Abstract
An iridotomy and trabeculoplasty goniolaser lens has a contact lens element, a planar mirror offset from the optical axis of the contact lens element and first and second button lenses mounted on the anterior surface of the contact lens element. Magnification, curvature and location of the button lenses are chosen so as to provide the ability to simultaneously deliver laser energy to the iris of a patient's eye along a first optical path offset from the optical axis of the contact lens element and to view the trabecular meshwork around the region where the laser energy was applied. This ability eliminates the need for a plurality of contact lenses for delivering energy and viewing the eye and further eliminating the need for refocusing the microscope through which the surgeon views the eye.
