Corneal topography: Also known as videokeratography or corneal mapping, corneal topography is a method of computer-assisted examination of the cornea, the clear front portion of the eye that transmits and focuses light into the eye. Corneal topography is performed by projecting illuminated rings onto the corneal surface which are reflected back and measured by the instrument. The test results in the generation of a topographical map of the cornea.
Corneal topography is used to identify the curvature of the cornea and to identify distortions (such as keratoconus) or scarring of the cornea. It is also used as an aid in fitting contact lenses and in the evaluation of patients undergoing LASIK and other surgeries.
Corneal topography is a rapid, painless test that is performed in the doctor's office.
Imaging techniques of the cornea are developing rapidly, mainly because of recent advances in refractive surgery.
The visual disturbance caused by keratoconus is mainly due to the irregular shape of the corneal surface. In order to effectively follow the progression of the disease ...
