Making sense of... photorefractive keratectomy.
The technique of photorefractive keratectomy (PRK) represents a major development in ophthalmology. Using lasers, PRK involves reshaping the cornea so that its refractive power is increased. Currently PRK can only be used to correct myopia and astigmatism, but hypermetropia may also be corrected by PRK in the near future.
