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.
