Understanding the Risks of LASIK Eye Surgery

LASIK eye surgery has been a transformative procedure for millions, offering a fast and effective way to correct vision. However, like any medical procedure, it comes with its set of risks and potential complications. It’s crucial for patients to be fully informed about these risks to make educated decisions about their eye care. This article delves into the risks associated with LASIK, providing a comprehensive overview to help prospective patients weigh the benefits against the possible downsides.

Common Side Effects of LASIK Surgery

Immediately following LASIK surgery, patients may experience a range of side effects, most of which are temporary and mild. These include:

  • Dry Eyes: A decrease in tear production can occur, leading to eye discomfort and blurred vision. Typically, this condition is temporary and can be managed with lubricating eye drops.
  • Glare and Halos: Some patients report seeing halos around lights or experiencing glare at night. These visual disturbances usually improve within a few weeks or months after surgery.

Less Common But Serious Risks of LASIK

While rare, there are more serious risks associated with LASIK that patients should be aware of:

Infection and Inflammation

The risk of infection is low thanks to sterile surgical techniques, but it’s a potential complication of any surgery, including LASIK. Symptoms can include redness, pain, and discharge from the eye.

Undercorrections, Overcorrections, and Astigmatism

  • Undercorrections occur when the laser removes too little tissue from the eye, leading to incomplete vision correction.
  • Overcorrections are the result of too much tissue being removed.
  • Astigmatism can be caused by uneven tissue removal and may require additional surgery or corrective lenses.

Long-Term LASIK Complications

For most people, LASIK results are long-lasting. However, a small percentage of patients might experience long-term complications, such as:

Chronic Dry Eye Syndrome

For some, dry eyes persist long after the initial recovery period, potentially affecting the quality of life and requiring ongoing treatment.

Vision Loss or Changes

Very rarely, surgical complications can lead to a loss of vision that can’t be corrected with glasses, contact lenses, or further surgery.

Mitigating the Risks of LASIK

Choosing a qualified and experienced surgeon can significantly reduce the risk of complications. Patients should undergo a thorough pre-operative evaluation to ensure they are suitable candidates for LASIK. Following post-surgery care instructions meticulously is also crucial for a smooth recovery.

Is LASIK Right for You?

Deciding to undergo LASIK surgery is a personal choice that should be made based on a careful consideration of the potential benefits and risks. For many, the chance to experience clear vision without the need for glasses or contact lenses outweighs the rare risks associated with the surgery.


While LASIK eye surgery offers a compelling solution for vision correction, it’s not without its risks. By understanding these potential complications and taking steps to minimize them, patients can make informed decisions about their eye care. With advancements in technology and surgical techniques, LASIK remains a safe and effective option for those seeking to improve their vision.
