Corneal Topography in Contact Lens Practice

Videokeratoscopy has proved an invaluable clinical tool in allowing a better understanding of corneal topography and how this varies in the general population. Its value is significant in the area of refractive surgery and in the diagnosis and monitoring of some corneal disorders. A further potential application of videokeratoscopy is in the area of contact lens fitting and after care, and some systems already include a contact lens module in their software. The software can show the contact lens to cornea fitting relationship in a number of ways and can store and present both clinical information and contact lens data which is helpful to the practitioner. This article reviews the means by which the systems may help the clinician working in the area of contact lens fitting and follow-up care.
