Abstract:
Laser ablation devices that utilize beam profiling assemblies to clean and process surfaces are described herein. A method includes directing a laser beam in a geometrical pattern at an arcuate surface of a cylindrical target, blocking a portion of the laser beam to prevent a portion of the geometrical pattern from contacting the cylindrical target, and rotating the cylindrical target as the laser beam contacts the arcuate surface so as to ablate the cylindrical target.
Abstract:
An ophthalmic treatment system and method for performing therapy on target tissue in a patient's eye. A delivery system delivers treatment light to the patient's eye and a camera captures a live image of the patient's eye. Control electronics control the delivery system, register a pre-treatment image of the patient's eye to the camera's live image (where the pre-treatment image includes a treatment template that identifies target tissue within the patient's eye), and verify whether or not the delivery system is aligned to the target tissue defined by the treatment template. The control electronics control the delivery system to project the treatment light onto the patient's eye in response to both an activation of a trigger device and the verification that the delivery system is aligned to the target tissue, as well as adjust delivery system alignment to track eye movement.
