Eye therapy system
First Claim
1. A system for applying therapy to an eye, the system comprising:
- at least one energy conducting element configured to apply an initial amount of energy according to an initial pattern to an eye, the initial amount of energy according to the initial pattern causing a reshaping of an aspect of the eye, the at least one energy conducting element including an inner conductor and an outer conductor separated by a gap, a distal end of the outer conductor and the inner conductor defining the initial pattern;
a measurement device operable to measure an amount of reshaping in response to an application of the initial amount of energy according to the initial pattern and provide a feedback indication of the measured amount of reshaping; and
a controller operably coupled to the at least one energy conducting element and the measurement device, the controller being configured to;
receive the feedback indication of the amount of reshaping from the measurement device and, in response, to the feedback indication of the amount of reshaping,determine a second amount of energy and a different pattern based on the feedback indication of the reshaping received from the measurement device, the at least one energy conducting element being configured to apply the second amount of energy according to the different pattern to the eye, andcause the at least one energy conducting element to apply the second amount of energy according to the different pattern to the eye, the second amount of energy according to the different pattern causing a different reshaping of the aspect of the eye.

Abstract
The cornea is reshaped in multiple steps according to varying amounts of energy in varying patterns and/or at varying locations to achieve a customized reshaping of the cornea to address the specific needs of an individual patient. The varying amounts of energy may be applied via one or more conducting elements, which include an outer conductor and an inner conductor disposed within the outer conductor, a distal end of the outer conductor and the inner conductor defining the varying patterns. For example, one step may form a substantially circular lesion to flatten a first portion of the cornea to treat presbyopia, while another step may form a substantially circular and concentric lesion having a greater diameter to steepen a second portion of the cornea to treat hyperopia. Advantageously, continuous transitional regions are formed relative to the reshaped portions to provide vision for intermediate distances.
