Abstract
An aiming beam coincident with a laser beam is provided in a modified slit-lamp apparatus. The aiming beam is resolved into a number of images displaced with respect to the axis of the slit lamp imaging rays bracketing the intersection of the laser beam and the axis of slit lamp rays, which intersection is their common focus. As the common focus is moved close to a target tissue within the eye, the target tissue to be treated renders each of the images successively sharply visible while the other images remain blurry or not visible. Thus an efficient rough or long-range system is provided for focusing the laser on the target tissue.
