  FEATURES
  • Material (copolymer of hydrophilic monomers) – high level of biocompatibility
  • No spherical aberrations – minimized glare and unwanted images
  • Angulation 5° – reduced risk of secondary cataract development
  • Double square-edge – no posterior capsule opacifi cation caused by cellular migration
  • Cryo-lathing method of manufacturing – no glistening
  • Minimized capsular bag stretching – maximum comfort for the surgeon and patient
  • Excellent folding and unfolding ability – easy to inject
  • Special surface polishing – a lens does not stick to itself or instruments
