1. An accommodating intraocular lens (AIOL) comprising:
a first component having—
a first optical portion having an optical axis;
a first haptic portion surrounding the first optical portion; and
a first annular wall connecting the first optical portion to the first haptic portion; and
a second component having—
a second annular wall connected to the first annular wall;
a second optical portion aligned with the first optical portion along the optical axis to form an optic chamber between the first optical portion and the second optical portion, the optic chamber having an adjustable optical power;
a second haptic portion connected to (i) the second optical portion via the second annular wall and (ii) the first haptic portion to form a haptic reservoir between the first haptic portion and the second haptic portion;
wherein—
one or both of the first annular wall and the second annular wall includes standoffs extending from the first or second annular walls;
spaces between the standoffs form passages through which fluid can flow between the haptic reservoir and the optic chamber; and
the optical power of the optic chamber is configured to increase when radial compressive force is applied to the first and/or second haptic portions.
