Wavefront-optimized excimer laser in situ keratomileusis for myopia and myopic astigmatism: refractive outcomes and corneal densitometry.

Purpose: To determine the refractive outcomes of wavefront-optimized laser in situ keratomileusis (LASIK) treatments, in particular to measure corneal densitometry after LASIK using the densitometry function of the Pentacam Scheimpflug system.

Setting: Division of Ophthalmology and Visual Sciences, University of Nottingham, United Kingdom.

Design: Cohort study.

Efficacy, predictability, and safety of wavefront-guided refractive laser treatment: metaanalysis.

Purpose: To compare the efficacy, predictability, safety, and induced higher-order aberrations (HOAs) between wavefront-guided and non-wavefront-guided ablations.

Setting: Division of Ophthalmology and Visual Sciences, University of Nottingham, Nottingham, United Kingdom.

Design: Metaanalysis.
