Corneal topography is a technique which measures the surface of your cornea. The instrument produces a very detailed map of the shape and power of the cornea which is the major refracting surface of the eye. Using computerized imaging technology a three dimensional map aids the optometrist in diagnosing and monitoring various visual conditions.
This is a quick painless easy test to perform. The images enable us to detect conditions that would be invisible to most conventional testing. Topography is essential for the pre-operative evaluation for any refractive surgery procedures as well as fitting contact lenses.
