Higher Order Aberrations in Normal, Dilated, Intraocular Lens, and Laser in situ Keratomileusis Corneas

Abstract

Both IOL and LASIK surgery elevate spherical aberration and wavefront variance, with increasing magnitude of effect with increasing pupil size, although pupillary dilation alone did not produce statistically different changes, as compared to normal subjects. These findings demonstrate that IOL implantation can produce more net aberrations than LASIK, and demonstrate a new opportunity to optimize surgical results.
