Patent ID: 7878655

Claim:
An intra-operative device used for examining an IOL implanted into a patient's eye, comprising: (a) a first optical layout having (a1) an illumination system configured to emit light; (a2) a beam splitter configured reflect light from the illumination system into a patient's eye and transmit light reflected from the patient's eye; (a3) an optical assembly configured as a wavefront sensor, the optical assembly configured to receive light transmitted through the beam splitter; and (a4) a first optical layout detector positioned to receive light outputted from the optical assembly; and (b) a second optical layout positioned along an optical axis of a patient's eye, the second optical layout comprising (b1) a light emitting diode (LED) annular lighting ring that emits tilted light rays with respect to the optical axis; (b2) an imaging optical system positioned along the optical axis; and (b3) a second optical layout detector positioned along the optical axis; wherein the imaging optical system is configured to image Purkinje images reflected from the patient's eye onto the second detector.
