iPad, iPhone, iStent – More on the Glaucoma Technology at Boston Vision
Some numbers estimate that about 3 million Americans have glaucoma. Fortunately, new glaucoma technologies are developing faster than ever that don’t require daily management like traditional treatments for glaucoma. If you’re looking for long-term, effective solutions for glaucoma, then our team at Boston Vision can help you explore our most advanced and long-lasting options. Here’s what to know about iStent, our comprehensive solution for glaucoma.
What Causes Glaucoma?
Glaucoma is caused by long-term damage to the optic nerve. When fluid builds up in the eye, it increases intraocular pressure (IOP), eventually damaging the nerve bundle in the back of the eye that connects to the brain. Although there are various risk factors for glaucoma, this is its underlying cause. Over time, glaucoma can lead to permanent vision loss.
There are multiple types of glaucoma but the most common is called open-angle glaucoma. This occurs when the eye’s drainage canals become damaged and can no longer drain away excess fluid. Open-angle glaucoma is the type of glaucoma most easily treated by iStent.
How Does iStent Work?
iStent is a tiny medical implant that can be inserted into the cornea. This tube-like device bypasses the natural blocked drainage canals of the eye and allows for fluid to drain as normal. Over time, iStent can allow your eyes to better regulate intraocular pressure, reducing damage to the optic nerve. It’s one of the most advanced and exciting new ways to treat glaucoma with excellent results.
How Do Cataracts Play a Role?
Both cataracts and glaucoma occur together commonly in people over 60. Although they are not related, it’s common for patients with cataracts to develop glaucoma and vice versa. Fortunately, cataract surgery presents a unique opportunity for iStent. Cataract surgery involves replacing the natural lens with an implantable device (intraocular lens implant). Although iStent can be placed during its own procedure, your ophthalmologist may recommend placing iStent at the same time as your cataract surgery. This process reduces the need for multiple procedures and often yields the best results when it comes to preserving your vision and preventing later vision loss as a result of glaucoma.
