A method, apparatus and system for a transverse tracker is described that can greatly improve the accuracy, speed, range, reliability, versatility, safety, and efficacy of interventions such as laser microsurgery, particularly ophthalmic surgery, and industrial micromachining. The instrument and system disclosed are applicable to those situations wherein the positioning accuracy of laser lesions is critical, and/or whenever precise operations on a target or series of targets subject to random movement during a procedure are to be effected. The present invention provides means for stabilizing the motion of targets in a plane perpendicular to the axial direction, thus allowing an imaging system, diagnostics illumination, and/or laser beam to maintain a lock on the target area, regardless of its movement. The invention also provides means for recording eye movements in real time and in which data can be stored and manipulated for the purpose of compensating for lateral target motion by either hardware or software means. Unique attributes provided in the tracking system include means for (1) sensing contrast in recognizable large scale boundaries such as the change between the cornea/sclera interface (limbus), thereby to determine the absolute location and orientation of these boundaries, all without having to resort to digital sampling techniques and (2) dual mode operation of an electronic control system compatible with all analog technologies, thereby substantially increasing the speed of operations over other, comparable digital method.

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.

Apparatus and methods for dynamically controlling electric field distribution within tissue disposed at various depths beneath the skin at a target region of a patient's body by independently controlling the electric potential of each of a plurality of electrodes in relation to the electric potential of a ground pad. By controlling electric field distribution during a procedure, a target tissue at particular depths beneath the skin can be selectively heated relative to adjacent non-target tissue. At least one of the electrodes and the ground pad may comprise a spiral inductor comprising a substantially planar spiral of electrically conductive material.

A method, apparatus and system for template-controlled, precision laser interventions is described that greatly improves the accuracy, speed, range, reliability, versatility, safety, and efficacy of 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, wherever accurate containment of the spatial extent of a laser lesion is desirable, and/or whenever precise operations on a target or series of targets subject to movement during the procedure are to be effected. A key object of the present invention is to implement a fully integrated approach based on a number of different instrumental functions all operating in concert within a single, fully automated unit. Each of the complementary, and at times competing, functions requires its own technologies and corresponding subassemblies. 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) and provide the means for converting the template pattern into a sequence of automatic motion instructions to direct a laser beam to focus sequentially on a number of points in three dimensional space which will, in turn, replicate the designated template pattern into the corresponding surgical or industrial site. The user interface also continuously presents three dimensional visual information to the surgeon/user during the operation, as to the surrounding features of the subject tissue, the topography of the surface to be operated upon or below said surface at a prescribed depth, and as to the precise aiming location and depth of penetration of the treatment laser beam. The system thus comprises the following key elements: (1) a user interface, consisting of a video display, microprocessor and controls,(2) an imaging system, which may include a surgical video microscope with zoom capability, (3) an automated 3D target acquisition and tracking system that can follow the movements of the subject tissue, for example an eye, during the operation, thus allowing the surgeon/user to predetermine his firing pattern based on an image which is automatically stabilized over time. Tracking is considered a critical element of the system designed not only to diagnose, but to also select treatment, position the treatment beam and image the tissue simultaneously with the treatment, while assuring safety at all times, (4) a laser, with which can be focused so that only the precise lesions described by the user interface are effected. The laser parameters are selected to allow execution of the desired procedure at a high rate of independently targeted shots per second, as well as tuning to selectively generate photodisruption of tissues, or photocoagulation as desired, (5) a diagnostic system, incorporating a mapping and topography means for measuring precise surface shapes prior to and subsequent to a procedure, said measurements to be executed on-line within time scales not limited to human response times, and (6) a fast reliable safety means, whereby the laser firing is interrupted automatically, should any conditions arise to warrant such interruption of the procedure.
