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 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 of the patient's eye, aligning the internal reflectors with the quadrants of the patient's eye, directing laser pulses through each internal reflector until the trabecular meshwork in each quadrant of the patient's eye has been treated.
