The computed corneal topography treatment which is also referred to as computer assisted videokeratography is a diagnostic measure where a specially crafted instrument helps in projecting a series of light rings in the cornea leading to the production of color-coded map of the surface of the cornea along with its cross-section profile. The corneal topography is used to detect subtle irregularities as well as astigmatism in the corneal surface and serves to be an alternative to manual keratometry. Thus, it can be described as a non-invasive medical imaging procedure that aids in mapping the curvature in the surface of the cornea. As the cornea accounts for about 70 percent of the refractive power of the eye, the topography of this part is of critical importance for the determination of the overall health of cornea and the quality of vision. The three-dimensional eye topography helps the ophthalmologist to diagnose as well as treat several conditions such as intraocular lens implantation and planning a suitable treatment for cataract surgery and refractive surgery like LASIK so that its accurate results can be evaluated. The computed corneal topography treatment is one of the procedures that an individual has to go through before the cross-linking as well as mini asymmetric radial keratotomy for diagnosing the keratoconus and understanding the level of corneal steepness alterations in healthy relatives. This treatment has no side effects and is used by ophthalmologists and optometrists all across the world.
