What it is
The thin, elastic, transparent basement membrane that wraps the whole lens; the zonular fibres attach to it around the equator.
Function
Shapes the lens during accommodation and anchors it to the zonules.
Size
4-23 micrometres thick, thickest near the equator in front.
Clinical note
In cataract surgery the front of the capsule is opened (capsulorhexis) and the empty bag holds the artificial lens implant.
