Abstract
An apparatus for ophthalmic laser treatment of the eye of a patient has a slit image projector which projects a slit image along a common optical axis into the eye of a patient to illuminate the eye, and a laser beam projector which projects a laser beam spot along the common optical axis into the eye of the patient to treat the eye. A common reflector is disposed on the common optical axis for selectively reflecting the slit image and the laser beam spot toward the eye. The reflector has one section positioned to reflect and direct the slit image toward the eye to illuminate the eye, and another section driveably displaceable relative to said one section to reflect and direct the laser beam spot toward the eye to thereby scan the laser beam spot relative to the slit image. Observation equipment is used for observing the slit image and the laser beam spot projected into the eye of the patient to determine the portion of the eye to be treated with reference to the slit image. A manipulator is operated while the laser beam spot is being observed for driving the other section of the reflector to enable the same to scan the laser beam spot within the determined portion of the eye to carry out the ophthalmic laser treatment.
