What Are the Different Types of Laser Eye Surgery?

Laser eye surgery involves reshaping the cornea to correct farsightedness, nearsightedness and astigmatism (blurred vision due to the defective curvature of the cornea). Successful surgery results in the elimination of the need for wearing glasses or contact lenses. The technique uses safe laser beams to make incisions for the purpose of vision correction. The process provides effective results with minimum complications.

However, the following are not eligible for laser eye surgery:

* Those below 18 years of age.
* Expecting or breastfeeding women.
* Those with chronic autoimmune ailment or conditions that obstruct healing.
* Those on medications that impact vision or healing.
* People with serious eye inflammation, damaged corneas or very large pupils.

According to the American Optometric Association reports, nearly 33% Americans suffer from some degree of nearsightedness. Studies also reveal that more than 20% children between the ages 12 and 17 face difficulty in seeing the blackboard.

Types of Laser Eye Surgery

The recent advancements in the medical field have led to the development of several types of laser eye surgery. Your doctor will prescribe you the surgery most suitable for your eye condition. Some common laser eye operations are:

LASIK

LASIK (Laser-Assisted in Situ Keratomileusis) is one of the most common types of laser eye operation. In this procedure, a microkeratome metal blade is used to cut the cornea flap. Then, an excimer laser is used to reshape the medial cornea layer (stroma). You may experience some blurriness in the first 24 hours. However, your vision will improve within a few weeks.

LASEK

The LASEK (Laser Assisted Sub-Epithelial Keratomileusis) procedure is quite similar to Lasik. However, a thinner layer of cornea is lifted away in this procedure. First the epithelium is softened and removed. Then, an excimer laser is used to reshape the stroma. This procedure is less invasive and recommended for patients with very thin corneas.

PRK

PRK (Photo Refractive Keratectomy) is recommended for patients with low-to-moderate refractive errors. The procedure starts with the removal of a thin layer of epithelium. Then, an excimer laser is used to correct the shape of the cornea. The exposed portion of the cornea grows back in the recuperation period. The patient experiences improved vision with the passage of time. However, this procedure has become less popular after the introduction of LASIK technique. The lengthy healing process is the main reason for its reduced popularity.
