SYSTEMS AND METHODS FOR TREATING TARGET TISSUE IN THE VITREOUS CAVITY

摘要

A system and its method for treating targeted tissue in the vitreous cavity of an eye include a laser unit for generating a laser beam and a detector for creating an image of the targeted tissue. The system also includes a computer which defines a focal spot path for emulsifying the targeted tissue. A comparator that is connected with the computer then controls the laser unit to move the focal spot of the laser beam. This focal spot movement is accomplished to treat the targeted tissue, while minimizing deviations of the focal spot from the defined focal spot path.

1. A system for in vivo treatment of target tissue in the vitreous cavity of the eye, the system comprising:
a laser unit for generating a laser beam, and for directing the laser beam along a laser beam path to a focal spot to treat target tissue by Laser Induced Optical Breakdown (LIOB); a detector for creating an image of the target tissue; a computer connected to the laser unit, and to the detector, for guiding the focal spot of the laser beam in accordance with a predetermined computer program, wherein the computer program defines a focal spot path, through the target tissue within the vitreous cavity; and a comparator connected to the detector and to the computer for determining a deviation of the focal spot from the defined focal spot path to produce an error signal indicative of the deviation, and for moving the focal spot to minimize the error signal during treatment of the target tissue.
