A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.

L'invention concerne un capteur à front d'ondes solidaire d'un microscope chirurgical, qui permet au docteur d'effectuer des mesures de front d'ondes répétées de l'oeil du patient, tandis que le patient reste sur une table d'opérations en position chirurgicale. Le dispositif comporte un capteur à front d'ondes optiquement aligné sur le microscope chirurgical de façon que leurs champs de vision se chevauchent au moins partiellement. L'inclusion de composants optiques de diffraction compacts et légers dans le capteur à front d'ondes permet au dispositif intégré d'être supporté sur un mécanisme d'équilibrage au-dessus de la tête du patient pendant l'opération chirurgicale. On élimine ainsi la nécessité de repositionner ledit dispositif et/ou le patient entre la mesure des propriétés optiques de l'oeil et l'exécution d'opérations chirurgicales sur l'oeil. Nombre d'opérations chirurgicales peuvent être améliorées ou renforcées au moyen du dispositif intégré, y compris, notamment, la chirurgie de la cataracte, la kératoplastie conductrice, la chirurgie lasik, et la chirurgie correctrice de la cornée.
