Measurement of
compression
force
In accordance with ISO 11979-3 appendix
A
The IOL, in an uncompressed state, is placed between 2 horizontal
HDPE
anvils.
The section is immersed in a solution kept at in situ conditions.
The anvils are then coaxially closed to the prescribed diameter*.
The movement of the optic body is not
restricted.
After stabilisation, the compression force exerted on the haptics
is measured to within a tolerance of
±0.01mN.
* Standard diameters : 10 mm and 11mm. On request, anvils can be
made in other
sizes.
