A laser treatment apparatus providing a slit-lamp microscope with which an eye of a patient is observed, a box unit which is provided with an optical system to deliver a laser beam inside an observing visual field of the slit-lamp microscope, an attachable device which mounts the box unit on the slit-lamp microscope, and an optical fiber through which a laser beam for ophthalmic treatment is delivered to the box unit, wherein the box unit is provided with a dichroic mirror having characteristics of reflecting the laser beam for treatment to the patient's eye while absorbing a therapeutic surgery laser beam being incident to the dichroic mirror.

Laser treatment apparatus

This application discloses a laser apparatus including a binocular indirect ophthalmoscope for irradiating a treatment laser beam on an eye to be treated comprising, an optical fiber for guiding the treatment laser beam to the binocular indirect ophthalmoscope, an optical element, which reflects the treatment laser beam while penetrates a pair of observation beams of the binocular indirect ophthalmoscope is provided in the object side of an ophthalmoscope lens, an optical system which directs the treatment laser beam to said optical element so that the axis of the treatment laser beam coincides with the substantial center of said pair of observation beam axes, whereby the power of the treatment laser beam becomes stable owing to above constitution.
