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.
