Excimer Laser Surgery

Excimer Laser Surgery

Excimer laser surgery is a type of laser surgery commonly used to correct refractive errors of the eye. This procedure aims to correct eye defects such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism (blurry vision), and presbyopia (age-related difficulty seeing up close and far away).

Laser Devices:

Excimer laser surgery is performed using a special laser device that allows the laser light to precisely shape eye tissues.

Procedure:

The patient’s eye surface is opened with a thin flap (layer), usually created with a microkeratome or femtosecond laser.

The excimer laser reshapes the tissues beneath the cornea, allowing light to focus properly inside the eye.

The procedure is usually carried out under local anesthesia.

LASIK and PRK:

Excimer laser surgery is applied with two main methods: LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy).

While LASIK involves the creation of a flap, PRK involves vaporizing the corneal surface with a laser after removing the surface’s epithelium instead of creating a flap.

Trans-PRK: In this method, there’s no need to separately remove the epithelium on top of the cornea. The laser device vaporizes and removes it all.

Refractive Errors:

Excimer laser surgery can correct a range of refractive errors, including myopia, hyperopia, and astigmatism.

Recovery Process:

LASIK patients generally have a faster recovery process, as they experience less pain due to the creation of a flap.

The recovery process for PRK patients may take a bit longer.

Risks and Complications:

Like any surgical procedure, excimer laser surgery carries risks. These risks can include problems with night vision, dry eyes, and light sensitivity.

Excimer laser surgery can be considered a suitable treatment option following a comprehensive assessment by an ophthalmologist and in light of information shared between the patient and doctor. Every patient is different, so consulting a specialist to determine the most appropriate treatment option is important.
