Typically talking, ideal PRK candidates:
- Are 18 or older
- Have healthy eyes
- Have had a consistent vision prescription for the last year
- Do not have a disease that might impair healing
You might pick PRK over LASIK if you are having thin corneas, it will not accommodate the production of corneal scars, a flap, or an additional element that disqualifies you from LASIK surgery. Laser eye surgeons from Kraff Eye Institute will go over these considerations during your consultation.
PRK vs LASIK
The major difference between PRK and LASIK is the development of the corneal flap. Throughout a LASIK procedure, the cosmetic surgeons develop a flap externally of the cornea utilizing the femtosecond laser. Those flaps allow the cosmetic surgeons to check the deeper surfaces of the cornea, and they reshape it utilizing laser according to your specific treatment strategy.
Throughout a PRK procedure, specialists will eliminate the external layer of cells over the cornea, known as the epithelium, rather than producing a flap. While this might appear daunting, the cells grow back within a couple of days. After the cells are got rid of, the deeper layer of the cornea is reshaped to remedy aesthetic mistakes.
In addition to these differences, both treatments are quite similar. During LASIK, as well as PRK you can anticipate that:
- Numbing decreases will be applied to your eyes to reduce any type of prospective discomfort.
- You will stare at an emphasis light that assists your eyes to preserve the correct positioning.
- Your eyes will be delicately held open with a gadget that prevents you from blinking during the surgical procedure.
- The treatment will last about 15 minutes.
When executed by knowledgeable laser eye surgeons utilizing technology, PRK can use a similar visual result as LASIK. But you are going to experience a longer time for recovery after PRK compared to after LASIK because of the elimination of the epithelium.
Healing After PRK
New post-operative medicines, as well as special bandage contact lenses, are fairly efficient in dealing with the possible pain experienced by some PRK patients. Surgeons have located that:
- Almost 80% of clients experience no pain after surgical treatment.
- 2% of PRK people experience discomfort that can be aided by new medicines.
- Around 18% experience a scratchy feeling equivalent to having an eyelash below a contact lens.
Undergoing PRK, your eyes can become a little bit light-sensitive or watery for a couple of weeks after surgery. The best visual changes occur throughout the initial week while the surface cells are re-growing on the cornea. Your vision might use up to a month to stabilize.
