Trusight™ optic: glistening-free

The single-piece hydrophobic acrylic IOL glistening-free1,2

StableFlex™ technology: controlled unfolding3

For a smooth and controlled IOL delivery

Advanced Optics (AO) technology: aberration-free aspheric optic design

enVista®‘s Advanced Optics (AO) technology has been designed to not induce any positive or negative spherical aberration.

  • Neutral to the cornea
  • Less sensitive to decentration4
  • Preserves some degree of depth of field5
  • Aspheric anterior and posterior surfaces

AccuSet™ haptics: designed for predictability and stable centration1,2,6

  • Fenestrated haptics designed to prevent transference of stress from the haptic to the optic
  • Haptics designed to maximize the contact angle against the capsular bag

SureEdge™ design: continuous 360º posterior squareedge to prevent PCO*7
