Ex-PRESS implant diverts the fluid though an extremely small tube to the outside of the eye without cutting the sclera or it is. It acts just like a heart stent keeping a pathway open so blood (or fluid) can successfully go around the blockage.
The Ex-PRESS mini glaucoma shunt provides a simplified method of filtration surgery for patients with glaucoma. The Ex-PRESS can be implanted following cataract surgery.
