The surgical treatment or manipulation of the acute angle between the lens and the retina, or procedures dealing with visual acuity correction.
From Greek akis (needle or sharp point, also meaning acuteness) plus -ourgia (surgical work or operation), literally 'sharp surgery' or 'surgery of acuity.'
This rare surgical term shows how Greek actually built words for concepts that didn't exist when Greek was spoken—ancient roots adapted for modern medicine.
