If you have both cataracts and glaucoma, cataract surgery can help improve your vision and, in some cases, lower your eye pressure (intraocular pressure or IOP). However, because glaucoma affects the optic nerve, your surgery needs to be carefully planned. Here’s what you need to know about cataract surgery if you have glaucoma.

How Does Glaucoma Affect Cataract Surgery?

Glaucoma is a condition that damages the optic nerve, often due to high eye pressure. Cataract surgery can sometimes help lower eye pressure, especially in people with angle-closure glaucoma, by improving fluid drainage inside the eye. However, glaucoma can make cataract surgery more challenging. For instance:

• Some glaucoma patients have smaller pupils, making it harder to access the cataract.
• Long-term glaucoma or previous glaucoma surgeries can weaken the support structures of the eye, requiring extra care during surgery.

Can Cataracts and Glaucoma Be Treated Together?

Yes! If your glaucoma is not well-controlled, your doctor may recommend combining cataract surgery with a glaucoma procedure. This could involve placing a small device (like a stent) to improve fluid drainage in the eye, helping to lower eye pressure. These combined procedures are often safe and effective, reducing the need for glaucoma medications.

What to Expect After Surgery?

After surgery, your doctor will monitor your eye pressure closely. Cataract surgery can significantly improve your vision; some patients may require fewer glaucoma medications afterwards. However, glaucoma is a lifelong condition, so regular check-ups are still essential to protect your vision. Talk to your eye doctor about your options. Cataract surgery can address both cataracts and glaucoma, helping preserve your vision and improve your quality of life. By carefully planning your treatment, it can also address glaucoma.
