Why Does Blurry Vision Happen After Laser Iridotomy?

Post-laser iridotomy vision problems can include blurry vision. Experts at a reputed eye hospital, experts explain why this happens, how long it lasts, and what to do if it persists.

Laser iridotomy is a common and effective procedure used to treat or prevent angle-closure glaucoma. By creating a tiny hole in the iris, it helps fluid drain properly, reducing intraocular pressure (IOP) and preventing optic nerve damage.

However, many patients experience temporary vision problems after the procedure, including blurry vision, glare, halos, and sensitivity to light. While these symptoms are usually not a cause for concern, they can be distressing if you don’t know what to expect.

This article will cover:

  • Why blurry vision happens after laser iridotomy
  • How long it typically lasts
  • What you can do to manage and improve your vision
  • When you should seek medical attention

By understanding post-laser iridotomy vision problems, you can navigate your recovery with confidence and ensure the best possible eye health.

What Is Laser Iridotomy and Why Is It Performed?

What Is Laser Iridotomy?

Laser iridotomy is a minimally invasive laser procedure used to treat or prevent angle-closure glaucoma, a serious condition where the eye’s drainage system becomes blocked, causing a dangerous rise in eye pressure.

During the procedure:

  • A laser is used to create a tiny hole in the iris (the colored part of the eye).
  • This hole allows fluid (aqueous humor) to flow more freely, reducing eye pressure.
  • It prevents glaucoma attacks and long-term vision damage.

Who Needs Laser Iridotomy?

Your eye specialist may recommend a laser iridotomy if you:
✅ Have narrow-angle glaucoma or are at high risk of developing it
✅ Experience sudden eye pain, blurred vision, or headaches due to high IOP
✅ Have been diagnosed with chronic angle-closure glaucoma
✅ Want to prevent a glaucoma emergency before it happens

The procedure is generally quick and safe, but temporary side effects, such as post-laser iridotomy vision problems, can occur.

Why Does Blurry Vision Happen After Laser Iridotomy?

1. Inflammation and Swelling

  • The laser disrupts the iris tissue, triggering a mild inflammatory response.
  • This inflammation can cause temporary swelling and clouding of vision.
  • Eye drops (steroids or anti-inflammatory drops) help speed up healing.

2. Light Scatter and Halos

  • The small hole created in the iris can cause light to scatter abnormally, leading to:
    • Halos around lights
    • Increased glare
    • Mild light sensitivity
  • This effect is usually temporary as the brain adjusts to the new light flow.

3. Temporary Increase in Eye Pressure

  • Some patients experience a temporary rise in intraocular pressure (IOP) after the procedure.
  • Increased pressure can cause:
    • Blurred vision
    • Headaches
    • Eye discomfort
  • Your doctor may prescribe IOP-lowering eye drops to prevent this.

4. Corneal Edema (Swelling of the Cornea)

  • The laser’s heat can cause temporary swelling in the cornea, leading to a foggy or blurred appearance.
  • Corneal swelling usually resolves within a few days.

5. Tear Film Disruption and Dryness

  • Laser treatment can cause temporary tear film instability, leading to:
    • Dry eyes
    • Mild irritation
    • Blurry vision
  • Using artificial tears helps restore eye moisture and clarity.
