Corneal Topographer is an ophthalmic diagnostic device used to map and analyze the surface curvature and shape of the cornea. It provides detailed topographic images that help eye-care professionals evaluate corneal irregularities, astigmatism, keratoconus, and other corneal conditions. Corneal topographers are also widely used for contact lens fitting, refractive surgery assessment, and pre- and post-operative evaluation, supporting accurate diagnosis and personalized treatment planning.
