Photo Refractive Keratectomy (PRK)
Photo refractive keratectomy is often referred to as PRK. This type of vision corrective procedure was the first of its kind, invented even before laser-assisted-in-situ keratomileusis, also referred to as LASIK. Although LASIK is performed most often, PRK offers many advantages over a LASIK procedure for many individuals. This procedure is designed to help patients suffering from vision problems by correcting the following:
- Myopia (Nearsightedness)
- Hyperopia (Farsightedness)
Most often, an ophthalmologist will recommend a patient to take advantage of a PRK procedure if they have thin corneas.
The PRK Procedure
PRK is similar to a LASIK procedure. During LASIK, an eye surgeon will make a flap in your cornea using a device called WaveLight FS200. However, during a PRK procedure, the eye surgeon will gently remove the outer epithelial layer before the laser treatment. This process will reshape the cornea by allowing the laser to enter and focus on the retina of the eye. Following the PRK procedure, the epithelial layer of the cornea will regenerate. In most cases, patients will receive a prescription for additional drops and medications, which are designed to help them heal and remain comfortable during recovery.
The Benefits of PRK
Although many patients choose LASIK over PRK, PRK does come with benefits that are not available through a LASIK procedure. Below is a list of benefits a PRK procedure can offer:
- This procedure does not go as deep as a LASIK treatment
- This procedure is optimal for patients with thin corneas
- The procedure has fewer risks since there are no corneal flap risk complications
- This procedure has a lesser risks of compromised corneal thickness
