Push the button and eliminate glasses. Sounds too good to be true, and those who are in the field of photorefractive keratoplasty (PRK) know the facts remain somewhere else. Certainly there are many happy patients who are ecstatic about the elimination of most or all of their myopia. However, there are also real limits and problems, especially corneal haze and epithelial hyperplasia, that appear to be unresolvable in a minority of patients. Improving accuracy and even eliminating corneal haze and epithelial hyperplasia may be possible with time, patience, improved technology, and good scientific discovery regarding the causes of these problems.
No matter what you may think about these problems, PRK has become an "in your face" type of issue. There are many different plans that could potentially drop an excimer laser in your area, with Food and Drug Administration approval. It is hard to keep track of all of them.
