Abstract
Currently there is considerable interest in correcting the higher-order optical aberrations of the human eye [1]. Present-day laser eye surgery techniques like PRK and LASIK correct only defocus and astigmatism, which are 2nd order aberrations. Surgically correcting the additional higher-order aberrations could extend the limits of human vision beyond 20/20. In addition, this type of capability could be used to eliminate the higher-order aberrations that may have been caused by a prior surgical procedure. These induced aberrations are responsible for the glare, halos, and other visual defects that have been reported by some eye surgery patients.
