Abstract
A method, apparatus and system for template-controlled, precision laser interventions is described that greatly improves interventions such as laser microsurgery, particularly ophthalmic surgery, and industrial micromachining. The instrument and system are applicable to those specialties wherein the positioning accuracy of laser lesions is critical, such as whenever precise operations on a target or series of targets subject to movement during the procedure are to be effected. The system includes a user interface, wherein the user can either draw, adjust, or designate particular template patterns overlaid on a live video images of the target (such as the cornea) which are stabilized and produce an apparently stationary display of the target and provide the means for converting the template pattern into a sequence of automatic motion instructions to direct a laser beam to be sequentially applied replicating the designated template pattern into the corresponding surgical or industrial site.
