enVista Intraocular Lens

202x218-envista

Glistenings do exist...but not for enVista. Long term clarity and quality of vision.1

Key Features & Benefits

  • Optimal quality of vision
    • No glistenings detected in a 2 year prospective study1,2
    • Enhanced contrast sensitivity due to Bausch + Lomb Advanced Optics4
  • Designed to reduce PCO due to 360° barrier edge5,6
  • Insertion through a 2.2mm incision

Optimal 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 water3

    • Packaging the lens in physiological saline to eliminate fluid exchange with the aqueous humor3

  • Enhanced contrast sensitivity; uniform power, centre-to-edge; and better vision quality are delivered by Bausch + Lomb aspheric, aberration-free Advanced Optics4



Designed to minimise Posterior Capsular Opacification (PCO)

  • PCO is a secondary clouding of the capsular bag that can occur following cataract surgery

  • Step-vaulted haptics are designed to vault the optic posteriorly for direct contact with the capsular bag

  • Lens Epithelial Cells (LEC) migration is believed to be inhibited by 360° square barrier edge6



Ease of use

  • Insertion through a 2.2-mm incision with a single-use injector

  • Positioning in the capsular bag and removal of viscoelastic are facilitated by controlled unfolding
