Photorefractive keratectomy (PRK) is a non-invasive refractive procedure that involves using a UV excimer laser on the cornea following the removal of the corneal epithelium. It is effective and has low rates of patient dissatisfaction. PRK does not need to create a corneal flap, thus reducing complications for patients with thin corneas or wide pupils. Among the postoperative complications are pain, corneal haze, epithelial healing issues, and infection. Long-term complications include regression of refractive error, dry eye syndrome, corneal ectasia, and late postoperative infections. Effective management will consist of intraoperative techniques and postoperative care that focuses on controlling pain, prevention of corneal haze, and dealing with any complications promptly. The simple nature and safety profile associated with PRK has made it an ideal option for vision correction with high patient satisfaction rates.

摘要

Photorefractive keratectomy (PRK) is a non-invasive refractive procedure that involves using a UV excimer laser on the cornea following the removal of the corneal epithelium. It is effective and has low rates of patient dissatisfaction. PRK does not need to create a corneal flap, thus reducing complications for patients with thin corneas or wide pupils. Among the postoperative complications are pain, corneal haze, epithelial healing issues, and infection. Long-term complications include regression of refractive error, dry eye syndrome, corneal ectasia, and late postoperative infections. Effective management will consist of intraoperative techniques and postoperative care that focuses on controlling pain, prevention of corneal haze, and dealing with any complications promptly. The simple nature and safety profile associated with PRK has made it an ideal option for vision correction with high patient satisfaction rates.
