Phototherapeutic keratectomy (PTK) is one of the latest advances in eye care for the treatment of corneal dystrophies, corneal scars, and certain corneal. NOTE: Phototherapeutic keratectomy (PTK) should not be confused with photorefractive keratectomy (PRK). Although technically the same procedure, PTK is. Abstract:: Purpose: To compare the effectiveness of primary treatment of lattice corneal dystrophy with excimer laser phototherapeutic keratectomy (PTK) versus.

Also, PTK was shown to be safe and effective in children for visual improvement phototherapeutic keratectomy relief of symptoms of pain, irritation and photophobia. Systemic diseases such as uncontrolled diabetes, collagen vascular diseases like rheumatoid arthritis, and phototherapeutic keratectomy lupus erythromatosus may have delayed epithelial healing.
Corneal diseases limited to anterior stroma are amenable to treatment. Mitomycin C MMC is used as an adjunctive treatment to prevent recurrences.
Symptoms are similar to a corneal abrasion and include: What does the procedure involve? In PTK the first layer of the cornea, the epithelium, is removed using an alcohol solution, the excimer laser is applied to the eye removing a thin layer.
In theory, this provides a more sound base layer for healing of the erosion, allowing the corneal epithelium cells phototherapeutic keratectomy heal all in one sheet, making the healing phototherapeutic keratectomy more complete over the entire surface.
After the surgery a contact lens bandage is put in place to provide a healing environment and reduce pain.

Many patients with lattice suffer phototherapeutic keratectomy visual compromise due to these anterior stromal deposits. PTK has been shown to be a successful treatment for anterior corneal lesions. Traditionally, Phototherapeutic keratectomy has been the primary treatment of choice for patients with lattice corneal dystrophy.
