LASIK surgery is a method for treating vision issues such as nearsightedness and farsightedness. This procedure uses light energy to reshape your cornea and provide improved vision. But how exactly does it work? 

Below you can learn more about the LASIK procedure and what you can expect from your laser vision surgery.

What Is LASIK?

LASIK is the most commonly performed laser eye surgery with hundreds of thousands of operations being conducted each year. LASIK is a type of refractive surgery, meaning it helps to resolve refractive eye issues. Caused by the shape of your eye, refractive eye issues are the most common type of vision problem. Laser vision correction is a great option for those looking to reduce their need for glasses or contact lenses. LASIK eye surgery is typically used to treat the following vision concerns:

  • Myopia – Nearsightedness or problems seeing things up close
  • Hyperopia – Farsightedness or problems with distance vision
  • Astigmatism – An imperfection in the shape of your eye leading to blurry vision
  • Presbyopia – The gradual loss of close-up vision

How Does LASIK Work?

LASIK stands for Laser-Assisted In Situ Keratomileusis. That might sound a bit intimidating, but it basically means surgery to reshape the cornea of the eye using a laser. LASIK laser eye surgery works by targeting the laser at specific areas of the cornea to remove tissue, helping to reshape it. By reshaping the cornea, your eye surgeon can improve your eye’s ability to properly refract light rays, helping to clear up blurred vision. Below you can learn the specific adjustments that go into correcting your vision:

Treating Myopia

To treat myopia, the curvature of the cornea is reduced by removing more tissue from the center of the cornea than the edges.

Treating Hyperopia

To treat hyperopia, the curvature of the eye is increased by removing more tissue from the edges of the cornea than the center.

Treating Astigmatism 

To treat astigmatism, tissue causing the imperfection in the shape of your cornea is removed.

What Can I Expect During Laser Vision Surgery?

If you’re considering getting LASIK eye surgery, you should first familiarize yourself with what you can expect to happen during the procedure. Your eye surgeon can talk you through everything you need to know about LASIK, but a general overview of the procedure can be found below:

  • Measuring Your Eye – Before your laser vision surgery, your eye will be carefully measured.
  • Creating a Flap – A laser tool, the FS200 Femtosecond Laser, is used to painlessly create a flap on the surface of your eye.
  • Vision Correction – Light energy from the EX500 Excimer Laser is used to reduce corneal tissue in specific areas to reshape your cornea.
  • Returning the Flap – The created flap is laid back into place to begin healing.
  • See the Difference – You can expect to return to normal activities after just a few days!

Here at Gelman Vision, we pride ourselves on providing the most comfortable setting possible for our patients to receive care. You can expect to experience minimal discomfort during your laser treatment.

What Tools Do We Use to Conduct Laser Eye Surgery?

In addition to the FS200 Femtosecond Laser and EX500 Excimer Laser, the LASIK procedure at Gelman Vision also relies on the use of the WaveLight Refractive Suite. This is a state-of-the-art system that allows for incredibly precise and patient-specific outcomes using highly accurate data capture. The system is used to gather precise data about your eye before that data is used to make vision corrections.

How Long Do the Results of LASIK Last?

LASIK is a permanent vision correction procedure, but your eyes will still be subject to the same age-related changes as anyone else. This means that, for most people, the effects of LASIK surgery can be expected to remain optimal for around ten years. The amount of time before your vision begins to re-degrade can vary depending on the age of the patient. Laser eye surgery remains a great option for those looking for long-lasting vision improvements.
