The human eye may be able to self-adjust and partially compensate for optical aberrations caused by LASIK eye surgery, according to a new study. LASIK, PRK and other corneal refractive surgery have been shown to increase higher-order aberrations in the eye that can affect visual clarity. Even customized, wavefront-guided LASIK typically increases these aberrations to some extent.

Eye may adjust to aberrations caused by LASIK
June 8, 2010Wavefront-guided LASIK induces fewer higher-order aberrations than wavefront-optimized LASIK
June 1, 2009A recent study finds wavefront-guided LASIK induces fewer higher-order aberrations than a related customized laser vision correction procedure called wavefront-optimized LASIK. Typically, fewer higher-order aberrations means better visual outcomes after LASIK surgery. The study suggests wavefront-guided LASIK offers the best results for most patients, with a lower incidence of re-treatments.
