LASER EYE SURGERY SYSTEM
First Claim
1. A laser eye surgery system, comprising:
- a laser source configured to produce a treatment beam that includes a plurality of laser pulses;
a ranging subsystem configured to produce a source beam used to locate one or more structures of an eye, the ranging subsystem includes an optical coherence tomography (OCT) pickoff assembly that includes a first optical wedge and a second optical wedge separated from the first optical wedge, the OCT pickoff assembly being configured to divide the source beam into a sample beam and a reference beam;
an integrated optical subsystem configured to receive the treatment beam, direct the treatment beam to selected treatment locations within the eye so as to incise tissue at the selected treatment locations, receive the sample beam, direct the sample beam to selected measurement locations within the eye, and transmit return portions of the sample beam from the selected measurement locations back to the ranging subsystem for processing by the ranging subsystem; and
a patient interface assembly configured to couple the eye with the integrated optical subsystem so as to constrain the eye relative to the integrated optical subsystem.

Abstract
A laser eye surgery system includes a laser source, a ranging subsystem, an integrated optical subsystem, and a patient interface assembly. The laser source produces a treatment beam that includes a plurality of laser pulses. The ranging subsystem produces a source beam used to locate one or more structures of an eye. The ranging subsystem includes an optical coherence tomography (OCT) pickoff assembly that includes a first optical wedge and a second optical wedge separated from the first optical wedge. The OCT pickoff assembly is configured to divide an OCT source beam into a sample beam and a reference beam. The integrated optical subsystem is used to scan the treatment beam and the sample beam. The patient interface assembly couples the eye with the integrated optical subsystem so as to constrain the eye relative to the integrated optical subsystem.
