Keratometry is done to assess:
Corneal sensation
Corneal endothelium
Corneal thickness
Curvature of cornea
Keratometry measures the curvature of cornea e.g. Placido's disc, Orb Scan, Pentacam Placido's 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.
