1. A system for ophthalmic laser surgery, the system comprising:
- a laser source adapted for ophthalmic laser surgery;
a surgical tip adapted to transmit light from the laser source;
a reference window affixed to the surgical tip at a fixed position relative to the laser source;
a patient interface adapted to couple between an eye and the surgical tip;
an applanation lens coupled to the patient interface; and
an optical sensor adapted to detect interference generated between light reflected off the reference window and light reflected off the applanation lens during a coupling procedure between the surgical tip and the patient interface.

Abstract
A system for ophthalmic laser surgery is disclosed. A laser source is adapted for performing ophthalmic laser surgery. A surgical tip is adapted to transmit light from the laser source toward an eye. A reference window is affixed to the surgical tip at a fixed position relative to the laser source. A patient interface is adapted to couple to the eye and to the surgical tip. An applanation lens is coupled to the patient interface. An optical sensor is adapted to detect interference generated between light reflected off the reference window and light reflected off the applanation lens during a coupling procedure between the surgical tip and the patient interface.
