A shunt valve (10) for treatment of glaucoma in the form of a hollow tubular body (11) insertable into a hole formed in the sclera and provided with retaining shoulders that hold the tubular body in place against fore and aft movement. The valve is carried on and transported by a tool (20) at the front end of which projects a cutting member (23). The cutting member (23) is driven from an energy source under the control of an operator to form a hole in the sclera after which the valve (10) is displaced axially from the tool (20) along a straight line into the hole coaxially thereof. A porous inflatable balloon (52) can be carried by the valve (10) or installed therein subsequent to the implantation of the valve in the sclera to control drainage through the valve. Medicaments and the like can be supplied with the inflatable balloon (52). The cutting member (23) can be a rototrephine or a laser cutter. |
