Abstract:
Apparatus and methods are provided for interfacing an ophthalmic surgical laser with an eye using a patient interface (PI). The PI may include a closed, fluid-filled bladder having fiducials that contacts and deforms to the eye. Or, the PI may have an applanation lens with an outer ring portion and an inner concave portion for receiving the apex of the cornea. Another PI features a suction ring with a flexible skirt for contacting the sclera that is non-circular and/or non-planar. A system for injecting an index matching fluid into the area above the eye may also be incorporated. An integrated system includes a co-molded lens cone and attachment ring, with a lens window at the bottom of the lens cone which provides a sealed volume for vacuum-attaching a laser delivery system above the lens cone.
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.

Abstract:
A scanning lens component includes a primary and transverse axis stages and motors. The primary axis motor includes a first coil moving along the primary axis in the first direction along with the primary axis stage and a first magnet configured to move in a second, opposite direction, in response to movement of the first coil a first distance that exceeds a threshold primary axis distance. The transverse axis stage is adjacent and coupled to the primary axis stage and moves along a transverse axis in a third direction. The transverse axis motor includes a second coil for moving along the transverse axis in the third direction with the transverse axis stage, and a second magnet configured to move in a fourth, opposite direction, in response to movement of the second coil along the transverse axis in the third direction a second distance that exceeds a threshold transverse axis distance.
