Loop memory of foldable lenses: IOL haptic material key to continued performance


Salt Lake City-An evaluation of four materials available for the manufacture of IOL haptics showed that polymethylmethac-rylate (PMMA), elastimide, and polyvi-nylidene fluoride (PVDF) had similar loop memory at a level that was significantly higher than that of polypropylene (PP) haptics. All lenses had a silicone optic.
