Changes to Corneal Aberrations and Vision After PresbyLASIK Refractive Surgery Using the MEL 80 Platform

PresbyLASIK using the MEL 80 platform induced significant changes in spherical aberration in myopes and hyperopes. PresbyLASIK appears to offer an improved response over LASIK when correcting myopes due to an apparent increase in depth of focus resulting from changes in spherical aberration. For hyperopes, PresbyLASIK provides a more consistent spherical aberration effect independent of refractive change.
