The tube shunt is a medical device used in the treatment of glaucoma for those patients not responding to medication or surgical intervention. Used to regulate ocular pressure levels, the tube shunt is a device that drains excess fluid from the eye. The fluid flows through the tube and out of the eye into a reservoir where it can be safely absorbed by surrounding tissue. It is implanted on the outer surface of the eye, but covered by conjunctival tissue so it is not visible to others or felt by the patient.
Proven for both consistency and long-term effectiveness, the tube shunt has been demonstrated to be effective in lowering intraocular pressure both short and long term. Once the valve has been implanted, most patients can reduce or stop taking their glaucoma medications, according to their physician's instructions.
The tube shunt is implanted during an outpatient procedure with a local anesthetic. The surgery takes approximately one hour. To promote healing, patients will be given a prescription for eye drops to relieve discomfort and reduce swelling in the eye. Follow-up appointments are essential to measure ocular pressure and determine whether any minor adjustments to the glaucoma valve are necessary.
