Abstract: An implant for inserting into an exposed Schlemm's canal is proposed. The implant insertable into the lumen of Schlemm's canal includes an elongated tube which includes an axially extending continuous connecting part having several openings or recesses distanced from each other by web shaped ring members and connecting to the interior of the tube with and with arc shaped surfaces, such that in inserted condition the webs are bearing in supporting manner against the inner wall of the lumen of Schlemm's canal. The openings/recesses form a direct and permanently open connection between the trabecular tissue and the small channels of the channel system for natural trabecular drainage of the aqueous humor.
