PRK Method

The PRK (photorefractive keratectomy) procedure was actually developed before LASIK. With PRK, used a laser to reshape the cornea like LASIK does, but PRK is an ablation technique, which means that the laser is used to remove tissue from the outer surface of the cornea.

In contrast, in LASIK, a part of the cornea is lifted from the eye and the tissue underneath is disturbed. Because the unaltered corneal tissue is replaced over the altered cornea, acting like a natural bandage, healing is much faster after LASIK. However, PRK is more effective in certain situations, including:

Fine corneas
Strangely shaped corneas
The cornea is steep in outline
The patient suffers from lazy eye (amblyopia)
Complete vision correction with PRK can take several weeks to appear. Like LASIK, many people who undergo PRK achieve 20/20 vision or better. The results you can expect will be discussed with you during your initial consultation.

At the end of the surgery, contact lenses are worn for a few days in order to heal the surface epithelial layer more easily and to reduce the discomfort. Vision will be blurry for 3-4 days until recovery is complete. Complete normalization of vision may take several weeks, unlike Lasik.

Is There Any Risk?

There is no medical operation with zero risk. Like any operation, PRK laser has risks. Infection may occur after the operation. Non-transparent areas called permanent scars may appear in the cornea.

When Can I Back To Work?

There is no clear vision for the first 3-5 days. After the contact lens is removed, vision gradually clears. Then you can back to work.
