Abstract: An electro-optical patternable mask is provided which is controllable by way of a processor for presenting a variety of patterns to electromagnetic radiation. In one embodiment of the mask, the electro-optical mask includes an electrochromic layer that works in conjunction with deposited electrode layers (at least one with an x-y pixel array) to present a pattern of non-transmission (colored) and transmission (bleached clear) pixel cells. The sandwiched electrochromic material is supported in one embodiment with a UV grade support substrate with the electrochromic cells of the mask being individually (e.g., individual cells or small groups of individual cells in an array) controlled by a processor and interface to achieve a sequence of different or the same patterns to achieve desired ablation volume upon transmitting ultraviolet energy through the mask such as in conjunction with an opthalmic laser surgery process.

Abstract: A system and method particularly suited for controlled ablation of the cornea, using ultraviolet laser radiation, with the cornea sculpturing action resulting from a computer driven digital programmed distribution of excimer flux density across a controllable liquid crystal matrix mask to achieve a desired volume and shape of ablation for the correction of the curvature of the cornea. The optical mask, in one embodiment, is based on an arrayable matrix of individual optical pixel cells with two optical states between fully transparent to fully opaque or mirror like to the UV light. The system provides a highly versatile system for correcting known corneal defects in both regular and irregular corneas by simply executing computer customized patterns in very short time and with great precision and detail.

Abstract: An eye laser system which includes a laser and a laser delivery system for delivering a laser beam generated by the laser to the eye and an eyetracking system which monitors movement of the eye and conveys eyetracking information to the laser delivery system with the eyetracking system including a non-invasive eye tilt reference marker. The reference marker projects an energy beam that is preferably visible so as to reflect off the iris of the eye and provide microscope and surgical field illumination. The reference marker includes a plurality of points arranged concentrically about the pupil of the eye and/or a concentric ring marking device. This arrangement provides information as to eye tilt for use in, for example, video frame review during an initial reference setting or a subsequent eye tracking stage.
