Disclosed herein are collagen films which rapidly dissolve at 35&deg; C. Also disclosed are methods for the preparation of the collagen films and their use as a vehicle for delivering a dose of therapeutic compound to a specific tissue site.

Compound delivery using rapidly dissolving collagen film

A laser and a laser probe are used in conjunction with a suture to remove a blockage in Schlemm's canal. The suture is advanced into Schlemm's canal until the suture comes into contact with tissue blocking the canal. The laser probe follows the path of suture until the laser probe is proximal to tissue blocking the canal. The laser is activated to apply pulsed laser energy to the tissue blocking the canal, thereby ablating the occluding tissue to reopen Schlemm's canal.

Laser surgical procedures for treatment of glaucoma

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.
