Phototherapeutic Keratectomy or PTK surgery is performed with an excimer laser. PTK surgery can take from 10 seconds to 5 minutes; during this period laser beam removes the superficial layer of the cornea or epithelium. The patient is given special anaesthetic eye drops to reduce the risks and discomfort or pain during the procedure.
Generally PTK procedure is indicated for the following: to remove scars, smooth the surface of the cornea, treat corneal erosion or reshape the cornea, which has been disfigured due to an accident or surgery. PTK removes the diseased part of the cornea. It is expected to improve vision and general feeling of comfort in the eye.
The operations are performed by surgeon Dr Kai Noor and Dr Inger Heleen Viikna.
