Glistenings do exist. But not for enVista®

Quality of Vision

  •  Pre-hydrated (0.9 % saline solution) to equilibrium to prevent glistening formation
  • No glistenings detected at any time in a 2-year prospective study1,2
  • Abrasion resistance is increased due to improved surface durability 3

Designed to Minimise PCO

  • Step-vaulted haptics
  • 360° posterior square edge4

Advanced Ease of Use

  • Safe, simple, reliable insertion through a 2.2 mm incision
  • Easy positioning in the capsular bag by controlled unfolding
