysis of astigmatism.

RESULTS

Thirty-four patients (68 eyes) had vector analysis; the LASIK and PRK groups had similar target-induced astigmatism vectors (P = 0.75), surgically induced astigmatism vectors (P = 0.86), difference vectors (P = 1.0), indices of success (P = 0.4), correction indices (P = 0.28), and flattening indices (P = 0.5).

CONCLUSION

Based on Alpins vector analysis of astigmatism, there were no statistically significant differences between eyes that had LASIK and eyes that had PRK.
