A Corneal Topography System is a diagnostic device used to create a detailed map of the cornea, the transparent front surface of the eye. It analyzes how light reflects from the corneal surface and converts the data into color-coded maps showing curvature and shape. This helps detect corneal disorders such as keratoconus, evaluate astigmatism, and plan refractive surgeries like LASIK. It is also useful for accurate contact lens fitting and monitoring corneal changes after surgery. The system typically includes optical sensors, imaging cameras, and computer software for analysis.
