Abstract
A laser is used to reopen the natural drainage passageways in the eye or to form new passageways to enable the drainage of the aqueous humor from the eye. In one procedure, an Er:YAG laser is used to ablate occluding tissue in Schlemm's canal. In another procedure, the Er:YAG laser is used to open occluded openings in the ciliary body. In yet another procedure, the Er:YAG laser is used to form a new passageway comprising a plurality of interconnected passageway segments from the exterior of the eye through the sclera to the anterior chamber to enable the drainage of the aqueous humor.
