If you have been told you have both a cataract and glaucoma, you are far from alone. The two conditions become more common with age, and they frequently appear in the same eye. The good news is that they often do not have to be treated separately. For many patients, the cataract can be removed and the glaucoma addressed during a single procedure, using a tiny device called a stent. This guide explains how combined surgery works, who tends to be a candidate, and what recovery is like, so you can walk into a consultation with informed questions.
A cataract is a clouding of the eye's natural lens that develops slowly over years. Glaucoma is a separate condition in which pressure inside the eye damages the optic nerve, the cable that carries vision to the brain. They are unrelated diseases, but they share a big risk factor: getting older. Because both are more likely after age sixty, it is common for one eye to have early cataract changes and glaucoma at the same time.
There is also a practical overlap. Cataract surgery is one of the most common procedures in medicine, and the eye's drainage system sits right next to where the cataract is removed. That anatomy is what makes it possible to treat both problems through the same small opening, in one sitting, rather than scheduling two operations.
Combined surgery has two parts that happen back to back during the same visit. Understanding each part helps the whole procedure feel less mysterious.
First, the clouded natural lens is gently broken up and removed, then replaced with a clear artificial lens called an intraocular lens, or IOL. This is standard modern cataract surgery. It is typically done with numbing drops, takes well under an hour, and does not require an overnight stay.
Once the new lens is in place, the surgeon can address the glaucoma using a category of techniques known as minimally invasive glaucoma surgery, often shortened to MIGS. One of the most widely used options is the iStent, a micro-scale device, smaller than a grain of rice, that is placed into the eye's natural drainage channel. By holding that channel open, it helps fluid drain more easily and lowers the pressure inside the eye. Because the stent works with your eye's own anatomy, it adds only a few minutes to the operation and does not change the recovery in a way most patients notice.
The goal is not simply convenience, though a single recovery instead of two is a real benefit. The larger aim is to protect the vision you have. Here is what the approach is designed to do:
Combined cataract and stent surgery is generally considered for adults who have a visually significant cataract along with mild to moderate open-angle glaucoma, the most common form. It is not right for everyone. The type and severity of glaucoma, the health of the drainage system, and your overall eye anatomy all factor into the decision. Some patients with more advanced glaucoma are better served by a different procedure. The only way to know what fits your eyes is a thorough evaluation, which is why the surgical plan is always tailored to the individual rather than chosen from a menu.
Recovery from combined surgery closely resembles recovery from cataract surgery on its own. Most people are back to light daily activities within a day or two and use a short course of prescription drops to prevent infection and control inflammation while the eye heals. Vision often begins to sharpen within the first week, though it can take several weeks to fully settle. Your surgeon will ask you to avoid rubbing the eye, heavy lifting, and swimming for a defined period, and will see you for follow-up visits to confirm both the vision and the eye pressure are where they should be.
Good outcomes depend on more than the operation itself. In most cases your journey starts with your optometrist, a valued partner who provides your routine exams, updates your glasses, and is often the first to notice that a cataract or rising pressure needs a closer look. When surgery is appropriate, Dr. Mudgil performs the procedure and then coordinates the follow-up care with your optometrist, who continues to manage your ongoing eye health and prescriptions close to home. This shared model means you keep the provider who knows your eyes while also having a surgeon focused on the operation.
No. Glaucoma is a chronic condition that is managed rather than cured. The aim of adding a stent during cataract surgery is to lower eye pressure and help slow the progression of the disease, which protects the vision you still have. Ongoing monitoring remains important even after a successful procedure.
It depends on the lens you choose and the health of the rest of your eye. Many patients reduce their dependence on glasses for some tasks, but results vary from person to person, and glaucoma can affect the vision outcome. Your surgeon will talk through realistic expectations for your specific eyes during the consultation.
No. The device is microscopic, sits inside the eye's drainage system, and is not visible or noticeable once it is in place. It requires no cleaning or maintenance and is designed to stay put permanently.
Not necessarily. Some patients choose to have cataract surgery alone and manage glaucoma separately with drops or other procedures. Combining the two is an option worth discussing because it can address both concerns with a single recovery, but the right sequence is a personal decision made with your surgeon.
If you are living with both a cataract and glaucoma, you have more choices than you may realize. A consultation is the best way to learn whether combined surgery fits your eyes, and how it connects to our approach to advanced cataract surgery.
