## Abstract

A compact system for performing laser ophthalmic surgery is disclosed. An embodiment of the system includes a mode-locked fiber oscillator-based ultra-short pulsed laser capable of producing laser pulses in the range of 1 nJ to 5 μJ at a pulse repetition rate of between 5 MHz and 25 MHz, a resonant optical scanner oscillating at a frequency of 200 Hz and 21000 Hz, a scan-line rotator, a movable XY-san device, a z-scan device, and a controller configured to coordinate with the other components of the system to produce one or more desired incision patterns. The system also includes compact visualization optics for in-process monitoring using a beam-splitter inside the cone of a patient interface used to fixate the patient's eye during surgery. The system can be configured such that eye surgery is performed while the patient is either sitting upright, or lying on his or her back.

## Claims

### Claim 1

An interface for coupling a patient's eye to an ophthalmic surgical laser system, the interface comprising:
a lens cone defining a first plane surface coupled with a delivery tip of the ophthalmic laser system;
one or more beam-splitter optics within the lens cone configured to allow a pulsed laser beam to pass through the interface to a focal point of the target in the patient's eye and to reflect light from the patient's eye; and
a side-imaging optical channel joined to the lens cone and configured to receive light reflected from the one or more beam-splitter optics and reflect the light to exit the interface, wherein the lens cone has a circular shape in a top view that is viewed along a rotational axis of the lens cone, and wherein the side-imaging optical channel is a protruding portion that protrudes from the lens cone in the top view,
wherein the lens cone, the one or more beam-splitter optics and the side-imaging optical channel are fixed to the ophthalmic surgical laser system and configured to rotate, while fixed to the ophthalmic surgical laser system, relative to the ophthalmic surgical laser system to a temporal side of the patient's eye.

### Claim 2 (depends on 1)

The interface of claim 1, wherein the one or more beam-splitter optics comprises one or more multi-facet beam-splitter optics.

### Claim 3 (depends on 1)

The interface of claim 1 further comprising a contact lens configured to applanate the anterior surface of the patient's eye.

### Claim 4 (depends on 3)

The interface of claim 3, wherein the contact lens is disposable.
