Methods and systems can correct aberrations and/or verify various procedures used to correct aberrations in the eye. One embodiment provides a method for verifying vision correction for a patient's eye comprising measuring irregular aberrations of the eye and determining a proposed refractive correction for treatment of the eye. A central portion of a verification lens is configured so that the central portion corresponds with the proposed correction. The verification lens is then registered with the eye by positioning a peripheral portion of the verification lens upon the sclera so that the central portion is optically aligned with the aberrations. Then a determination is made whether a corrected vision of the eye with the verification lens is acceptable so as to verify the proposed correction.

L'invention concerne des procédés et des systèmes pour corriger des aberrations et/ou vérifier différents procédés pour corriger des aberrations de l'oeil. Dans un mode de réalisation, un procédé permet de vérifier une correction visuelle sur l'oeil d'un patient, ce procédé consistant à mesurer les aberrations irrégulière de l'oeil et à déterminer une proposition de correction réfractive pour traiter l'oeil. Une partie centrale d'une lentille de vérification est conçue pour correspondre à la correction proposée. La lentille de vérification est alors enregistrée avec l'oeil en plaçant une partie périphérique de ladite lentille de vérification sur la sclère de sorte que la partie centrale est optiquement dans la ligne des aberrations. On détermine alors si une vision corrigée de l'oeil est acceptable pour vérifier la correction proposée.
