Abstract
A method and an appliance for carrying out the method, by means of which the necessary outflow of the aqueous humour which is continuously being renewed in the eye is ensured, and thus the natural intraocular pressure is maintained, are proposed. For the treatment, the sclera (13) undergoes operative lamellar incision for partial exposure of the canal of Schlemm (15), and the portion (13') which is opened out is held by means which are not depicted. A medium is introduced into the canal of Schlemm (15) by means of a tube (20) which is introduced into the circular canal of Schlemm (15), by which means the upstream trabecular tissue (15') is hydraulically expanded and traumatically opened at several points (15") and, at the same time, the points (15") are wetted by the highly viscous medium.
