Hyperopic LASIK with corneal vertex centration minimizes postop higher-order aberrations
LASIK for high hyperopia with corneal vertex centration and asymmetric offset yielded a low risk of postoperative higher-order aberrations, according to a study.“Maintaining postoperative keratometry less than 49 D after hyperopic LASIK and centering on the corneal vertex reduces the induction of coma compared to non-aspheric profiles and lower hyperopia,” the study authors said. “The use of corneal vertex centration results in a morphologically stable cornea, less topographic asymmetry and enhanced stability.”
