Do Eye Injections Hurt?

This is one of the most common worries in retina care, because the idea of a needle going into the eye is understandably alarming, and fear of pain leads some people to hesitate or avoid treatment they need. Patients want honest reassurance about what it actually feels like before they agree to start. The good news is that the reality is almost always much gentler than the mental picture.

An eye injection delivers medicine through the white of the eye (the sclera) into the vitreous gel, using a very fine needle, in a procedure that takes only seconds. Because the eye is numbed first, the sensitive surface does not register the needle as sharp pain; most people feel a moment of pressure and then it is done.

What you feel afterward comes mostly from the surface of the eye, not the injection deep inside. The antiseptic used to prevent infection can leave the eye feeling dry and scratchy for several hours, and the small needle site can make the eye a bit sore. These sensations are temporary and are a normal part of healing, not a sign that something is wrong.

Before an injection, the eye is prepared carefully. Numbing is achieved with anesthetic drops, a gel, or sometimes a small amount of anesthetic applied with a cotton tip or injected just under the surface, so the eye is genuinely desensitized. The eye and lids are cleaned with povidone-iodine antiseptic to prevent infection, a small lid holder keeps you from blinking, and the medicine is injected through the sclera in seconds. The needle used is very fine.

Most of the discomfort people report is not from the injection but from the antiseptic prep, which can leave a burning, dry, or gritty feeling for a few hours as the surface recovers. A small subconjunctival hemorrhage, a red blood spot on the white of the eye, sometimes appears at the injection site; it looks dramatic but is harmless and fades over a week or two.

Pain tolerance varies, and some injections or some eyes feel more than others. Patients who are especially anxious can talk with their doctor about extra numbing steps. Over the course of repeated treatments, most people find the process becomes routine and less stressful as they learn what to expect.

Mild, short-lived discomfort after an injection is normal. What is not normal is pain that increases over the hours and days afterward rather than settling down, especially when combined with worsening vision, growing redness, light sensitivity, or a burst of new floaters.

Those symptoms can be early signs of a serious infection inside the eye (endophthalmitis) or another complication, and they require same-day contact with your eye doctor. Sudden, severe vision loss or the sensation of a curtain over your vision should prompt urgent care right away.

Comfort is part of the process, so the doctor and team confirm the eye is adequately numb before proceeding and can add more anesthetic if you feel too much. At follow-up or if you call with discomfort, the ophthalmologist examines the eye to distinguish ordinary post-injection soreness and antiseptic-related irritation from a real complication, checking vision, eye pressure, the surface of the eye, and the retina. If pain is worsening, they look specifically for signs of infection or inflammation inside the eye so it can be treated promptly.

For the routine scratchiness and mild soreness after an injection, over-the-counter artificial tears or lubricating drops are the mainstay and soothe the surface irritation from the antiseptic. Acetaminophen can be used if you want something for mild soreness. A cool compress may help, and symptoms typically fade within a day.

If you tend to feel injections more than average, your doctor can adjust the numbing approach at future visits, using stronger or additional anesthetic. The most important point is that manageable discomfort is not a reason to stop needed treatment; the injections protect vision, and the comfort measures make the process very tolerable for the great majority of patients.

• Do not avoid or delay a needed injection out of fear of pain, since the eye is numbed and the discomfort is usually minor and brief.
• Do not rub the eye afterward, which can worsen irritation; use lubricating drops instead.
• Do not assume worsening pain over the next day or two is normal, increasing pain with redness or blurred vision needs same-day evaluation.
• Do not use leftover or non-prescribed medicated drops after an injection unless your doctor tells you to; plain artificial tears are what soothe the surface.
• Do not panic over a red blood spot on the white of the eye, it is usually harmless and clears on its own.

If you are anxious about an upcoming injection, ask so the team can walk you through the numbing and what to expect; patients in the Hanover area receive this care at May Eye Care Center. After an injection, call the same day if you have increasing pain, worsening or blurred vision, growing redness, light sensitivity, or a shower of new floaters, and seek emergency care for sudden severe vision loss.

Eye injections usually hurt much less than patients expect because the eye is numbed first, with only mild, short-lived soreness or grittiness afterward; the temporary discomfort should not stand in the way of treatment that protects your vision.
