Process of using a camera/computer system to map the cornea for refractive surgery, contact lens fitting and corneal disease management.
a quantitative measurement of corneal curvature. The process is performed using a unique camera/computer combination called a corneal topographer or keratoscope. Used to determine corneal slope and astigmatism for laser vision - refractive correction. Also used post-operatively to measure the results of laser vision - refractive treatment. The computer data can manipulated to show the efficacy of ablation and the quality of smoothness of the final refracted surface. See corneal topographer.
Computerized map of the corneal surface identifying surface irregularities such as astigmatism. It also provides a quantitative measure on corneal curvature.
Mapping of the surface details of the cornea with a unique camera/computer combination. The corneal topographical map is a color display of the surface profile of the cornea. This information is used to follow the progress of a corneal disorder or help plan surgical procedures or fit a contact lens.

Mapping or examination of the cornea. The information gathered is useful to evaluate and correct many eye conditions. Go to Top
A corneal topographer shines light onto the surface of the eye, then measures the reflected light to create a map of the cornea's curvature as well as any irregularities. The map is used for evaluations related to refractive surgery, contact lens fitting and corneal disease management. It is especially useful for measuring astigmatism. The color map uses blue and green to represent flatter areas of the cornea, while red and orange represent steeper areas.

Mapping of the surface details of the cornea with a unique camera/computer combination. Used to determine corneal slope and astigmatism for PRK and LASIK refractive correction. The corneal topographical map is a color display of the surface profile of the cornea.
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topology is of critical importance in determining the quality of vision. The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses.
