PRK (Photorefractive Keratectomy)

PRK (Photorefractive Keratectomy)

Photorefractive Keratectomy (PRK) is a widely used laser procedure in eye surgery. In this procedure, a thin layer of tissue on the cornea is removed using an excimer laser, and then laser light is applied to reshape the cornea. This way, when light enters the eye, it refracts better, resulting in clearer vision.

How Does It Work?

1. Surface Preparation: The eye doctor prepares the eye surface in a sterile environment, providing a painless experience with the use of anesthetic eye drops.

2. Removal of Epithelial Layer: The thin epithelial layer on the cornea is gently removed or softened with an alkaline solution.

3. Laser Application: The excimer laser reshapes the cornea according to a programmed pattern.

4. Placement of Protective Contact Lens: A protective contact lens is placed on the cornea to support the healing process.

Who Is It Suitable For?

PRK is suitable for individuals with vision defects such as myopia, hyperopia, and astigmatism. When considering laser surgery, the thickness of the cornea and overall eye health are evaluated.
