PRK treatment is carried out as an outpatient procedure. PRK stand for Photo Refractive Keratectomy. This technique was once very popular due to its effectiveness in treating myopia, hyperopia and astigmatism. The technique is very similar to LASIK, but the keratectomy by microkeratome is unnecessary. The surgeon will gently remove the outer layer of cells (skin) from the surface of your cornea with a hand-held instrument before treating your eye with the laser. You will hear the laser make a faint clicking sound. The whole process takes less than 15 minutes and the laser treatment itself is very brief-typically lasting for no more than 45 seconds. It is a more desirable method for patients with a thin cornea.
However, the recovery time of PRK is longer than LASIK and there is a greater risk of infection, corneal haze. Steroid eye drops must also be used for longer time and close observation and checkups are required.
* The reason is that wearing contacts lenses, for a long time, could change the curvature of the cornea, therefore the refraction have changed as well. Not wearing contact lens, for a while, will cause the shape and the curvature of eye to revert back to its natural shape, enabling us to get more precise data of the cornea.
Before the treatment, you will be given an antibiotic and anesthetic drops. Then, the surgeon will correct your vision with the chosen treatment program. After treatment, surgeon will place the eye shield over your eyes to prevent you from accidentally rubbing your eyes. The eye shields have tiny pinholes for you to see normally so you can go home and rest. The doctor will check the treatment area upon the next day to determine a proper healing process.
