Study Arms (2)

Wavefront-guided LASIK

ACTIVE COMPARATOR

Wavefront-guided LASIK for myopia and myopic astigmatism

Procedure: Wavefront-guided LASIK

Topography-guided LASIK

ACTIVE COMPARATOR

Topography-guided LASIK for myopia and myopic astigmatism

Procedure: Wavefront-guided

Interventions

Topography-guided utilizes topography mapping to perform the ablation

Also known as: Topography-guided LASIK
Wavefront-guided LASIK

Wavefront-guided utilizes aberrometry to perform the ablation
