Visual outcomes following customized laser in situ keratomileusis (LASIK) in myopic and hyperopic eyes with and without astigmatism

The use of wavefront-guided algorithms for treatment has increased over the past decade with estimates that up to 50 percent of all laser in situ keratomileusis (LASIK) procedures are now performed with this approach1. Although originally intended to correct higher order aberrations, the use of wavefront-guided algorithms, particularly those with iris-registration and tracking, have been shown to benefit patients with lower order aberrations (sphere and cylinder)2,3. This is likely due to the fact that no or fewer higher order aberrations are induced during the procedure4. In the study presented here, we used a wavefrontguided algorithm (CustomVue) with iris registration to treat myopic and hyperopic patients, with and without
