Simplifying and understanding various topographic indices for keratoconus using Scheimpflug based topographers

Indian Journal of Ophthalmology, 2020
Keratoconus (KC) is a progressive ectatic corneal disorder. There are multiple topographic devices and their varied indices used for diagnosis, detecting progression, and deciding management.
