Computerized corneal topography is a valuable diagnostic tool that primarily measures the curvature of the corneal surface. This technology produces a detailed map of the corneal shape, allowing practitioners to evaluate the regularity and quality of the corneal surface. By examining the topographic patterns, eye care professionals can assess conditions such as keratoconus, astigmatism, and other corneal irregularities that may influence visual acuity and surgical planning, especially for procedures like LASIK.

Understanding the curvature of the cornea is essential for ensuring accurate fitting of contact lenses and optimizing visual outcomes after refractive surgery. This focus on the surface curvature distinguishes it from other measurements, such as corneal thickness, crystalline lens position, or retinal blood flow, which are outside the purview of corneal topography. Thus, the capability of computerized corneal topography to measure corneal surface curvature is vital for diagnosing and managing various ocular conditions.
