Corneal Topography

Corneal Topography

Of all the technology currently available, corneal topography provides the most detailed information about the curvature of the cornea. A corneal topographer projects a series of illuminated rings onto the corneal surface, which are reflected back into the instrument.The reflected rings of light are analyzed by very sophisticated computer and software and a topographical map of the cornea is generated. The color topographical map and computerized analysis reveals any distortions of the cornea, such as is keratoconus or corneal scarring, as well as the corneal curvature and meridians of astigmatism. The corneal map allows the physician to formulate a "3-D" perspective of the cornea's shape. This diagnostic procedure is essential for patients being considered for refractive surgical procedures (such as Epi-LASIK) and may even be helpful with fitting contact lenses and calculating intraocular lens power for cataract surgery.
