PTK Eye Surgery in London (Phototherapeutic Keratectomy)
Phototherapeutic Keratectomy (PTK) is a specialised laser procedure used to treat surface-level corneal diseases, scarring, and recurrent erosions. It gently removes abnormal tissue to improve comfort, smoothness, and visual clarity.
What Is Phototherapeutic Keratectomy (PTK)?
PTK is a medical laser eye procedure that removes damaged or irregular corneal tissue caused by conditions such as corneal scars, dystrophies, keratoconus, or recurrent corneal erosion syndrome. Unlike LASIK or PRK, which are performed for refractive correction, PTK is a therapeutic intervention aimed at restoring the natural transparency and smoothness of the corneal surface.
PTK uses an excimer laser to precisely ablate superficial layers of the cornea, removing opacities and irregularities that distort vision or cause pain. It is especially effective in treating recurrent corneal erosion syndrome and managing early stages of keratoconus, often improving both comfort and clarity.
