Patent ID: 8556885

Claim:
A system for aligning a laser refractive correction instrument with a patient's eye comprising: a refractive diagnostic tool adapted to provide refractive data about the patient's eye, wherein the refractive diagnostic tool comprises: a first camera adapted to acquire a first iris image of the patient's eye, wherein the refractive diagnostic tool is also adapted to spatially relate iris data representing the first iris image to said refractive characteristic data; and a laser system adapted to apply a course of refractive treatment to the patient's eye, wherein the laser system comprises: a second camera adapted to acquire a second iris image of the patient's eye, a laser adapted to apply the course of refractive treatment, and a control system for initiating the course of refractive treatment, the control system being adapted to receive data derived from the refractive characteristic data and the spatially related iris data and to align the iris data to the second iris image before the control system initiates the course of refractive treatment.
