Understanding the Side Effects of Common Myopia Correction Surgeries

Myopia, or nearsightedness, is a common vision condition that affects millions of people worldwide. Advancements in medical technology have made it possible to correct myopia through various surgical procedures. However, like all surgeries, myopia correction operations come with their own set of potential side effects. This article delves into the side effects associated with the most common myopia correction surgeries: LASIK, PRK, and LASEK, providing you with the information needed to make an informed decision about your eye health.

the Side Effects of Common Myopia Correction Surgeries

LASIK (Laser-Assisted In Situ Keratomileusis)

LASIK is one of the most popular eye surgeries for correcting myopia. It involves reshaping the cornea using a laser to improve vision. While LASIK is known for its quick recovery times and excellent results, it can have side effects, including:

  • Dry Eyes: Many patients experience dry eyes for several months after surgery. This occurs because the procedure can disrupt the production of tears.
  • Glare and Halos: Some individuals may notice increased sensitivity to light, along with halos or glare around lights at night, which can be particularly distracting while driving.
  • Under or Overcorrection: In some cases, the amount of corneal tissue removed might not be perfect, leading to under or overcorrection of vision. Additional surgery may be required to correct this.
  • Flap Complications: The creation of the corneal flap during LASIK can lead to complications such as infection or abnormal healing.

PRK (Photorefractive Keratectomy)

PRK predates LASIK and involves removing the outer layer of the cornea before reshaping the underlying corneal tissue with a laser. Side effects of PRK include:

  • Longer Recovery Time: Compared to LASIK, the recovery from PRK is typically longer. The outer layer of the cornea needs time to heal, which can take several days to a few weeks.
  • Pain: Patients often report more discomfort and pain during the initial healing process after PRK compared to LASIK.
  • Visual Fluctuations: Vision can fluctuate for several weeks or months following PRK as the eye heals.

LASEK (Laser-Assisted Sub-Epithelial Keratomileusis)

LASEK combines elements of LASIK and PRK, where the epithelial layer is loosened and moved aside before reshaping the cornea with a laser. Side effects can include:

  • Epithelial Healing: Similar to PRK, LASEK requires time for the epithelial layer to heal, which can lead to discomfort and blurred vision during the recovery period.
  • Dry Eyes: Like LASIK, dry eyes are a common side effect of LASEK, though typically less severe.


While myopia correction surgeries offer a promising solution for improved vision, it’s crucial to consider the potential side effects. Discussing these procedures with a qualified ophthalmologist can help you weigh the benefits against the risks. Remember, the right choice varies from person to person, depending on individual health, lifestyle, and the specifics of one’s vision impairment.
