Ptk Surgery. This surgery uses a laser to treat eyesight problems which are mainly diseases of the surface of the cornea. This surgical technique uses uv light and laser technology to reshape and restore the cornea.
Some surgeons prefer to remove the epithelium with the excimer laser trans ptk. Ptk works by removing these specific irregularities allowing the cells to regenerate more smoothly and revealing a cornea that is better able to focus light. This surgical technique uses uv light and laser technology to reshape and restore the cornea.
Ptk stands for photo therapeutic keratectomy.
The usual technique is to debride the loose epithelium manually. The cornea is the smooth clear window of the eye in front of the colored iris that helps bend light rays so they focus directly on the retina the light sensing layer of cells at the back of the eye. The objective of ptk in the treatment of recurrent erosions is to remove enough of the superficial bowman s layer to permit formation of a new basement membrane with adhesion structures. Ptk stands for photo therapeutic keratectomy.
