Anterior chamber tube shunt to an encircling band, and related surgical procedure
First Claim
1. An implant for use in a surgical technique to treat neovascular or refractory glaucomas, said implant comprising:
- a tube sized so that a first end thereof maybe inserted into the anterior chamber of the eye,a band sized so as to extend completely around the equator of the eye, said band having a U-shaped groove formed therein which extends throughout the length of said band, said band sized to surround said tube,a second end of said tube being mounted in said groove, said tube extending in said groove around the equator of the eye over nearly the entire length of said groove, and the first end of said tube having an oblique opening.

Abstract
An implant and a surgical technique involving the anterior chamber tube shunt to an encircling band treatment for reducing neovascular and other refractory glaucomas is disclosed. The implant is a tube connected to a band. One end of the tube is located in the anterior chamber of the eye and the other end of the tube is mounted to the band, which is mounted around the equator of the eye. The length of the tube approximates the length of the band to initially restrict flow of aqueous from the anterior chamber and thereby prevent hypotony. Additionally, all surfaces of the implant may be treated with a heparin complex before implantation of the device.

6. A method for treating neovascular or refractory glaucomas with a surgical implant, said method comprising the steps of:
-
providing a band sized to fit around the equator of an eye, the band including a U-shaped groove extending throughout the length of said band; providing a tube sized to fit in said U-shaped groove around the equator of the eye over approximately the entire length of the U-shaped groove; placing said tube in said U-shaped groove; securing one end of the tube into the anterior chamber of the eye; mounting the band around the equator of the eye; inserting the other end of said tube into the anterior chamber of the eye; restricting the flow of aqueous from the anterior chamber because of the length of the tube; said aqueous flowing through said tube, into said band, and then diffusing from said band into the orbit. - View Dependent Claims (7)
