Imaging Surgical Target Tissue by Nonlinear Scanning
First Claim
1. A method for guiding an eye surgery, comprising the steps of:
- positioning an eye in relation to an imaging system;
creating first scan data by determining a depth of an eye target region at a first set of points along a first arc;
creating second scan data by determining a depth of the eye target region at a second set of points along a second arc;
determining target region parameters based on the first and second scan data; and
adjusting one or more surgical position parameters according to the determined target region parameters.

Abstract
Systems and techniques for laser surgery based on imaging a target tissue by nonlinear scanning are presented. In one implementation, a method for guiding an eye surgery can include the steps of: positioning an eye in relation to an imaging system; creating first scan data by determining a depth of an eye target region at a first set of points along a first arc; creating second scan data by determining a depth of the eye target region at a second set of points along a second arc; determining target region parameters based on the first and second scan data; and adjusting one or more surgical position parameters according to the determined target region parameters.
