Morphology
vitrectomy = vitreous (opaque) = vitre + ectomy
This is a specialized medical term built with a classical combining form plus '-ectomy', but the relation is not readily inferable for an average B1 learner.
Etymology
Vitrectomy starts with vitre- meaning 'glass' and ends with -ectomy meaning 'cutting out', the same ending you see in appendectomy. So a vitrectomy is an operation that removes the eye's clear, jelly-like 'glass' part to help restore vision.
