Abstract
A system for accurately guiding a laser focal point along a predetermined path within the stroma of a cornea includes a contact lens for conforming the anterior surface of the cornea to a radius of curvature, R , that is approximately 8.3 mm. Conforming the cornea to the lens causes minimal discomfort to the patient and does not upset the three-dimensional architecture of the corneal lamellae. As the focal point is advanced along a path within the cornea, the laser source is selectively translated parallel to the optical axis of the cornea to control the depth of the laser focal point. The movement includes three components: a first component, z that is dependent upon the shape of the contact lens, a second component, z that compensates for refraction at the surfaces of the contact lens, and a third component, z , that compensates for refraction caused by the anatomical configuration of the cornea.
