Phototherapeutic keratectomy (PTK) is a type of eye surgery technology used by a London eye doctor to treat diseases and scars on the corneal surface. A common misconception about PTK is that it’s used to improve vision, but this is not the case. Those who want to address eye scars and diseases and address a vision problem at the same time may also need to undergo a photorefractive keratectomy procedure.
What makes PTK different from PRK and LASIK?
PTK focuses more on medical benefits and less on improving eyesight. The problems that ETK is meant to solve are associated with diseases that affect the cornea, whereas PRK and LASIK are more related to the eye’s refractive issues. Examples of diseases and conditions that PTK can treat include corneal dystrophy, epithelial erosion syndrome, and scarring of the cornea. PRK and LASIK can treat and astigmatism presbyopia.
