Abstract

A lens device for use in Selective Laser Trabeculoplasty (SLT) procedures is provided. The lens device includes four internal reflectors, each having a reflector surface configured to direct a laser beam pulse toward the trabecular meshwork region of a patient's eye. Each of the four internal reflectors is arranged to correspond to a particular quadrant of the patient's eye to enable the entire 360-degrees of the trabecular meshwork to be treated with laser pulses without rotation of the lens device. A method for performing an SLT procedure using the lens device is also provided. The method includes placing the lens device on the patient's eye, aligning the internal reflectors with the quadrants of the patient's eye, and directing laser pulses through each internal reflector until the trabecular meshwork in each quadrant of the patient's eye has been treated.

Dependent claims

A lens device for use in performing a Selective Laser Trabeculoplasty (SLT) procedure to a patient's eye, the device comprising:

a device body having a first end configured to receive a laser beam pulse transmission, a second end configured for placement on a patient's eye, and an interior positioned therebetween;
and
four internal reflectors located within the interior of the lens device;
wherein each of the internal reflectors corresponds to a quadrant of a patient's eye.

A method for performing a Selective Laser Trabeculoplasty (SLT) procedure using a single-mirror lens device to direct laser beam pulses from a laser emitter to the trabecular meshwork of a patient's eye, said method comprising the steps of:

placing the single-mirror lens device onto the patient's eye;
orientate the single-mirror lens device to view a center-line of a lower quadrant of the patient's eye;
transmitting laser beam pulses through the single-mirror lens device to the trabecular meshwork of the patient's eye beginning at the center-line of the lower quadrant and moving around the trabecular meshwork in a clockwise direction to a first edge of the lower quadrant;
ceasing transmission of laser beam pulses and returning to the center-line of the lower quadrant;
and
transmitting laser beam pulses through the single-mirror lens device to the trabecular meshwork of the patient's eye beginning at the center-line of the lower quadrant and moving around the trabecular meshwork in a counterclockwise direction to a second edge of the lower quadrant.
