Combined Cataract Surgery and MIGS
Understanding Combined Cataract Surgery and MIGS
MIGS procedures are designed to lower eye pressure with less trauma and faster recovery than traditional glaucoma surgeries. When combined with cataract surgery, these techniques add only a few minutes to the overall procedure and can deliver meaningful benefits for patients with both conditions.
During combined surgery, we first remove the cloudy lens and replace it with a clear artificial lens, just as we would in standard cataract surgery. Then, using the same small incision or a nearby entry point, we place a tiny device or create a microscopic drainage pathway to improve fluid outflow from your eye.
By enhancing drainage, MIGS lowers intraocular pressure, which is the primary goal of glaucoma treatment. These procedures target the drainage angle inside your eye and require careful examination of that anatomy before surgery. Devices such as the iStent, Hydrus Microstent, and techniques like the Kahook Dual Blade are designed to be gentle on eye tissue and cause less disruption than older surgical methods.
Scheduling a single surgery saves you time, reduces your overall recovery period, and means fewer days away from work or family responsibilities. You also avoid the stress and cost of undergoing two separate procedures.
Many patients appreciate the convenience of one surgery, one anesthesia session, and one set of postoperative restrictions. Treating both conditions together can also reduce your long-term need for glaucoma medications, though not everyone achieves complete medication freedom.
Several MIGS approaches are available and commonly used during combined surgery. Different devices work through different mechanisms to improve fluid drainage and lower eye pressure.
- Trabecular bypass stents like iStent that create a pathway through the drainage meshwork
- Scaffold devices such as Hydrus Microstent that expand the drainage canal
- Excisional techniques like Kahook Dual Blade that remove tissue blocking drainage
- Suprachoroidal approaches that create a new drainage route between layers of the eye
- Subconjunctival microshunts for controlled outflow in select cases
Our eye doctors will recommend a specific device or technique based on your type of glaucoma, your drainage angle anatomy, how much pressure reduction you need, and your individual treatment goals. Not every option is appropriate for every glaucoma type or angle structure.
The cataract portion of your surgery remains the same, with removal of the cloudy lens and placement of a clear artificial lens. The MIGS portion adds only a few extra minutes to the overall procedure time.
Because we address glaucoma during the same operation, your postoperative eye drop regimen may include additional anti-inflammatory medications for a short period. Your follow-up schedule will focus on monitoring both your vision clarity and your intraocular pressure to ensure both conditions are well controlled.
For patients who need extended medication delivery or more sustained pressure reduction, we may consider advanced options such as Durysta or iDose. These technologies provide continuous glaucoma medication delivery inside the eye, reducing the burden of daily drops.
Our team evaluates each patient individually to determine whether these technologies are appropriate based on your glaucoma severity, medication tolerance, and treatment goals.
Who Benefits from Combined Cataract and MIGS Procedures
Not every patient with cataracts and glaucoma is a candidate for combined surgery. We carefully evaluate your eye health, disease severity, and treatment goals to determine whether this approach is right for you.
If you have been diagnosed with both cataracts and glaucoma, you may be a candidate for combined surgery. Many people develop cataracts as they age, and glaucoma also becomes more common after age sixty.
Candidacy depends on your specific type of glaucoma, the anatomy of your drainage angle, the severity of your disease, your target eye pressure, and any prior eye surgeries. Treating both conditions together can optimize your vision and protect the optic nerve from further damage.
MIGS procedures work best when glaucoma is caught early or is at a moderate stage. These devices provide modest to moderate pressure lowering, which is often enough when the disease has not yet caused severe damage.
The amount of pressure reduction we can achieve must match your individual target pressure based on the health of your optic nerve. If your glaucoma is advanced or requires aggressive pressure lowering, we may recommend a more traditional glaucoma surgery such as trabeculectomy or tube shunt placement instead.
If you already use one or more glaucoma eye drops every day, combined surgery can help reduce or eliminate some of those medications. Many patients find daily drops inconvenient, expensive, or irritating to the eye surface.
MIGS offers a way to control pressure without relying solely on drops. While you may still need some medication after surgery, the burden is often lighter, and many patients appreciate the improved quality of life that comes with fewer medications.
Even if your glaucoma is well-controlled on drops now, you might prefer to lower your dependence on medications over the years ahead. Combining MIGS with cataract surgery can help achieve that goal.
Fewer medications mean fewer side effects, lower costs, and less worry about missed doses. This benefit appeals to many patients who value simplicity and long-term convenience.
How We Determine If You Are a Candidate
Our comprehensive evaluation includes several tests and examinations to assess both your cataracts and your glaucoma. We use advanced diagnostic technology to make informed recommendations about whether combined surgery is right for you.
We measure your intraocular pressure at every visit using tonometry, a quick and painless test. Tracking your pressure over time helps us understand how well your current treatment is working and whether additional intervention makes sense.
If your pressure remains above target despite medications, or if we see fluctuations that could harm the optic nerve, combining MIGS with your cataract surgery may offer better control.
Visual field testing maps your side vision to detect any blind spots caused by glaucoma. During the test, you look into a machine and press a button each time you see a light, and the computer analyzes the pattern of your responses.
Results help us stage your glaucoma and decide whether a MIGS device will provide enough pressure lowering. Severe visual field loss may indicate that a more aggressive surgical approach is needed instead.
We examine your optic nerve using a special microscope and often take high-resolution images with optical coherence tomography, or OCT. These images reveal thinning of the nerve tissue and help us track any changes over time.
OCT imaging provides detailed measurements of the nerve fiber layer and helps us assess the current health of your optic nerve before surgery. This baseline information is essential for monitoring your progress after the procedure.
Not every cataract needs immediate surgery, so we evaluate how much the cloudiness affects your daily life. If your vision is good enough for safe driving and reading, we may recommend waiting.
When the cataract is ready for removal and you also have glaucoma, that is the ideal moment to combine procedures. We align the timing to benefit both conditions and minimize your overall burden.
We review every glaucoma drop you use, how well your pressure is controlled, and any side effects you experience. If you use multiple drops or struggle with the regimen, MIGS becomes more appealing.
Understanding your medication history also helps us predict how much additional pressure lowering you might need and which MIGS device or technique will work best for your situation.
Your overall medical history matters because certain conditions can affect healing or increase surgical risk. We ask about diabetes, autoimmune diseases, blood thinners, and any previous eye surgeries or injuries.
This information helps us tailor our surgical plan and ensure we choose the safest and most effective approach for your individual circumstances.
What to Expect During Combined Surgery
Understanding what happens on surgery day can help ease any anxiety and prepare you for a smooth experience. We will guide you through each step and answer any questions before your procedure.
We will provide detailed instructions about which medications to take or skip on the morning of surgery and when to stop eating or drinking. Following these instructions carefully helps ensure your safety during the procedure.
Arrange for someone to drive you home afterward, since your vision will be blurry and you cannot drive the same day. Wear comfortable clothing and leave jewelry and valuables at home.
You will lie comfortably on a reclining surgical bed while we clean the area around your eye and apply sterile drapes. A microscope helps us see the tiny structures inside your eye as we work.
First, we remove the cloudy cataract through a small incision and insert the new artificial lens. Then, using the same or a nearby incision, we place the MIGS device or create the drainage pathway. Throughout the procedure, you remain awake but relaxed under light sedation.
Most patients receive numbing eye drops and a mild sedative to keep you calm and comfortable. You will not feel pain during the surgery, though you may sense light pressure or hear quiet sounds from the surgical instruments.
We monitor your comfort throughout the procedure and can provide additional medication if needed. Our goal is to make the experience as easy and stress-free as possible.
Cataract surgery alone typically lasts fifteen to twenty minutes. Adding the MIGS portion extends the total time by only a few minutes, so the entire combined procedure usually finishes in under thirty minutes.
After surgery, you rest briefly in a recovery area while the sedation wears off, and then you go home the same day. There is no overnight hospital stay required for this procedure.
Risks, Side Effects, and Limitations
As with any surgical procedure, combined cataract surgery and MIGS carries some risks. Understanding these potential complications helps you make an informed decision and know what to watch for during recovery.
Many patients experience mild and temporary side effects in the first days or weeks after combined surgery. These effects are usually manageable and improve as your eye heals.
- Transient blurred vision or fluctuating vision clarity
- Hyphema, or a small amount of blood in the front chamber of your eye
- Light sensitivity and glare or halos around lights
- Foreign body sensation or mild discomfort
- Transient eye pressure elevation or fluctuation
These side effects typically resolve within days to weeks and rarely cause lasting problems. We monitor you closely during follow-up visits to ensure your eye is healing properly.
Although rare, more serious complications can occur with any eye surgery. We use advanced surgical techniques and careful monitoring to minimize these risks, but it is important to be aware of them.
- Infection inside the eye, known as endophthalmitis
- Persistent inflammation or swelling
- Corneal edema or risk of corneal decompensation in susceptible eyes
- Significant or prolonged eye pressure spike
- Device obstruction, malposition, or migration
- Peripheral anterior synechiae or angle closure
- Choroidal effusion or hemorrhage
- Need for additional glaucoma surgery
- Vision-threatening complications, though very rare
If you experience any concerning symptoms during recovery, contact our office immediately so we can evaluate and treat any complications promptly.
MIGS procedures offer many benefits, but they also have limitations. Understanding what these devices can and cannot achieve helps set realistic expectations.
Pressure reduction with MIGS is often modest to moderate rather than dramatic. Results vary by device, individual anatomy, and healing response. Some patients will continue to need glaucoma medications after surgery, and others may require additional glaucoma procedures in the future if pressure rises or the disease progresses. For medication-refractory glaucoma or advanced disease requiring aggressive pressure lowering, we may recommend traditional procedures like trabeculectomy or tube shunt surgery instead.
Recovery and Follow-Up Care After Combined Surgery
Your recovery after combined surgery is similar to recovery from cataract surgery alone, with a few additional considerations for glaucoma management. Following your postoperative instructions carefully helps ensure the best possible outcome.
Your vision will be blurry immediately after surgery, and you may see halos around lights or notice mild redness. These effects improve quickly over the first day or two as your eye begins healing.
Mild discomfort, a gritty feeling, or light sensitivity are normal. Resting with your head elevated and wearing the protective shield we provide, especially while sleeping, helps protect your eye during this early phase.
We prescribe antibiotic drops to prevent infection and anti-inflammatory drops to reduce swelling. You may also continue or adjust your glaucoma medications depending on your pressure readings after surgery.
Use drops exactly as prescribed, even if your eye feels fine. Wait at least five minutes between different drop types, wash your hands before touching the bottle or your eye area, and keep track of doses with a written schedule if needed.
Avoid heavy lifting, bending over, or straining for at least one week, since these activities can raise eye pressure temporarily. You should also skip swimming, hot tubs, and dusty or dirty environments until we clear you, typically one to two weeks after surgery.
Most patients return to light activities like reading or watching television within a day or two. Driving is allowed once your vision is clear enough and we confirm it is safe, often within a few days to a week.
Your first follow-up visit usually happens within one to two days after surgery. We check your vision, measure your eye pressure, and examine the surgical site to ensure everything is healing properly.
Additional visits occur over the next few weeks and months to monitor pressure trends and adjust medications if needed. Long-term success depends on keeping your pressure in a safe range and watching for any signs of glaucoma progression.
Although serious complications are rare, certain symptoms require urgent evaluation. Call our office immediately or seek emergency care if you notice any of these warning signs.
- Sudden decrease in vision or new floaters and flashes
- Severe eye pain or headache
- Worsening pain with worsening vision that does not improve day to day
- Increasing redness, swelling, or discharge
- Marked light sensitivity or a cloudy or hazy cornea
- Nausea or vomiting along with eye discomfort
Prompt evaluation and treatment can prevent serious complications and protect your vision.
Frequently Asked Questions
Patients considering combined surgery often have similar questions about the procedure, recovery, and outcomes. These answers provide additional guidance to help you make an informed decision.
Adding MIGS to cataract surgery does introduce certain additional risks, though the overall safety profile remains favorable for most patients. You may have a higher chance of temporary bleeding in the front of the eye, short-term eye pressure fluctuations, or inflammation compared to cataract surgery alone. The specific risks depend on the type of MIGS device or technique we use and your individual eye anatomy. We will discuss these risks with you in detail so you can weigh the benefits and make an informed decision about your care.
Laser treatments such as selective laser trabeculoplasty, or SLT, and laser peripheral iridotomy, or LPI, are options for some patients with glaucoma. SLT can lower eye pressure by improving drainage through the trabecular meshwork, while LPI treats narrow angles that could lead to angle-closure glaucoma. These laser procedures can be performed in the office and do not require surgery, but they may not provide enough pressure lowering for everyone. We will discuss whether laser treatment, MIGS, or traditional surgery is the best choice based on your specific type of glaucoma and pressure control needs.
Most MIGS devices provide sustained pressure reduction for several years, though the exact duration varies by procedure, device, and individual healing. Some patients maintain good pressure control for five years or longer, while others may see a gradual rise over time due to scarring, obstruction, or disease progression. Regular follow-up helps us catch any changes early and adjust treatment if needed, whether that means adding medications or considering additional procedures.
If your pressure remains above target after combined surgery, we have several options. We can add or increase glaucoma medications, consider additional laser treatment to enhance drainage, or discuss a second glaucoma procedure such as trabeculectomy or tube shunt surgery if necessary. Some patients with medication-refractory glaucoma may need more aggressive intervention even after MIGS. The goal is always to protect your optic nerve and preserve your vision long term, and we will work with you to find the right approach.
Several alternatives exist depending on your individual situation. You may choose cataract surgery alone, which can lower eye pressure modestly in some patients. Continuing or adjusting glaucoma eye drops is another option, as is laser treatment such as SLT to improve drainage. For more advanced glaucoma, traditional filtering surgery such as trabeculectomy or a tube shunt may be more appropriate. Some patients prefer a staged approach, having cataract surgery first and then a separate glaucoma procedure if needed later. We will review all suitable options with you and help you choose the path that best fits your goals and medical needs.
Most insurance plans, including Medicare, cover medically necessary cataract surgery and MIGS procedures when appropriate criteria are met. Coverage depends on the severity of your cataracts, your glaucoma diagnosis, and the specific MIGS device or technique used. Our team will verify your benefits and help you understand any out-of-pocket costs before your surgery. Advanced options like Durysta or iDose may have different coverage rules, and we will discuss those details with you if they are part of your treatment plan.
