What are the advantages and disadvantages of the PRK surgery?
PRK was the most common vision correction intervention for quite a long period of time. It is a completely safe procedure, which uses excimer laser directly on the surface of the cornea. The vision correction by laser lasts a lifetime, and the outcome is outstanding. Nearsighted and farsighted patients can both benefit from PRK. The disadvantage of the surgery is that it causes discomfort and can even be painful in the first few days after the treatment.
