A Complete Guide to Laser Eye Surgery

What is laser eye surgery?

Laser eye surgery is a type of vision correction procedure that reshapes the cornea, the clear front surface of the eye.

The cornea plays an important role in focusing light onto the retina. When the shape of the cornea causes light to focus incorrectly, vision can become blurry. These focusing problems are known as refractive errors.

Laser eye surgery uses highly precise lasers to alter the shape of the cornea so light focuses more accurately, helping improve vision without relying on glasses or contact lenses.

The procedure is commonly used to treat:

• Short-sightedness (myopia)
• Long-sightedness (hyperopia)
• Astigmatism

Many people choose laser eye surgery because they want greater convenience, particularly for work, sport, travel, and everyday activities.

What types of laser eye surgery are there?

Not all laser eye surgery procedures are the same.

Different technologies may be more suitable depending on your prescription, eye health, lifestyle, and visual goals.

LASIK

LASIK (Laser-Assisted In Situ Keratomileusis) is the most commonly performed laser eye surgery procedure worldwide.

During LASIK, a thin flap is created on the surface of the cornea. The underlying corneal tissue is then reshaped using an excimer laser before the flap is repositioned.

LASIK is known for its rapid visual recovery and minimal discomfort.

PRK and TransPRK

PRK (Photorefractive Keratectomy) was the original laser vision correction procedure.

Instead of creating a flap, the surface layer of the cornea is removed before laser treatment.

TransPRK is a newer version that performs the treatment without touching the eye with surgical instruments.

These procedures may be suitable for patients with thinner corneas or certain occupational requirements.

SmartSight and Lenticule Extraction

SmartSight is a flap-free laser eye surgery procedure that removes a small piece of tissue from within the cornea through a tiny incision.

Because no flap is created, some patients prefer this option for active lifestyles.

Long-sightedness (Hyperopia)

Long-sightedness can affect near vision and sometimes distance vision as well.

Laser treatment can often improve focusing ability by changing the curvature of the cornea.

Astigmatism

Astigmatism occurs when the cornea has an irregular shape.

This causes light to focus unevenly and can result in blurry or distorted vision.
