Abstract

The field of the invention relates to systems and methods for ophthalmic laser procedure and, more particularly, to systems and methods for dynamic fixation used in the fixation of the eye(s) of a patient during laser-assisted ophthalmic surgery and/or ophthalmic diagnostic and measurement systems where visualization and concentration on a target are desired. The invention generally enhances the alignment between the eye and a laser beam of a laser eye surgery system using visual fixation system and laser delivery optics. The visual fixation system allows a patient's eye(s) to be accurately focused at one or more fixation targets.

First claim

What is claimed is:

1. An ophthalmic laser-based treatment system comprising:
a laser delivery system for delivering a pulsed laser beam to an eye;
an eye fixation system positioned proximate to the laser delivery system and configured to cause the eye to be fixated at a desired position, the eye fixation system including one or more light sources generating one or more light beams which are different from the pulsed laser beam, wherein the laser delivery system delivers the one…
