Patent ID: 8882757

Claim:
A system for treating an eye disorder, comprising: an energy source; a thermokeratoplasty applicator configured to apply thermokeratoplasty therapy to an eye, the applicator having a distal end, the applicator being configured to receive an amount of energy from the energy source, a first portion of the energy received by the applicator configured to be transmitted through the distal end to the eye and a second portion of the energy received by the applicator being reflected from the distal end of the applicator; a dual directional coupler configured to detect the reflected energy, the reflected energy being indicative of an amount of contact between the distal end and the eye, the dual directional coupler being further configured to provide a signal indicative of the detected reflected energy; and an adjustment system configured to advance the distal end of the applicator toward the eye until a predetermined amount of contact is determined based on the signal indicative of the reflected energy, wherein the signal corresponding to the reflected energy has a power that decreases as the amount of contact increases.
