Patent ID: 8475439

Claim:
A surgical device for measuring properties of an eye, comprising: a surgical microscope providing a stereoscopic first field of view, the surgical microscope comprising a first housing and an objective lens; and a wavefront sensor for performing refractive measurements of the eye, the wavefront sensor providing a second field of view and comprising a different second housing the second housing comprising an optical passageway therethrough, and a combining optical element located in the second housing along the optical passageway, wherein the combining optical element is positioned to receive light that reflects from the eye and to send a first portion of the light reflected from the eye outside the second housing to the surgical microscope via the optical passageway through the second housing, and to send a second portion of the light reflected from the eye to one or more optical components within the second housing, wherein the second field of view of the wavefront sensor is optically aligned with the first field of view of the surgical microscope, wherein the wavefront sensor does not compromise the focal length of the surgical microscope, and wherein the wavefront sensor and the surgical microscope are not integrated with a laser for performing refractive correction on the eye.
