Optical ophthalmic treatment apparatus

An optical ophthalmic treatment apparatus comprising:

• a slit beam projection optical system for projecting a narrow illuminating light beam, having a reflecting member for reflecting the narrow illuminating light beam toward a patient's eye to illuminate the patient's eye said reflecting member having at least a side of an operator and a side of the patient's eye;
• a stereomicroscopic observation optical system for observing the patient's eye;
• a first therapeutic light projecting optical system for projecting a first therapeutic light beam so that the first therapeutic light beam is introduced into the stereomicroscopic observation optical system though a position on the side of an operator with respect to the reflecting member;
• a light path deflecting optical element capable of being inserted in and retracted from a plane including light paths of the stereomicroscopic observation optical system through a position on the side of the patient's eye with respect to the reflecting member, capable of transmitting at least part of the light beam projected by the slit beam projection optical system and capable of reflecting a second therapeutic light beam;
• and
• a second therapeutic light projecting optical system for projecting the second therapeutic light beam so that the second therapeutic light beam is reflected by the light path deflecting optical element inserted in the light path of the stereomicroscopic observation optical system toward the patient's eye.
