Morphology

keratectasia = ectasia (opaque) = kerat + ectasia

Formed from specialized medical combining forms ('kerat-' = cornea, 'ectasia' = dilation) that are unlikely to be understood by an average B1 learner from their parts.

Etymology

Keratectasia breaks into Greek parts: kerat- meaning 'horn' and used for the cornea, the clear front part of the eye, and -ectasia meaning 'stretching' or 'expanding'. So keratectasia is when the cornea 'stretches' or bulges outward, which explains why it can cause vision problems.
