What Is The CyPass® Micro-Stent?
The CyPass® Micro-Stent is a device for treatment of mild to moderate primary open-angle glaucoma that is intended to be implanted along with cataract surgery. It is a very small tube that is implanted just below the surface of the eye, lowering eye pressure and reducing or eliminating the need for glaucoma medications. The micro-stent is implanted into the supraciliary space to facilitate suprachoroidal aqueous outflow and is considered minimally invasive.
How Does It Work?
Glaucoma is commonly associated with a build-up of fluid pressure inside the eye. Eye pressure increases because the eye’s fluid drainage channels become blocked. The CyPass® Micro-Stent is placed inside your eye just where the colored part (iris) meets the white part of the eye (sclera). It bypasses the major drainage channel that is blocked and enhances one of the other natural drainage pathways. This allows excess fluid to drain from the eye, reducing eye pressure. The fluid drained inside the eye is different from tears.
Who Is A Good Candidate for the CyPass®Micro-Stent?
The CyPass® Micro-Stent is designed to be implanted at the time of cataract surgery to lower eye pressure in patients with open-angle glaucoma. The device can also be used when eye pressures are not adequately controlled with eye drops or laser, as an alternative to more invasive operations. The CyPass® Micro-Stent can be used in patients with mild to advanced glaucoma.
Benefits Of The CyPass® Micro-Stent
The CyPass® Micro-Stent is designed to lower eye pressure and reduce the risk of vision loss from glaucoma. The procedure to insert the CyPass® Micro-Stent is faster, more straightforward, and less invasive than traditional operations for glaucoma. In a clinical trial, eye pressure was reduced by 34% at 1 year in patients who had the CyPass® Micro-Stent and medication use was reduced by 50%. The CyPass® Micro-Stent will not cure your glaucoma, reverse any damage already caused by glaucoma, or bring back any lost vision.
What Is The Recovery Like?
Following surgery, your eye may be slightly bloodshot and swollen for a few days. Your vision may also be blurry for 1 – 2 weeks after the procedure. You may read and watch television; these activities will not harm your eye. You will be given new anti-inflammatory and antibiotic eye drops to prevent inflammation and infection.
The CyPass® Micro-Stent does not start to work straight away so you should continue your glaucoma drops in the operated eye. Any drops you use in your other eye must also be continued as normal. As with all eye surgery, you should avoid strenuous activity for the first month including swimming, tennis, jogging, and contact sports. Most people take 1 – 2 weeks off work after surgery, however, the length of time will depend on the nature of your work. You should avoid wearing eye makeup for approximately 4 weeks after surgery.
You will be asked to wear a shield over your eye at night for the first week or so, to prevent accidental injury to your eye whilst you are asleep. It is safe to fly after surgery, however, you will need to be seen regularly by your surgeon in the early post-operative period.
