Note: In 2018, the manufacturer of the CyPass® micro-stent to treat glaucoma decided to voluntarily withdraw it from the market. Learn why the manufacturer took this step, and what you should do if you have already had the CyPass micro-stent procedure.

  • Narrator: Glaucoma: A group of diseases that damage the optic nerve is often caused by increased pressure in the eye, called intra-ocular pressure or IOP. Increased IOP is usually due to blocked drainage in the eye. If left untreated glaucoma can lead to severe vision loss and blindness. Fortunately, there are treatments available to slow the progression of glaucoma, including minimally invasive glaucoma surgery, called MIGS.

    MIGS uses microscopic devices and tiny incisions to reduce IOP and slow the progression of glaucoma. MIGS may allow glaucoma patients to reduce their dependence on eyedrops.

    One type of MIGS is a micro-stent. Micro-Stents help lower internal I pressure by increasing the outflow of fluid. These tiny implants or inserted at the edge of the iris and allow them fluid to access the drainage channel or bypass a blocked channel. Micro-stents or usually inserted during cataract surgery and remain in the eye permanently after the surgery. Your eye maybe slightly red and swollen and pressure may increase temporarily. Your vision may also be blurry for a few weeks after surgery but you can use your eyes normally.

    You may be given eye drops to prevent infection and reduce swelling. If you feel unusual discomfort. Contact your doctor immediately. Talk with us today to learn whether MIGS is an option for you or someone you know with glaucoma.
