Glistenings do Exist , but not for enVista. enVista is the first USFDA Approved single piece Hydrophobic IOL which is Glistening free. Glistenings are prevented and material stability enhanced by Hydrating the lens to equilibrium water content so that it will neither gain nor lose water, Packaging the lens in physiological saline to eliminate fluid exchange with the aqueous humor. Abrasion resistance is increased due to improved surface durability. Hydrophobic properties are maintained over time. Enhanced contrast sensitivity; uniform power, centre-to-edge; and better vision quality are delivered by Bausch + Lomb aspheric, aberration-free Advanced Optics.

Exceptional quality of vision

  • No glistenings detected at any time in a 2-year prospective study of 172 eyes1,2
  • Glistenings are prevented and material stability enhanced by:
    • Hydrating the lens to equilibrium water content so that it will neither gain nor lose water
    • Packaging the lens in physiological saline to eliminate fluid exchange with the aqueous humor2-5
  • Abrasion resistance is increased due to improved surface durability6
  • Hydrophobic properties are maintained over time3
  • Enhanced contrast sensitivity; uniform power, centre-to-edge; and better vision quality are delivered by Bausch + Lomb aspheric, aberration-free Advanced Optics7-9

Designed to minimise PCO

  • Step-vaulted haptics are designed to vault the optic posteriorly for direct contact with the capsular bag
  • LEC migration is believed to be inhibited by 360° square barrier edge10

Advanced ease of use

  • Safe, simple, reliable insertion through a 2.2-mm incision with a single-use injector
  • Precise positioning in the capsular bag and removal of viscoelastic are facilitated by controlled unfolding
