Laser Eye Surgery: How It Works and What to Expect

Posted on by Paige Spence

Laser eye surgery, also known as refractive surgery, is a revolutionary approach to addressing vision problems such as nearsightedness, farsightedness, and astigmatism. This procedure uses laser technology to reshape the cornea, the transparent front part of the eye, to improve its ability to focus light onto the retina. By doing so, laser eye surgery can significantly reduce or eliminate the need for glasses or contact lenses.

Understanding Laser Eye Surgery

The Science Behind Laser Eye Surgery

Laser eye surgery works by reshaping the cornea to correct common vision problems. The cornea, which acts as the eye’s primary focusing lens, determines how well light is bent or refracted as it enters the eye. When the cornea is misshapen, light rays do not focus properly on the retina, resulting in blurry vision.

Laser eye surgery uses a precise laser beam to remove tissue from the cornea, altering its shape and correcting refractive errors. By reshaping the cornea, the laser allows light to properly focus on the retina, resulting in clearer vision.

But how does the laser actually reshape the cornea? Well, during the surgery, the laser beam precisely removes tiny amounts of tissue from the cornea, changing its curvature. This process is guided by a computer-controlled tracking system that follows the movements of the eye, ensuring accuracy and precision. The laser used in the procedure is an excimer laser, which produces a cool ultraviolet light beam that does not generate heat. This makes it safe for use on the delicate tissues of the eye.

Different Types of Laser Eye Surgery

There are several types of laser eye surgery procedures available, and the choice depends on the specific vision problem and individual factors. The most common types include:

  1. LASIK (Laser-Assisted In Situ Keratomileusis): This is the most popular laser eye surgery technique. It involves creating a protective corneal flap, which is then lifted to allow the laser to reshape the underlying cornea. The flap is then replaced.
  2. PRK (Photorefractive Keratectomy): In this procedure, the thin outer layer of the cornea is completely removed before reshaping the underlying cornea with the laser. No protective flap is created.
  3. LASEK (Laser-Assisted Subepithelial Keratectomy): Similar to PRK, LASEK involves the removal of the superficial layer of the cornea. However, a protective flap is created and repositioned after the laser treatment.

Each type of laser eye surgery has its own advantages and considerations. For example, LASIK offers a quicker recovery time and less discomfort compared to PRK and LASEK. On the other hand, PRK may be a better option for individuals with thinner corneas or those involved in contact sports, as it eliminates the risk of flap complications. LASEK, with its protective flap, combines some of the benefits of both LASIK and PRK.

Different Types of Laser Eye Surgery

LASIK (Laser-Assisted In Situ Keratomileusis)

LASIK is the most common type of laser eye surgery. It involves creating a thin flap in the cornea, using a microkeratome or femtosecond laser, and reshaping the underlying tissue with an excimer laser. One of the main advantages of LASIK is its quick recovery time, with most patients experiencing improved vision within a day or two.

During the LASIK procedure, the patient’s eye is numbed with eye drops, and a speculum is used to hold the eyelids open. The surgeon then uses the laser to reshape the cornea, correcting nearsightedness, farsightedness, or astigmatism. The entire process typically takes less than 15 minutes per eye, making it a quick and efficient option for those looking to improve their vision.

PRK (Photorefractive Keratectomy)

PRK is an alternative to LASIK, particularly suitable for individuals with thin corneas. Instead of creating a flap, the outer layer of the cornea is completely removed using an excimer laser. The cornea is then reshaped to correct the refractive error. PRK has a longer recovery time compared to LASIK, but it can be an effective option for those who are not suitable candidates for LASIK.

After a PRK procedure, patients may experience some discomfort and blurry vision for a few days. It may take up to a week for the outer layer of the cornea to regenerate, leading to clearer vision. PRK is often recommended for individuals involved in contact sports or with occupations that pose a risk of eye injury, as there is no flap that could potentially dislodge.

LASEK (Laser Epithelial Keratomileusis)

LASEK is a hybrid of LASIK and PRK. It involves creating a thin flap in the epithelium, the outermost layer of the cornea, and subsequently reshaping the cornea with an excimer laser. LASEK may be recommended for individuals with thin corneas or those who have occupations or hobbies that increase the risk of eye trauma. Click here to learn more about epithelium.

Unlike LASIK, LASEK does not involve cutting a flap in the cornea, reducing the risk of certain complications. The recovery time for LASEK is typically longer than LASIK but shorter than PRK. Patients may experience some discomfort and sensitivity to light during the healing process, but vision improvement can be significant once the eye has fully healed.
