PRK, (PhotoRefractive Keratectomy), is used to correct myopia, hyperopia and astigmatism, In this process the epithelium (topmost layer of the cornea) is removed. Then the cornea of the affected eye is reshaped by a computer controlled eximer laser.
However, PRK has its drawbacks, too. Patients do experience discomfort for 24-
Although PRK sculpts only a tiny amount of tissue from the cornea, it is a surgical procedure and thus the outcome cannot be guaranteed. Any surgical procedure should be undertaken only after careful consideration of the likelihood of success and consequences of any possible risks or side effects. Thorough professional advice from a qualified eye surgeon or surgeons is required before any eye treatment is undertaken. Predictability can be defined in several ways-
It is also important to separate the normally expected side effects of surgery and healing from real complications. Immediately after surgery some people have discomfort, although the use of bandage contact lenses and medications usually control this nicely. Light sensitivity is almost universal and halos and other unusual light effects can occur. Vision can be reduced while healing and from the normally planned overcorrection. Medical professionals and their associates consider this treatment as experimental as longterm side effects are not yet known. You must discuss and fully understand all of these possible side effects and problems prior to surgery. Hopefully, the information here will assist you in that process.
