Overview
Progressive corneal ectasia producing thinning and irregular astigmatism, typically presenting from the teens to the third decade and strongly associated with eye rubbing and atopy. Early detection matters because corneal cross-linking can halt progression while vision is still good — the cost of a missed year is usually paid in lines of best-corrected acuity.
