Abstract
A system and method for performing ophthalmic surgery using an ultra-short pulsed laser is provided. The system includes a laser engine configured to provide an ultra-short pulsed laser beam, optics configured to direct the laser beam to an undocked eye of a patient, an eye tracker configured to measure five degrees of freedom of movement of the undocked eye, an optical coherence tomography module configured to measure depth of the undocked eye, and a controller configured to control laser beam position on the undocked eye toward a desired laser pattern based on depth and the five degrees of freedom of movement of the undocked eye. Adaptive optics are also provided. Also disclosed are a scleral ring including fiducial markings and a compliant contact lens and fluid tillable contact lens configured to facilitate ultra-short pulsed laser surgery while reducing or eliminating eye docking requirements.
