Abstract

A laser and a laser probe are used in conjunction with a suture to remove a blockage in Schlemm's canal. The suture is advanced into Schlemm's canal until the suture comes into contact with tissue blocking the canal. The laser probe follows the path of suture until the laser probe is proximal to tissue blocking the canal. The laser is activated to apply pulsed laser energy to the tissue blocking the canal, thereby ablating the occluding tissue to reopen Schlemm's canal.
