1. A system for intraoperatively measuring tilt of an implanted intraocular lens, the system comprising: a wavefront sensor capable of being integrated with a surgical microscope for interoperatively viewing an eye of a patient, the wavefront sensor further comprising: a ring of a plurality of light sources to direct light toward an implanted intraocular lens within the eye; a lens and a detector to: receive reflected light originating from the plurality of light sources and reflected by at least the implanted intraocular lens; and generate image data indicative of the reflected light; and a processor having access to memory media storing instructions executable by the processor to: receive the image data from the detector; and calculate tilt of the implanted intraocular lens based on locations of Purkinje images identified in the image data.
