Comparison of Conventional Keratometry and Total Keratometry in Normal Eyes [PDF]
BioMed Research International, 2020 Purpose. The relationship between conventional keratometry and total keratometry has not been fully investigated. This study was aimed at conventional keratometry measured with the automated keratometer and total keratometry with the corneal tomographer in ophthalmologically normal subjects. Methods.
