<prompt> Keratometry is done to assess:Corneal sensationCorneal endotheliumCorneal thicknessCurvature of cornea  <response>: Keratometry measures the curvature of cornea e.g. Placidos disc, Orb Scan, Pentacam Placidos Disc Aesthesiometer is used to measure corneal sensation Specular microscopy is used for corneal endothelium - count and morphology of endothelial cells Pachymeter is used for measuring corneal thickness.
