Eye Injections for Macular Degeneration: What to Expect, Step by Step

Quick answer: An eye injection for macular degeneration takes a few seconds and is done in the office. Your eye is thoroughly numbed and cleaned, a small device holds your eyelids open, and the medication goes into the white of the eye with a very fine needle. Most people feel pressure, not sharp pain. The whole visit, including numbing and imaging, usually takes under an hour. Injections are typically started monthly and then spaced out, sometimes to every two to four months, based on how your eye responds.

Why are injections used?

In wet macular degeneration, diabetic macular edema, and retinal vein occlusion, a protein called VEGF drives abnormal blood vessels to grow and leak fluid into the retina. That fluid distorts and blurs central vision.

Anti-VEGF medications block that protein. The leaking dries up, and vision often stabilizes or improves. According to the American Academy of Ophthalmology, anti-VEGF treatment has transformed wet AMD from a disease that commonly caused severe vision loss into one many patients can manage for years.

What happens during the injection?

1. Check-in and imaging. You'll usually have an OCT scan so Dr. Garg can see how much fluid is present.
2. Numbing. Anesthetic drops or gel numb the surface of the eye. Some patients receive a small amount of numbing medicine under the surface.
3. Cleaning. An antiseptic (povidone-iodine) cleans the eye and lashes to prevent infection. It may sting briefly.
4. Eyelid holder. A small device keeps your eyelids open so you don't have to worry about blinking.
5. Injection. You look in one direction. The medication goes in through the white of the eye in a couple of seconds. You may see a swirl or bubble afterward. That's the medication and it fades.
6. Rinse and check. The eye is rinsed, and your vision and pressure are checked before you leave.

Does an eye injection hurt?

Most patients describe pressure rather than pain. The antiseptic can cause stinging or a scratchy feeling for several hours afterward, which is the most common complaint. Many patients say the anticipation was far worse than the injection itself, and that later visits got easier.

Tips that help:

• Tell the team if you're anxious. They can talk you through each step.
• Breathe slowly and keep your other eye open and relaxed.
• Use preservative-free artificial tears afterward if the eye feels gritty.

What's normal after an injection?

• Mild scratchiness or irritation for a day
• A small red spot on the white of the eye, which fades over one to two weeks
• A few floaters or a bubble for a day or two
• Blurry vision for a few hours

When should I call?

Call the office right away for increasing pain, worsening redness, light sensitivity, or decreasing vision in the days after an injection. These can be signs of infection or inflammation, which are rare but need prompt treatment.

How often will I need injections?

Most treatment plans start with monthly injections. Once the fluid is under control, many retina specialists use a "treat and extend" approach, gradually lengthening the time between injections as long as the eye stays dry. Newer medications like faricimab (Vabysmo) and high-dose aflibercept (Eylea HD) were designed to allow longer intervals for some patients. See Avastin vs. Eylea vs. Vabysmo.

Can I drive afterward?

If your eyes were dilated, bring a driver. Many patients bring a driver for every injection visit.
