The PRK (photorefractive keratectomy) procedure was actually developed before LASIK. With PRK, Dr. Kelly uses a laser to reshape the cornea just like LASIK does, but PRK is an ablation technique, which means the laser is used to remove tissue from the cornea’s outer surface. By contrast, in the LASIK procedure, a portion of the cornea is lifted away from the eye, and the tissue beneath it is altered. 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:
- Thin corneas
- Oddly shaped corneas
- Cornea is steep in contour
- Patient suffers from lazy eye (amblyopia)
Full vision correction with PRK can take several weeks to become apparent. Like LASIK, many people who undergo PRK achieve vision of 20/20 or better. The results you can expect will be discussed with you during your initial consultation.
