Corneal topography is a diagnostic test that maps the curvature and shape of the cornea, the clear front surface of the eye. It is commonly used to evaluate patients for refractive surgery and to diagnose corneal conditions such as keratoconus. The test is quick, non-invasive, and does not require contact with the eye. Advanced imaging technology creates a detailed color-coded map showing variations in corneal shape and thickness. Corneal topography provides critical information for surgical planning, contact lens fitting, and monitoring corneal disease progression. It allows for highly personalized and precise treatment decisions. This diagnostic tool plays a key role in ensuring safety and accuracy for vision correction procedures.
