LASIK vs PRK Eye Surgery Compared

LASIK vs PRK eye surgery compared: Ask Dr. Rohr which may be right for you.LASIK and PRK are two of the most common laser-assisted corrective eye surgeries available. Both can be used to correct nearsightedness, farsightedness, and astigmatism. But what’s the difference?

LASIK Explained

LASIK (Laser-Assisted In-Sutu Keratomileusis) is a vision correction treatment that uses a laser to reshape the surface of the eye’s cornea. The cornea is the transparent part of the coat of the eyeball that covers the iris and pupil. A very thin flap of the cornea is peeled back, then a laser is used to shape the remainder of the cornea beneath it. The flap is placed back over the “shaped” portion, and the surgery is complete.The benefit of LASIK is that because the shaped part of the cornea lies beneath the eye’s cornea flap, the cornea heals very quickly. In most cases, a person will recover from LASIK surgery within 24 hours, and begin driving, using a computer or reading within 1 day.

PRK Explained

PRK (Photo-Refractive Keratectomy) is the use of a laser to gently reshape the outer surface of the cornea. The same laser surgery equipment and techniques are used. However, because surgery is performed on the outside of the eye, longer healing times are required. The cornea typically heals in 3-4 days. However, it may take up to a week for the cornea to completely heal. A special, protective contact lens will be left on the eye to protect the cornea during the first 3-4 days, and then removed by Dr Rohr in a follow-up visit.The benefit of PRK is that there is no corneal flap. Without a flap, there is much less risk of flap-related complications. Although corneal flap-related complications are very rare, they can occur in patients who inadvertently rub their eyes and dislodge the flap during healing. Fortunately, a dislocated flap can be easily fixed by Dr. Rohr.

Which is Better?

Both LASIK and PRK have produced successful results for millions of adults. However, it takes a qualified eye surgeon like Dr Rohr at the Rohr Eye & Laser Center in Grand Blanc, Michigan to determine which is best for you.
