ABSTRACT:
A shutter mechanism for employment in an ophthalmic laser treatment system mounts between the binoculars and a slit lamp or operating microscope. The shutter mechanism provides a filter movable into the optical viewing path when the laser is under selected power during treatment to prevent damage to the operator's eyes from the laser beam and uncovers the viewing paths when said treatment site is being viewed in conjunction with laser beam alignment and similar pre-operational procedures.
