Abstract

Apparatus and method for laser surgery in which laser energy, pulsed or continuous, is focussed to a focus spot (FS) of a few microns which is located within tissue, or the like to cause highly localized heating. The pulsed radiation is in the TEM(oo) mode, has a wavelength of approximately 1064 nanometers, the pulses being not in excess of 100 nanoseconds and the pulse rate being approximately 2000 per second. Where the laser beam is continuous or pulsed, it has a wavelength of approximately 1400 to 1800 nanometers, or in photoablative modes, having a wavelength of 190 to about 300 nanometers. The focus spot (FS) may be caused to move relative to the axis of a handpiece (40) which delivers the laser energy to the body. Handpieces (20, 40) are provided in which laser energy is focussed to a focus spot (FS) of ten to thirty microns, and liquid is caused to flow across the exposure site to remove debris, a handpiece having a tubular terminal portion into which liquid is introduced, the distal end (54) of the handpiece having transverse channels (56) for the escape of liquid. A handpiece of the foregoing construction may have an endoscope including a glass contact tip (65) at its distal end and to receive light and to acquire an image of the exposure site. Probes for eye surgery include a quartz rod (82) in a sheath (84), the quartz rod (82) having a beveled distal end surface (83) through which the laser radiation is emitted. Probe has infusion (86) and aspiration (88) passages, the ends of which are coplanar with the beveled end surface (83) of the quartz rod (82).
