Thinking about undergoing corrective eye surgery to improve your vision? Not sure which laser surgery is right for you?

LASIK and PRK laser eye surgeries are two of the most common forms of vision correction. While they both are safe, effective and carry a very high rate of satisfaction, they are performed differently and offer different advantages.

LASIK Eye Surgery

LASIK (laser assisted in situ keratomileusis) surgery corrects myopia, hyperopia and astigmatism. It entails creating a flap of corneal tissue that consists of a surface layer of cells, epithelium, and the stroma. The flap is created by placing a suction ring on the eye for 20 seconds using a Zeimer femtosecond laser. After the flap is created, it is flipped back to shape the cornea. After shaping, the flap is placed back down smoothly and in proper positioning.

LASIK Advantages
After undergoing LASIK, patients will immediately have better vision. They’ll also be able to resume normal activities the next day. Other advantages:

  • Long Lasting Results
  • No More Glasses or Contacts

PRK Eye Surgery

PRK (photorefractive keratectomy) surgery was the first laser eye surgery developed for vision correction. PRK also corrects myopia, hyperopia and astigmatism, however there is no flap created during surgery.

PRK is performed by removing the outer layer of the cornea and letting the cells regenerate after surgery (quickly grows back in a few days). After removing the outer layer, a laser is used to reshape the cornea. A clear contact lens bandage is placed over the eyes until the cornea has healed.

PRK is used when the adequacy of the corneal thickness is borderline, or patients do not want a flap due to their occupation (military/professional fighters).

PRK Advantages
While not as popular as LASIK, PRK is still commonly performed and offers a few advantages over LASIK in addition to achieving long lasting results and improved vision.

  • Less Corneal Tissue is Used
  • Highly Accurate in Correcting Nearsightedness

Whether you need LASIK or PRK laser surgery, it is best to consult with a board-certified ophthalmologist before undergoing any form of surgery.
