Methods: Nonrandomized prospective clinical study. Whilst this may not seem much, it has to be remembered that every mmHg reduction in intraocular pressure in glaucoma patients results in a 19% reduction in risk of progression(1). In patients presenting with both cataracts and uncontrolled glaucoma, any of these devices can be placed at the time of cataract surgery. In some patients, the stent reduces the number of pressure-lowering eye drops used. Dr. Yao Liu and Dr. Julia Agapov of the UW Health ophthalmology and visual sciences department, are the first ophthalmologists in Madison to use the iStent® Trabecular Micro-Bypass Stent, which is put into the eye during cataract surgery. There, the fluid is absorbed by blood vessels nearby. The iStent is one of the new generation medical devices which has recently become available in Australia for use during cataract surgery in patients with glaucoma. The stent facilitates intraocular pressure lowering thereby potentially either minimising glaucoma medication, or giving better intraocular pressure control in patients who are poorly controlled. The US Food and Drug Administration has approved the first stent for use in cataract surgery to reduce intraocular eye pressure in adult patients with glaucoma. There is definitely a learning curve associated with its use and is probably best reserved for ophthalmic surgeons who are familiar with the anatomy of the trabecular meshwork. Forty-one eyes of 33 patients with open-angle glaucoma underwent a XEN 45 Gel Stent implantation combined with MICS. With this type of glaucoma, the. The U.S. Food and Drug Administration approved iStent for glaucoma in 2012. Cataracts may naturally coexist with glaucoma, have a causative effect on glaucoma, and/or may even be a result of glaucoma surgery. ... iStent inject® includes two heparin-coated titanium stents with each stent measuring approximately 0.23 mm x 0.36 mm [Figure 1]. Alcon's CyPass Micro-Stent is a small tube with tiny holes that is surgically placed (implanted) in the eye. The iStent is one of the new generation medical devices which has recently become available in Australia for use during cataract surgery in patients with glaucoma. The iStent medical implant was approved by the FDA in 2012 and plays an important role in successful glaucoma and cataract surgery. Glaucoma is pressure inside your eye , like a basketball being overinflated. The stent is then released once in place by depressing a button on the introducer. There are also newer procedures called MIGS, or minimally invasive glaucoma surgery. These surgeries help lower eye pressure but may not lower it enough to stop all glaucoma medications. iStent eye surgery: what is the iStent? (1) Chauhan A. Acta Ophthalmol 2008;126:1030-1036. Approximately, 6-8 weeks post-operatively, a fibrous capsule forms around the plate and regulates flow. Get ophthalmologist-reviewed tips and information about eye health and preserving your vision. The iStent, when implanted at the time of cataract surgery gives further lowering of intraocular pressure of around 16%. The i Stent inject Procedure: A Complement to Cataract Surgery. A gonio lens is required to visualise the trabecular meshwork. The ability to visualise the trabecular meshwork during surgery is crucial and inability to do so would be the main reason not to implant it. MIGS procedures (including the iStent inject), are generally reserved for patients with stable, mild-to-moderate glaucoma and who do not require complex surgery. These procedures are called MIGS, or microinvasive glaucoma surgeries. Glaucoma surgeries include the delicate, microscopic incisional trabeculectomy (with or without ExPRESS microshunt implantation), tube shunt implantation (a shunt is a glaucoma drainage device), and cyclophotocoagulation. The implantation of the iStent is usually performed at the end of the cataract procedure. To evaluate learning effects with respect to outcomes of a microinvasive glaucoma stent (MIGS) inserted during cataract surgery in glaucoma patients. iStent drainage implant surgery is approved to treat moderate to advanced open-angle glaucoma in people who are already using medication to reduce high pressure in the eye. The iStent® Trabecular Micro-Bypass Stent (Models GTS100R and GTS100L) is indicated for use in conjunction with cataract surgery for the reduction of intraocular pressure (IOP) in adult patients with mild to moderate open-angle glaucoma currently treated with ocular hypotensive medication. Then a bubble-like pocket, called a bleb, is also created over the white of the eye. In the US alone, it is estimated as many as 20% of patients undergoing cataract surgery also have glaucoma. The iStent works by bypassing the trabecular meshwork which is the site of outflow resistance in patients with glaucoma. Other patients have cataracts and a kind of glaucoma called narrow- or closed-angle glaucoma. These procedures use the same incision, or small cut, to enter the eye that your surgeon uses to remove the cataract. The excess fluid drains out of the eye through the flap and into the bleb.

Cataract surgery and glaucoma shunt procedures During this surgery, your ophthalmologist will remove your eye’s cloudy lens and replace it with an artificial one . Phacoemulsification with intraocular lens placement can be completed first. Cataract surgery is one of the most opportunistic times we have to help a glaucoma patient. It is a surgical titanium micro-bypass stent that’s preloaded into a sterile inserter, which helps eye surgeon implant the iStent … Many of these surgeries can be combined with cataract surgery for people with mild to moderate open-angle glaucoma. It can be implanted on its own, or combined at the same time as cataract surgery for patients who have both cataract and glaucoma. Intraocular pressure lowering in cataract surgery. This stent can be used in combination with cataract surgery to decrease intraocular pressure in people who have both a cataract and mild to moderate open-angle glaucoma. However, that’s not the case when a patient has pseudoexfoliation; in that situation there’s a good chance you’ll encounter problems. “The iStent trabecular meshwork bypass stent [from Glaukos] was introduced to the market in 2012 and, as with any surgical procedure, surgical device or … A cataract is a clouding of the lens inside the eye which leads to a decrease in vision. The iStent Inject is implanted to decrease eye pressure. In 2012 the FDA approved a device called the iStent Trabecular Micro-Bypass Stent System to treat symptoms of glaucoma. Patients were followed for 24 months postoperatively. At this stage, the iStent inject can only be implanted in glaucoma patients who are also undergoing cataract surgery (i.e. To help lower your eye pressure, he or she will also put a tiny, plastic tube called a shunt under the thin, clear membrane covering the white of your eye. With the newest advancements in optical technology, our eye surgeons can help slow the progression of glaucoma for cataract surgery patients. The decision to implant the iStent is usually made in the pre-operative period in patients who have glaucoma. Yes, it's possible to have cataract surgery if you have glaucoma. This helps lower eye pressure. This is the first stent device approved for use in combination with cataract surgery to reduce intraocular [i.e., within the eye] pressure in adult patients with mild or moderate open-angle glaucoma and a cataract who are currently being treated with medication to reduce intraocular pressure. Examples of devices used in this procedure are the Xen Gel Stent and PRESERFLO MicroShunt. ... or cornea during surgery… For those with more severe glaucoma, having a trabeculectomy with cataract surgery may lead to lower eye pressure. METHODS: Eyes with mild to moderate glaucoma with an unmedicated intraocular pressure (IOP) of 22 mm Hg or higher and 36 mm Hg or lower were randomly assigned to have cataract surgery with iStent trabecular micro-bypass stent implantation (stent group) or cataract surgery alone (control group). A laser glaucoma surgery called selective laser trabeculoplasty (SLT) is now considered a first-line surgical treatment for open-angle glaucoma and may reduce the number of eye drops a person needs to use every day to treat glaucoma. Stenting to help treat glaucoma is used in combination with cataract surgery to reduce pressure inside the eye in certain adult patients who have mild or moderate open-angle glaucoma. As an alternative to a trabeculectomy, a cataract operation is a potentially good way to gain further lowering of pressure in people who perhaps are on maximal medical therapy and who have perphaps  have also had  laser treatment (SLT) but still do not have ideal pressure control. In other cases, glaucoma is well-controlled without surgery but cataracts are limiting vision. To help lower your eye pressure, he or she will also put a tiny, plastic tube called a shunt under the thin, clear membrane covering the white of … For patients with more serious glaucoma and the need for cataract surgery, a combination cataract removal and glaucoma filtering procedure can be considered. It increases surgical time only minimally. The following illustration shows the path of aqueous within the eye and out through the iStent. During the trabeculectomy, your surgeon creates a tiny opening, or flap, in the white of your eye. During this surgery, your ophthalmologist will remove your eye’s cloudy lens and replace it with an artificial one. The iStent is the first ab interno (from the inside) micro-bypass implant for the treatment of glaucoma.The iStent is made of titanium and is a tube-like device only 1 mm in length with a … There are some newer glaucoma procedures that do not require as much cutting into the eye. Cataract surgery usually goes well, but it helps to know what to look out for. The shunt sends blocked fluid inside the eye to a small, plastic plate your surgeon puts on the eye wall. iStent Glaucoma Surgery iStent is a Safe & Effective Treatment for Glaucoma. The iStent ® Trabecular Micro-Bypass Stent is the smallest medical device ever approved by the U.S. Food and Drug Administration. Relief for People with Glaucoma . Purpose: To verify the efficacy in intraocular pressure (IOP) reduction and safety of the smallest gel stent (XEN 45 Gel Stent) microincisional glaucoma surgery combined with microincisional cataract surgery (MICS). by Carolyn B. Hebson, MD. Patients and Methods: Single surgeon, observational cohort study of 25 consecutive Ivantis Hydrus microstent insertions, with a minimum follow-up of 12 months. It is a well known that cataract surgery lowers intraocular pressure by as much as 30%. It forms part of the new trend towards minimally invasive glaucoma surgery (MIGS). Stent inject + cataract surgery effective in reducing IOP, burden ... study to determine the safety and efficacy of this second-generation trabecular microbypass stent that was implanted during cataract surgery. There is no difference in the cataract procedure beyond this and no difference in the post operative management. Cataract surgery alone on an eye with glaucoma will sometimes lower the pressure in the eye. Following surgery, the intraocular pressure is re-evaluated and it is sometimes possible to reduce the amount of glaucoma medication required. Managing Pseudoexfoliation During Cataract Surgery W hen performing cataract surgery on an average patient, we know there’s a 99.9-percent chance everything will go beautifully. The fluid in the bleb is absorbed naturally by the body, lowering eye pressure. In fact, in some cases, cataract surgery can lower high eye pressure, reduce the number of medications you need to manage your glaucoma, or possibly eliminate your need for glaucoma medication altogether. When to Have Combined Cataract and Glaucoma Surgery. it … In these cases, it is best to do the glaucoma surgery and delay cataract surgery until later. In clinical trials, the device reduced eye pressure in adult patients with mild-to-moderate open-angle glaucoma and … It forms part of the new trend towards minimally invasive glaucoma surgery (MIGS). In the past, glaucoma and cataract surgery were two separate procedures. The iStent drainage implant cannot be used:  In patients with narrow-angle glaucoma and certain other secondary glaucomas. In these cases, cataract surgery alone or cataract surgery with MIGS may be the best option. Whilst the device could theoretically be implanted in any patient with glaucoma, is is currently only TGA approved for use in the course of a cataract operation. It has been proven in global clinical trials to lower eye pressure, which resulted in a reduction of glaucoma medicine and, in some patients, eliminated the need for medication. iSTENT INJECT® Treatment for Glaucoma during Cataract Surgery. CONTRAINDICATIONS. NEW ORLEANS — The CyPass Micro-Stent procedure for glaucoma can be safely combined with cataract surgery, according to 2-year results from … Sometimes a cataract is not causing vision problems, but the glaucoma needs to be treated. This is because the anterior chamber will be maximally deep as the lens has been removed. The Hydrus Microstent is a revolutionary new therapy used during cataract surgery to help manage your glaucoma. Your ophthalmologist removes your eye’s cloudy lens and replaces it with an artificial one. The stent comes pre-loaded on an introducer which grips the stent. A multicenter randomized clinical trial (the Tube Versus Trabeculectomy or TVT Study) was conducted in patients who had previous surgery, including, trabeculectomy and/or cataract surgery. iStent is a … As such it is a good way to manage a patient who has concomitant glaucoma and cataract. Surgery isn’t usually the first step to treat glaucoma, but it may save your eyesight if other treatments don’t work.
