10 Common Lasik Eye Surgery Side Effects

Lasik eye surgery side effects

Lasik eye surgery is a popular specs-removal procedure that aims to correct vision problems and reduce the need for glasses or contact lenses. It involves reshaping the cornea, the clear front part of the eye, using a laser. While Lasik surgery can be highly successful in improving vision, it is important to be aware of the potential lasik side effects that may occur after the procedure.

In this article, we will discuss 10 common lasik eye surgery side effects and guide on how to manage them effectively. If you are considering Lasik surgery or have recently undergone the procedure, this article will help you understand what to expect and how to navigate any potential lasik surgery complications.

Understanding Lasik Eye Surgery

Before delving into the lasik side effects, it is important to have a basic understanding of the procedure itself. Lasik stands for Laser-Assisted in Situ Keratomileusis, and it is a type of refractive surgery that aims to correct common vision problems such as nearsightedness, farsightedness, and astigmatism.

During Lasik surgery, a thin flap is created on the cornea using a microkeratome or femtosecond laser. This flap is then lifted to expose the underlying corneal tissue, which is reshaped using an excimer laser. The cornea is reshaped to improve the way light enters the eye, which in turn improves vision.

The entire procedure typically takes about 10 to 15 minutes per eye and is performed on an outpatient basis. Most patients experience improved vision within a few days after surgery.

Importance of Knowing Side Effects of Lasik Surgery

While Lasik surgery can be highly beneficial for many individuals, it is crucial to have a comprehensive understanding of the potential lasik side effects and risks involved. By being aware of these risks of lasik surgery, you can make an informed decision about whether Lasik surgery is the right choice for you.

Additionally, knowing the possible lasik eye surgery side effects will help you recognize and manage any complications that may arise after the procedure. It is important to remember that not everyone will experience these side effects, and the severity can vary from person to person.


10 Common Side Effects of Lasik Surgery

  • Dry Eyes: One of the most common lasik surgery side effects is dryness of the eyes. This occurs because the procedure can disrupt the normal tear film on the surface of the eye, leading to decreased tear production. Symptoms may include a gritty or burning sensation, redness, and blurred vision. Using artificial tears and following the recommended post-operative care instructions can help alleviate dry eye symptoms.


  • Glare and Halos: Some patients may experience glare and halos around lights, especially at night. This can make it difficult to drive or perform tasks in low-light conditions. These visual disturbances are usually temporary and improve over time as the eyes heal.


  • Sensitivity to Light: After Lasik surgery, you may experience increased sensitivity to light, known as photophobia. This sensitivity can make it uncomfortable to be in bright environments. Wearing sunglasses and avoiding excessive exposure to bright lights can help manage this lasik side effect.


  • Fluctuating Vision: It is common for vision to fluctuate during the healing process after Lasik surgery. This can include periods of clear vision followed by periods of blurriness. It may take a few weeks for vision to stabilize.


  • Eye Discomfort: Some patients may experience mild to moderate eye discomfort or irritation after Lasik surgery. This can include feelings of dryness, scratchiness, or foreign body sensation. Using lubricating eye drops as recommended by your surgeon can help alleviate these symptoms.


  • Undercorrection or Overcorrection: In some cases, the desired vision correction may not be fully achieved after Lasik surgery. This can result in undercorrection or overcorrection of the refractive error. In such cases, additional treatments or enhancements may be needed to fine-tune the results.


  • Regression: After the initial healing period, some individuals may experience regression, where the vision gradually returns to its pre-surgery state. This can occur due to natural changes in the cornea over time. 


  • Infection: While rare, there is a risk of infection after Lasik surgery. It is important to follow proper hygiene practices and use prescribed eye drops to minimize this risk. Signs of infection include increased pain, redness, discharge, and vision changes.


  • Epithelial Ingrowth: In some cases, the outer layer of cells on the cornea, called the epithelium, may grow abnormally under the corneal flap. This can cause blurry vision and discomfort. If epithelial ingrowth occurs, your surgeon may need to lift the flap and remove the cells.

  • Corneal Ectasia: Although rare, corneal ectasia is a serious complication that can occur after Lasik surgery. It involves a weakening of the cornea following LASIK, which can lead to distorted vision. The weaker cornea bulges and takes an irregular shape that blurs the vision. With proper preoperative screening, this complication can be minimized.


It is important to note that these lasik eye surgery side effects are generally rare and most patients experience successful outcomes. However, it is crucial to discuss any concerns or questions with your surgeon before undergoing the procedure.

Lasik Side Effects – Symptoms and Management

Understanding the symptoms of Lasik surgery side effects is essential for managing them effectively. 


Dry Eyes: Use artificial tears as recommended by your surgeon and avoid exposure to dry or dusty environments.

Glare and Halos: Avoid driving at night if the glare and halos affect your vision till the time your eyes adjust to different lighting conditions.

Sensitivity to Light: Wear sunglasses and limit your exposure to bright lights.

Fluctuating Vision: Avoid making any changes to your glasses or contact lens prescription till the time your vision stabilizes.

Eye Discomfort: Follow the recommended post-operative care instructions and use lubricating eye drops to alleviate discomfort.

Undercorrection or Overcorrection: Discuss any vision concerns with your surgeon to determine if additional treatments are necessary.

Regression: Attend regular follow-up visits with your surgeon to monitor any changes in vision and address any concerns.

Infection: Follow proper hygiene practices and report any signs of infection to your surgeon immediately.

Remember, every individual’s experience with Lasik surgery can be different, and it is important to consult with your surgeon for personalized advice and guidance.


Risk Factors and Precautions

While Lasik eye surgery is generally safe and effective, there are certain laser eye surgery risk factors and precautions to consider:

Age: The ideal candidate for Lasik surgery is over 18 years old, as the eyes need to be fully developed.

Stable Prescription: Your prescription should be stable for at least one year before undergoing Lasik surgery.

Good Overall Eye Health: It is important to have healthy eyes free from conditions such as glaucoma, cataracts, and severe dry eye.

Realistic Expectations: Understanding the limitations of Lasik surgery and having realistic expectations about the outcomes is crucial.

Follow Post-Operative Care: Adhere to the post-operative care instructions provided by your surgeon to ensure proper healing and minimize the risk of complications.
