Eye drops are the first intervention for many people with glaucoma, Christopher Starr<\/a>, MD, ophthalmologist at Weill Cornell Medicine and NewYork-Presbyterian, tells Health<\/em>. There are different types of eye drops that can lower pressure, either by reducing the production of aqueous humor—the fluid that keeps the eye plump and brings nutrients to the lens and cornea—or by increasing the fluid's drainage, Dr. Starr explains.<\/p>\n While no one is particularly psyched about the prospect of eye surgery, the good news is that there are actually a lot of glaucoma surgeries out there—with different levels of invasiveness—that can effectively reduce your eye pressure to healthy levels. Here's everything you need to know about the different types of glaucoma surgery, and the risks and benefits of each.<\/p>\n Most eye doctors will try eye drops—usually a combination of different eye drops—to lower eye pressure before turning to surgery. If you give non-surgical options a solid try and they still aren't lowering your eye pressure, surgery is the next step.<\/p>\n The other thing to consider here: Some people really just don't like taking eye drops, Sriranjani Padmanabhan<\/a>, MD, ophthalmologist and glaucoma specialist at UCSF Health, tells Health<\/em>. "They can be really frustrating for patients. Eye drops are different than taking a pill; they're much more burdensome; they're harder to use and more uncomfortable," she says. Side effects of eye drops may also be too uncomfortable for some people. People who have a hard time complying with daily eye drops—and therefore, can't get their eye pressure under control—are also good candidates for surgery.<\/p>\n Finally, if you are diagnosed with advanced glaucoma or have acute angle-closure glaucoma, in which a blockage causes a rapid and dramatic increase in eye pressure, surgery is needed to intervene quickly to preserve vision as best as possible. "In advanced stages, earlier surgery is definitely better," Daniel Laroche<\/a>, MD, director of glaucoma services and president of Advanced Eyecare<\/a> of New York and assistant professor of ophthalmology at the Mount Sinai School of Medicine, tells Health<\/em>.<\/p>\n RELATED: What Causes Glaucoma? Here's How This Eye Disease Impacts Your Vision<\/a><\/strong><\/p>\n Within the last decade, a new class of minimally invasive glaucoma surgeries, known as MIGS, have become more popular. Usually used to treat mild to moderate glaucoma, these procedures are often short—about 10-15 minutes, Dr. Padmanabhan says. They use microscopic stents and very tiny incisions to reduce eye pressure, and have minimal complications compared to traditional glaucoma surgeries. <\/p>\n They're often done at the same time as cataract surgery, Dr. Starr says. "We often recommended doing MIGS as an add-on, and the best-case scenario is that patients with chronic glaucoma can be taken off those drops," he says.<\/p>\n According to the Glaucoma Research Foundation<\/a>, the different categories of MIGS procedures include:<\/p>\n There are a handful of minimally invasive laser surgeries that can be done to make the eye drain more efficiently, Dr. Starr says. These are often done in the eye surgeon's office and have minimal recovery time involved. They aren't permanent, though—typically, lasers need to be redone or eventually, eye drops, or more invasive surgeries may become necessary to keep pressure under control. Sometimes, you may need to keep using eye drops even if you undergo laser treatment.<\/p>\n The most common laser surgeries for glaucoma include:<\/p>\n Trabeculectomy is known as the gold standard of glaucoma surgery or those with advanced open-angle glaucoma, Dr. Laroche says. It's a more invasive surgery than MIGS or laser procedures and has a higher complication rate, but it typically does a very good job of lowering eye pressure, he says. During a trabeculectomy, the surgeon will make a small incision in the white part of your eye (the sclera) and remove a portion of the meshwork so that the eye can drain better. It's typically an outpatient surgery—meaning, you can leave the hospital the same day—and the procedure takes about an hour to complete.<\/p>\n Implant surgery is a type of glaucoma surgery that involves inserting drainage tubes into the eye. It's typically used to enhance a trabeculectomy, keeping the surgically added drain open and fluid flowing through it as intended. According to the Glaucoma Research Foundation, implant surgeries are usually done to treat "complicated glaucomas" and glaucoma that happens as a result of an eye injury. They're also used to treat congenital glaucoma (in babies born with glaucoma) and neovascular glaucoma, which happens when certain medical conditions cause blood vessels to overgrow in the eye and block the drainage area. This is also an in-hospital outpatient surgery.<\/p>\n RELATED: Glaucoma Symptoms You Need to Know, According to Experts<\/a><\/strong><\/p>\n Just like all surgeries, glaucoma surgery comes with risks—and some procedures are riskier than others.<\/p>\n MIGS procedures were created specifically to be less invasive and risky than other glaucoma surgery options (which is also why they aren't always as effective and usually work best for people in the early stages of glaucoma). The most common side effects with MIGS procedures are bleeding in the eye and a short-term increase in eye pressure post-procedure.<\/p>\n Common side effects of laser surgeries include swelling and soreness. They can also cause dry eye<\/a> or a scratched cornea—both of which can be painful, but usually will heal quickly. Irritation and blurry vision<\/a> are also common right after a laser treatment, but side effects usually subside by the next day.<\/p>\n Invasive surgeries like trabeculectomy and implant surgery come with more risks and recovery is much longer. These procedures come with a risk of infection, and increase your chance of developing cataracts over time, Dr. Laroche says. They can also cause problems with the cornea, too-low eye pressure, and vision loss, according to the National Eye Institute<\/a>. "That's why you really want to make sure to do this with a really skilled surgeon," Dr. Laroche adds. Recovery can take a while, too. "It's usually about a month before patients feel like themselves again," Dr. Padmanabhan says. "You'll be on post-op medication for a month, your vision will probably be blurry for a while." Depending on the surgery, you may need to go back in to have sutures removed.<\/p>\n You can reduce your risks and make the experience go more smoothly by working with a qualified and experienced eye surgeon who specializes in glaucoma surgeries. And despite the potential side effects, glaucoma surgeries can be very effective in lowering eye pressure and preserving the optic nerve. They may ultimately be necessary to get your eye pressure in check and keep you from losing any vision to glaucoma.<\/p>\n![\"The](\"https:\/\/imagesvc.meredithcorp.io\/v3\/mm\/image?url=https%3A%2F%2Fstatic.onecms.io%2Fwp-content%2Fuploads%2Fsites%2F12%2F2021%2F08%2F24%2Feye-surgery-GettyImages-1272404871.jpg\")
