The Photorefractive Keratectomy (PRK) is a kind of laser eye surgery. The PRK procedure was introduced before the LASIK. The PRK is also used to correct vision problems which include astigmatism, nearsightedness or farsightedness.
Surgeons stress that the PRK is a surface procedure on the eye. With this, there is no risk of complications of surgical flaps. Unlike LASIK, this procedure does not involve creating a thin flap on the surface of the eye. PRK is also the better choice for people that have cornea which are very thin to undergo a LASIK eye surgery.
Who should undergo PRK?
Your surgeon will know best what type of eye surgery you should undergo. The first thing to consider is your corneal tissue. The thickness of a patient’s cornea is a very critical issue. If you require massive eye correction, this would mean more tissue ablation. Your surgeon will judge if you will have enough residual corneal tissue so that the tissue ablation might be operated safely.
Another thing to consider is the condition of the eyes. Are you experiencing eye problems or diseases? This might affect the stability and the ability of the cornea to heal well after the operation. The surgeon will perform a thorough background check on your medical history to ascertain if you had medical history that might hamper a good outcome of the operation.
Another factor that should be considered is the age of the patient. If for example the patient is in the childhood or early teen years, the vision error may not yet stabilize and correcting the refractive eye problem by undergoing PRK may lead to under correction. You will have to wait for a couple of months or years before undergoing the operation.
How to prepare for a PRK surgery?
The surgeon performs initial eye tests to the patient to determine if PRK is the right surgical operation for him. The eye doctor may ask you not to wear contact lenses several weeks or days before the operation and the initial eye tests. This stage is important so that the cornea will be in its natural state when examined and operated by the doctor.
After the surgeon declares that you are to undergo PRK, prepare yourself for the operation and ensure that you have your post-operative medicines ready.
