LASIK and PRK are both laser eye surgeries used to correct common vision problems, but they differ in how the cornea is treated during the procedure.

LASIK involves creating a thin flap on the cornea using a microkeratome or a femtosecond laser, which is then folded back to expose the underlying cornea. The surgeon then uses a laser to reshape the cornea before replacing the flap. The flap acts as a natural bandage, which helps to promote faster healing and reduce postoperative discomfort. LASIK typically offers a faster recovery time and less postoperative discomfort than PRK.

PRK, on the other hand, involves removing the outer layer of the cornea (epithelium) before using a laser to reshape the cornea. The epithelium then regenerates over time, which can lead to a longer recovery period and more postoperative discomfort than LASIK.

The decision between LASIK and PRK depends on a variety of factors, including the specific vision problem being corrected, the thickness of the cornea, and the patient’s individual preferences and expectations. LASIK may be preferred for patients who want a faster recovery time and less postoperative discomfort, while PRK may be preferred for patients who have thin corneas or who are at higher risk of flap-related complications.

It’s important to discuss the potential risks and benefits of each procedure with your eye doctor to determine which option is right for you.
