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.

Corneal diseases limited to anterior stroma are amenable to treatment. Mitomycin C MMC is used as an adjunctive treatment to prevent recurrences.

Phototherapeutic keratectomy

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.
