STEP: An OCT-Based Keratoconus Classification System

The STEP system utilizes two parameters: the minimum overall stromal thickness (ST) and the standard deviation of epithelial thickness (EP). This approach provides a more detailed understanding of keratoconus progression, offering insights that may assist in clinical decisions, especially concerning corneal cross-linking (CXL) protocols.
