Understanding Glaucoma and Its Impact on Vision

Glaucoma is one of the leading causes of irreversible vision loss worldwide — and yet, many people don’t know they have it until damage has already begun. 

If you’ve been diagnosed with glaucoma or are being monitored for high eye pressure, you might be wondering what it means for your long-term vision, especially when it comes to procedures like cataract surgery or other vision correction options.

At LENS & LASIK by Jackman Eye Institute, we see many patients who ask the same question:

“Can I still get cataract surgery if I have glaucoma?”

The answer is often yes — and in some cases, cataract surgery can even help manage glaucoma.

What is Glaucoma?

Glaucoma refers to a group of eye conditions that damage the optic nerve, often due to increased intraocular pressure (IOP). Over time, this pressure can lead to gradual vision loss — typically starting at the peripheral edges and moving inward.

There are several types of glaucoma, but the two most common are:

• Open-Angle Glaucoma
  The most common form. It develops slowly and usually has no symptoms until vision loss occurs.
• Angle-Closure Glaucoma
  Less common, but more sudden and serious. It’s a medical emergency requiring immediate care.

Why does this matter for surgery?

Any eye procedure — especially one involving the lens or pressure regulation — needs to account for the patient’s IOP and optic nerve health. But that doesn’t mean surgery is off the table.

Can You Still Get Cataract Surgery if You Have Glaucoma?

In many cases, yes.

Cataract surgery is not only safe for many glaucoma patients — it can even lower intraocular pressure. During cataract surgery, the cloudy natural lens is replaced with a clear artificial lens. This process can improve fluid drainage in the eye, helping to relieve pressure.

At LENS & LASIK, our team customizes cataract procedures to each patient’s condition. For glaucoma patients, that might mean:

• Combining cataract surgery with a pressure-reducing procedure (like MIGS – Minimally Invasive Glaucoma Surgery),
• Choosing a specific type of intraocular lens (IOL),
• Coordinating closely with your eye specialist to track pressure pre- and post-surgery.

What About LASIK or Other Vision Correction Options?

If you’re exploring LASIK or other refractive procedures — the picture is a bit more nuanced.

LASIK

Many patients with glaucoma can safely undergo LASIK, depending on the type and severity of their condition and how well it’s being managed.

While LASIK involves a brief, temporary increase in intraocular pressure (IOP) during the creation of the corneal flap, this is not typically harmful for patients with mild or well-controlled glaucoma. 

However, one of the most important factors is the health of your optic nerve. Glaucoma can damage the optic nerve over time, and if the nerve is already compromised, your vision may be affected. That’s why your eye professional will perform specialized testing to assess your optic nerve and ensure your glaucoma is stable before recommending LASIK.

In some cases, alternative procedures like Refractive Lens Exchange (RLE) may be suggested.

Also, if you’re using glaucoma eye drops, it’s important to discuss dry eye risks, since these drops can contribute to dryness — a common side effect of LASIK.

Refractive Lens Exchange (RLE)

Refractive Lens Exchange (RLE) can be a safe and effective option for many patients with glaucoma who want to reduce their dependence on glasses. RLE involves replacing your eye’s natural lens with an artificial intraocular lens (IOL), similar to cataract surgery. This procedure can:

• Correct your vision and reduce your dependence on glasses, especially if you’re not a candidate for LASIK.
• Potentially help manage IOP, particularly in patients with narrow angles or early lens-related changes that contribute to pressure elevation. 
• Can also be combined with a MIGS (Minimally Invasive Glaucoma Surgery) procedure, that improves fluid drainage from the eye, helping to lower your eye pressure and reduce the need for glaucoma medications.

However, similar to LASIK, the health of your optic nerve is a key factor. That’s why we always begin with a comprehensive consultation — to help you understand what’s safe, effective, and tailored to your long-term vision goals.
