Corneal topography measurements should be performed

Explanation:
Corneal topography maps the cornea’s curvature and surface quality, which is essential before any refractive procedure. Having a baseline map helps determine if the cornea can safely undergo laser reshaping, identifies irregularities or ectasia risk, and guides the chosen treatment pattern to achieve accurate, predictable outcomes. That’s why the best answer is that topography should be performed prior to a refractive procedure, such as LASIK—this covers LASIK and other similar surgeries. It’s not limited to contact lens fitting or only relevant if cataracts are present.
