Abstract
An instrument for measurement of the diameter of the anterior chamber of the eye includes an elongate member for insertion into the anterior chamber through an incision in the cornea having a flared distal end for positioning against the juncture of the iris and the cornea opposite the incision, a slide movable along the elongate member having an arm depending therefrom and extending away from the distal end of the elongate member to terminate in a flared end for positioning against the juncture of the iris and the cornea adjacent the incision, and indicia means including a scale and a pointer carried on the elongate member and the slide such that movement of the slide to position the flared end of the arm against the juncture of the iris and the cornea adjacent the incision causes relative movement of the scale and the pointer to provide an indication of the diameter of the anterior chamber.
