PRK – Photorefractive Keratectomy is one of laser option in case of thin cornea if patient is not fit for Lasik Surgery. PRK permanently changed the shape of central cornea using the laser to remove by vaporization a small amount of tissue from the eyes. But for PRK surgery is applicable in case your corneas is thin and pupils grown relatively larger coupled with acute near-sightedness. If your eyes structure has gained this state, you qualify for a PRK surgery but not for LASIK one. Patient should be with the following criteria’s:-
- Patient with normal health,
- minimum 18 years of age
- Having consistent prescription for a minimum of one year,
- not in the state of pregnancy
- Accepted the possible risks during and post PRK surgery
- No other medical issues that could lead to infections or allergies.
- After you qualify all these criteria, you are eligible for PRK surgery.
PRK Surgery patients experience little discomfort in the first 24 to 36 hours after surgery and sensitivity to light. The PRK surgery process is so quick that it can be completed even in less than fifteen minutes and the patient can leave the clinic after he has rested for a short while. The main benefit of this kind of surgery is that there is no cornea flap created in a PRK as in the case of LASIK surgery. When you undergo a LASIK, the cornea flap heals up automatically but if any injury is caused to the LASIK cornea, it needs to be immediately repaired by a trained ophthalmologist. But after a PRK, you absolutely do not have to worry about the cornea.
After the PRK surgery, you should be accompanied by someone so that he/she drives you home because you would be bandaged contact lenses in order to protect the cornea until the cells redevelop after the PRK. In the PRK surgery, the recovery takes a little longer as compared to LASIK treatment. After three or four days, the contact lenses would be removed and you would now able to take eye drops for moisturising and the antibiotics course for faster healing.
In case you are not sure which eye correction surgery to undergo, there is need of conducting prior tests in order to decide the most suitable eye surgery for vision correction according to the existing state of eyes. But after the surgery, your eyes would be as normal as before, once they recover after the treatment.
