Abstract
Various embodiments of optical fiber cables and laser probes are disclosed for providing multi-spot laser beams from a single laser beam source. This permits time-intensive but repetitive laser surgical procedures such as panretinal photocoagulation to be performed with increased accuracy and in a fraction of the time currently allotted for such procedures.
Claims10
A laser probe assembly, comprising:
- a proximal connector adapted for connection to a laser source, the laser source generating a single beam of laser energy;
- a handpiece having a distal end sized for purposes of performing a surgical procedure;
- an optical fiber cable extending from the proximal connector to the handpiece;
- and
- a reflective diffractive element disposed distally of a distal end of the optical fiber cable between the laser source and the distal end of the handpiece and between the laser source and the distal end of the handpiece for splitting the single beam of energy into a plurality of simultaneous laser beams so that the simultaneous laser beams exit adjacent the distal end of the handpiece generally parallel to each other, the simultaneous laser beams, upon exiting from the handpiece, having a size suitable for performing the surgical procedure.
