  • Publication number: 20220221250
    Abstract: The present invention discloses a canting indicating rifle scope. An eyepiece assembly is located on one end of a body tube, and an objective bell extends from the opposite end. Lenses are positioned within the scope and permit visual acuity and magnification adjustments. A reticle is located between a focus lens and an ocular lens. A level is located between the reticle and the ocular lens. A canting turret extends from a parallax turret on the body tube and contains a circuit board, a battery power source, and an accelerometer. The circuit board is electrically connected to the electronic accelerometer and to a level LED positioned to illuminate the level. The circuit board is electrically connected to a reticle LED to illuminate the reticle. An activation switch on the exterior of the turret controls the mode of illumination of the reticle and level.

  • Publication number: 20220023099
    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.
