Abstract: A self-contained, freely movable laser system includes a laser, an energy storage unit such as a battery, and a sealed heat exchanger for removing excess heat from the laser. The laser system needs only a standard low voltage AC power source for operation.

Abstract: An ophthalmic slit lamp is modified by adding a laser to it to be used for microsurgery. The laser is mounted on the lamp so its beam is projected into the eye along one axis while the normal viewing image generated by the lamp is focused into the eye from another angle. An aiming image is focused into the eye coincidentally with the laser beam so that the distance between the two images and their relative position may be determined by their apparent positions as seen from the viewing binoculars of the lamp.

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.
