The PRESERFLO™ MicroShunt is suitable for patients with primary open-angle glaucoma where the eye pressure (IOP) remains uncontrolled whilst on maximum tolerated medical therapy and/or where glaucoma progression warrants surgery.
The PRESERFLO™ MicroShunt is a small, tube-like drainage device made of a soft, flexible biomaterial that conforms to the curve of your eye. It is used to control IOP by creating an escape tunnel for any excess fluid from inside the eye to safely drain into a small blister, or filtering bleb, under the top eyelid. This will help to relieve pressure and prevent any further damage to the optic nerve. The implant itself measures 8mm in length, and less than 1mm in thickness and has a winged design. These dimensions ensure the correct rate of fluid flows out of the eye, while the wings help to secure the device and prevent leakage.
