Glaucoma Surgery

Glaucoma Treatment

Protect the vision you
still have — without the drops.

Glaucoma doesn't announce itself — it takes peripheral vision slowly, silently, and permanently. Dr. Malitz offers the full range of modern glaucoma treatments, from in-office laser to micro-implants that can reduce or eliminate daily eye drops entirely. The goal: stop progression and keep you seeing clearly, with the least burden on your daily life.

Understanding Glaucoma

The "silent thief" — and why early treatment matters

Glaucoma damages the optic nerve, usually because of elevated eye pressure (intraocular pressure, or IOP). The damage is irreversible — but progression can be stopped with treatment.

👁 It's more common than people think

Glaucoma affects over 3 million Americans, but half don't know they have it — and of those, half were seen by an eye doctor in the past five years and the diagnosis was missed. There are no early symptoms. By the time you notice vision loss, significant damage has already occurred.

Are you at risk?

You're at higher risk if you have a family history of glaucoma, elevated eye pressure, diabetes, thin corneas, myopia (nearsightedness), or are of African-American descent. Risk also increases after age 60. If any of these apply, regular screening is essential — even if your vision seems fine.

🎯 The goal: lower eye pressure

Glaucoma damages the optic nerve — the structure that carries visual information to the brain. Every treatment works by reducing intraocular pressure to slow or stop further nerve damage. The target pressure is different for every patient.

Advanced diagnostic technology

Dr. Malitz uses visual field testing, optic nerve scanning (OCT), and corneal thickness measurement (pachymetry) to detect glaucoma earlier and track progression more precisely than a standard eye exam. These tools let us catch changes before you notice symptoms — and adjust treatment before damage occurs.

Treatment Approach

How Dr. Malitz approaches glaucoma treatment

Treatment is stepwise and personalized. We start with the least invasive option and escalate only when necessary.

1
Eye drops
Prescription drops to lower IOP. Effective for many patients, but requires daily compliance and can cause side effects (redness, stinging, lash growth).
2
SLT laser or Durysta
In-office treatments that reduce or eliminate daily drops. SLT improves natural drainage; Durysta is an implant that releases medication inside the eye for months.
3
MIGS or surgery
Micro-implants (iStent, Xen) or tissue removal (Kahook) to create permanent drainage pathways — often combined with cataract surgery.

Not every patient needs surgery

Many glaucoma patients are well-controlled with drops or laser alone. Dr. Malitz will evaluate your optic nerve health, visual field, and pressure trends before recommending any procedure. If you don't need surgery, he'll tell you — and manage you medically or comanage with your optometrist.

Procedures We Offer

Every modern glaucoma treatment, under one roof

Dr. Malitz is trained in the full spectrum of glaucoma procedures — from laser to micro-implants to advanced filtering surgery. Here's what we offer.

In-office · No downtime

SLT — Selective Laser Trabeculoplasty

A gentle laser applied to the eye's drainage tissue to improve natural fluid outflow. SLT is performed in the office, takes about 5 minutes per eye, and requires no incision. It can reduce or eliminate the need for daily drops, and it's repeatable if the effect wears off over time.

Drop-free · In-office implant

Durysta — Sustained-Release Bimatoprost Implant

A tiny biodegradable implant placed inside the eye during a quick office procedure. Durysta continuously releases bimatoprost — a proven pressure-lowering medication — directly inside the eye for months, eliminating the need for daily drops. Ideal for patients who struggle with drop compliance, experience side effects from topical medications, or simply want the convenience of not having to remember drops every day.

MIGS · Combined with cataract surgery

iStent Trabecular Micro-Bypass

The world's smallest medical implant — a tiny titanium stent placed in the eye's drainage channel (Schlemm's canal) to create a permanent bypass through the trabecular meshwork. Typically implanted during cataract surgery through the same incision, adding only a few minutes to the procedure. Designed for mild-to-moderate open-angle glaucoma.

MIGS · Standalone or with cataract

Kahook Dual Blade Goniotomy

A specialized blade precisely excises a strip of the trabecular meshwork — the eye's natural drain — opening a wider pathway for fluid to exit. Unlike stents, no device is left in the eye. Can be performed as a standalone procedure or combined with cataract surgery. Effective for mild-to-moderate open-angle glaucoma.

Advanced · For moderate-to-severe

Xen Gel Stent

A soft, flexible collagen-derived stent that creates a new drainage pathway from inside the eye to the subconjunctival space — similar in concept to a traditional trabeculectomy, but through a tiny ab interno approach. Offers more significant pressure reduction than trabecular MIGS. Used for moderate-to-advanced glaucoma when angle-based procedures aren't sufficient.

MIGS · Micro-drainage

Glaukos Micro-Drainage

Micro-scale drainage devices that restore the eye's natural outflow by bypassing the trabecular meshwork and improving access to collector channels. Multiple stents can be placed to reach different collector channels for greater pressure reduction. Designed to be combined with cataract surgery.

Dr. Malitz will recommend the procedure that matches your disease severity, anatomy, and whether you also need cataract surgery. Many patients benefit from combining MIGS with cataract surgery — one trip to the operating room, one recovery, two problems addressed.

Narrow-angle glaucoma? There's a laser that can cure it.

Not all glaucoma is the same. If you have narrow-angle glaucoma, a quick in-office laser procedure called Laser Peripheral Iridotomy (LPI) creates a tiny opening in the iris to restore proper fluid drainage. LPI is preventive — it can stop an acute angle-closure attack before it happens. The procedure takes minutes, requires no incision, and is covered by insurance.

A Smart Combination

Glaucoma + cataracts? One surgery handles both.

If you have both glaucoma and cataracts — which is common, since both increase with age — Dr. Malitz can address both in a single procedure.

🔄 How it works

During your cataract surgery, Dr. Malitz implants a MIGS device (like an iStent or Kahook goniotomy) through the same tiny incision. The glaucoma portion adds only a few minutes to the procedure. You recover from both at the same time.

💰 Often no extra cost

Because MIGS is performed during cataract surgery, the facility and anesthesia costs are already covered. The MIGS device and additional surgeon time are billed separately to your insurance. Most patients pay little to nothing out of pocket for the glaucoma portion.

Already had cataract surgery?

Many MIGS procedures — including Kahook Dual Blade and Xen Gel Stent — can be performed as standalone procedures in patients who have already had cataract surgery. SLT laser is also always available as a standalone treatment. Learn more about cataract surgery →

Las Vegas & Glaucoma

The desert adds risk factors your eyes don't need

Las Vegas patients face environmental conditions that can complicate glaucoma management.

☀️

UV exposure and eye pressure

Year-round intense sunlight can affect eye comfort and compliance with drop schedules. Transitioning to laser or surgical treatment can reduce dependence on drops you might be forgetting in the heat.

💧

Dry climate complicates drops

Low humidity means your eyes are already dry. Adding glaucoma drops — many of which contain preservatives that worsen dryness — compounds the problem. MIGS and SLT can reduce or eliminate the drop burden.

🏥

Full surgical capability on-site

Dr. Malitz performs glaucoma procedures at Red Rock Surgery Center, where he serves as Medical Director. No hospital visits — outpatient, efficient, and close to home.

Cost & Insurance

Glaucoma treatment is covered by insurance

Unlike elective procedures like LASIK, glaucoma is a medical condition. All treatments — from drops to laser to surgery — are covered by Medicare and most insurance plans.

🏥 What insurance covers

Medicare and most commercial plans cover the full cost of glaucoma evaluation, SLT laser treatment, and surgical procedures including MIGS devices. Your out-of-pocket cost is typically limited to copays and deductibles — not the procedure itself.

📋 What to bring to your visit

Your insurance card, a list of current eye drops and medications, and any records or visual field tests from your referring doctor. We'll verify your benefits and give you a clear estimate of any out-of-pocket costs before scheduling any procedure.

Common Questions

Frequently asked questions about glaucoma surgery

Can glaucoma be cured with surgery?
No — glaucoma cannot be cured, and vision already lost cannot be restored. But surgery can lower eye pressure effectively enough to stop further damage. The goal of every treatment is preservation: protecting the vision you still have.
What is MIGS, and how is it different from traditional glaucoma surgery?
MIGS stands for Minimally Invasive Glaucoma Surgery. Unlike traditional procedures (trabeculectomy, tube shunts), MIGS uses tiny devices or incisions, often through the same opening as cataract surgery. The tradeoff: MIGS is safer and recovers faster, but it typically produces a more moderate pressure reduction. For mild-to-moderate glaucoma, that's usually enough.
Does Medicare cover glaucoma surgery in Las Vegas?
Yes. Glaucoma is a medical condition, and all treatments — including SLT laser, iStent, Kahook, and Xen — are covered by Medicare and most commercial insurance plans. You'll typically be responsible only for your standard copays and deductibles.
Can I get glaucoma surgery and cataract surgery at the same time?
Yes — and it's one of the biggest advantages of modern MIGS. If you need cataract surgery and have glaucoma, Dr. Malitz can implant a micro-stent or perform a goniotomy during the same procedure. One anesthesia, one recovery, two conditions addressed.
Will I still need eye drops after glaucoma surgery?
Many patients are able to reduce or eliminate their glaucoma drops after MIGS or SLT. However, some patients still need one or two drops to maintain their target pressure. Dr. Malitz will monitor your pressure closely after surgery and adjust your drop regimen as needed.
What's the difference between an iStent and a Xen Gel Stent?
The iStent works by bypassing the trabecular meshwork and improving drainage through the eye's natural outflow system (Schlemm's canal). It's best for mild-to-moderate glaucoma and is typically placed during cataract surgery. The Xen Gel Stent creates an entirely new drainage pathway to the subconjunctival space — more similar in concept to a traditional trabeculectomy. It produces greater pressure reduction and is used for moderate-to-advanced disease.
How long does recovery take?
For SLT laser: no downtime. For MIGS combined with cataract surgery: recovery is the same as cataract surgery alone — most patients return to normal activities within a day or two. For Xen Gel Stent: recovery may take 1–2 weeks, with additional follow-up visits to monitor bleb function and pressure.
I've been told I need a trabeculectomy. Should I get a second opinion?
It's always reasonable to seek a second opinion before any surgery. MIGS options like the Xen Gel Stent can sometimes achieve similar results to a trabeculectomy with a better safety profile. Dr. Malitz is happy to evaluate your case and discuss all options. Learn more about second opinions →

Don't wait for symptoms that never come.

Glaucoma steals vision silently. If you've been diagnosed, have a family history, or haven't had your pressure checked in a while — schedule an evaluation. Early treatment is the difference between keeping your vision and losing it.
