ABSTRACT:
A fiber optic handpiece has portions formed with special contours that facilitate consistent placement of the probe in an axial rather than radial orientation, thus decreasing the likelihood of incidental laser exposure to unintended structures while maintaining the intrinsically higher laser-tissue coupling efficiency of a contact technique. One particular embodiment incorporates features that permit rapid and consistent positioning relative to visible landmark structures such as the limbus, thereby reducing treatment variability.
