Abstract
Abstract There is provided an apparatus and methods for computerized laser surgery. The apparatus comprises apparatus for displaying in real time a visually sensible image of the area of surgery, apparatus for displaying in overlay over the visually sensible image a simulation of the effects of operator indicated laser surgical procedures on the area of surgery and automated apparatus for carrying out the operator indicated laser surgical procedures following the display thereof. The method includes the steps of simulating the effects of operator indicated laser surgical procedures on an area of surgery, tuning parameters of a beam of a surgical laser, aiming the apparatus for transmitting laser energy at each point of the surgery, low energy firing of the low energy laser beam at an operator indicated surgery point thereby to ensure that the surgical laser is correctly aimed and high energy firing of the surgical laser at the operator indicated surgery point thereby to treat the point.
