Photorefractive Keratectomy (PRK)
Photorefractive keratectomy (PRK) is a type of refractive surgery that uses a laser to treat vision problems caused by refractive errors. This procedure involves using a laser to change the shape of the cornea, which improves the way light rays are focused on the retina. PRK is commonly used to treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The goal of PRK is to correct refractive errors and improve vision, potentially reducing or eliminating the need for eyeglasses or contact lenses.
Candidate Criteria
To be a candidate for PRK, individuals need to meet certain requirements, such as having a stable prescription in their glasses or contact lenses, being over the age of 21, and having an overall normal anatomy of the eye and cornea. PRK may be a good choice for individuals with dry eyes, thin corneas, or a very active lifestyle, as it does not involve cutting a flap in the cornea like LASIK and similar surgeries do.
Risks and Recovery
As with any surgical procedure, PRK carries certain risks, including the possibility of undercorrection or overcorrection of vision. However, PRK is known for its short recovery time and low risk of vision-threatening complications. The procedure involves a short recovery period and can improve nearsightedness, farsightedness, or astigmatism.
In summary, PRK is a laser eye surgery that aims to correct refractive errors and improve vision, potentially reducing or eliminating the need for corrective eyewear. It is a suitable option for individuals with specific eye conditions or lifestyle considerations, and it offers a short recovery time with low risk of complications.
