Dynamic fatigue durability test following standard ISO 11979-3 appendix G Dynamic fatigue durability tester, in accordance with the ISO 11979-3 annex 4.10 All loops shall be capable of withstanding, without breaking, 250 000 cycles of near-sinusoidal deformation of ± 0,25 mm around the compressed distance. The cycle frequency shall be adjusted according to the reactions of each implant. No loop tested shall break before the end of the test Procedure : 1 - Clamp the IOL's body on the mobile arm. 2 - Adjust the low point 3 - Compress the IOL to the theoric dimension by means of the micrometric screw. 4 - Adjust the frequency according to the reaction of the implant. 5 - Start the 250 000 compression cycles on the haptic 6 - Check periodically whether the IOL’s loop has not broken. For the hydrophilic materials, fill the cuvet with saline solution.
