Photorefractive keratectomy (PRK) is another type of refractive surgery and this kind of surgery uses a laser to cure vision problems caused by refractive errors. This means, this error does not bend light properly
In this stage, we use a laser to change the shape of your cornea and it improves the way light rays are focused on the retina. PRK is used to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
The goal of PRK Surgery is to correct your eye error to improve your vision. Further, PRK may also reduce your need for eyeglasses or contact lenses. In some instances, you may also avoid them completely.
