What is the main purpose of corneal topography?

The main purpose of corneal topography is to map the surface curvature of the cornea. This technique is essential in understanding the shape and contours of the corneal surface, which plays a crucial role in refractive surgery, contact lens fitting, and diagnosing various corneal conditions. By providing detailed information about the cornea's topography, this mapping helps eye care professionals identify irregularities, such as astigmatism or keratoconus, that could affect vision. The precise measurements obtained through corneal topography enable customized treatment plans and better outcomes for patients requiring corrective solutions for their vision.
