Keratoconus is a corneal degeneration that leads to progressive corneal thinning, corneal warping, and a resultant irregular astigmatism. In 2026, the goal in keratoconus management should be interventional, preventing keratometric progression, ultimately saving visual acuity and quality. This lecture aims to review tips and diagnostic tools for earlier diagnosis, discuss the staple of halting disease progression with corneal crosslinking, and finally review optical and surgical tools for visual rehabilitation.
