In one aspect, the present invention provides a method of designing an ocular implant (e.g., an IOL), which comprises establishing corneal topography of a patient's eye, e.g., by performing one or more wavefront aberration measurements of the eye, prior to an ocular surgery. The method further includes ascertaining an astigmatic aberration of the cornea that is expected to be induced by the surgery and determining a toricity of a surface of an ocular implant, which is intended for implantation in the patient's eye, so as to enable the implant to compensate for the surgically-induced aberration.
Dans un aspect, la présente invention concerne un procédé de conception d'un implant oculaire (par exemple, une lentille intraoculaire), qui comprend l'établissement de la topographie cornéenne de l'AEil d'un patient, par exemple, en réalisant une ou plusieurs mesures de l'aberration du front d'onde de l'AEil, avant une chirurgie oculaire. Le procédé comprend en outre la vérification d'une aberration astigmatique de la cornée que l'on suppose induite par la chirurgie et la détermination d'une forme torique d'une surface d'un implant oculaire, qui est prévu pour être implanté dans l'AEil du patient, de sorte que l'implant compense l'aberration induite par la chirurgie.
