Abstract
A system for applying therapy to an eye includes an applicator having a conducting element configured to direct energy from an energy source to an application end of the conducting element, where the application end has an eye contact portion. A positioning system receives the applicator and positions the eye contact portion in stable engagement with the surface of an eye. In some embodiments, the conducting element is disposed within a housing for the applicator and an adjustment system is employed to move the conducting element relative to the housing. The adjustment system enables controlled movement of the conducting element and the eye contact portion against the corneal surface. In particular embodiments, sufficient contact between the applicator and the cornea is determined by causing applanation of the cornea. In other embodiments, a physical measurement device, such as a strain gauge, is employed to determine when sufficient contact has been established.
