PRK surgery, fully named as photorefractive keratectomy, is the predecessor of other laser surgery used to correct vision errors, such as myopia, hyperopia and astigmatism. It is a refractive surgery with an excimer laser. PRK requires longer period for healing, and there are some side effects, and glares or halos around light is most common one of them. With dilated pupil in night, the larger treatment prescription, the more chance to have these halos and starbursts. Because in PRK surgery, the surgeon won't make an incision on your cornea, instead he/she will remove the outer membrane layer of cornea, named epithelium, so usually patient with PRK surgery takes longer time to recover. During the first 6months, your vision might fluctuate because that the epithelium needs to grow back. After it grows back, you can get stable vision then. Normally this halos symptom is mild. If it is severe, I suggest you to talk to you doctor for help. The doctor might can give you any glasses with anti-reflective coating which might help reduce the glare and halos. Yet most of the cases, this vision disturbances are just temporary and normally disappear within three to six months after completely healed. So don't worry too much. Good Luck!
