Abstract:
Phototherapeutic keratectomy(PTK)has been employed as a surgical tool to treat corneal disease for about 20 years.PTK made it possible to remove superficial corneal opacities and thereby restore vision by splitting molecules of biological tissue with 193 nm ultraviolet light.Recently,the development of the excimer laser technique is more rapid.It has principally focused on refractive surgery but has also benefited PTK.Anterior corneal pathology,such as elevated lesions,stromal opacities,corneal scars,corneal dystrophies and corneal degenerations etc,can be visually devastating.Over the past decade,there was a shift in the treatment of these conditions from corneal transplantation to PTK for visual restoration.PTK is a powerful tool for the management of anterior corneal pathology.In a properly selected and well-counseled patient,PTK can significantly improve vision and quality of life.This article reviews the recent literature of techniques for performing and refining PTK and also of various pathologic conditions that can be treated with PTK.
