Glistenings do exist...but not for enVista

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

INDICATIONS: Indicated for primary implantation for the visual correction of aphakia in adult patients in whom the cataractous lens has been removed by an extracapsular cataract extraction method. The lens is intended for placement in the capsular bag.
WARNINGS: Physicians considering lens implantation under any of the following circumstances should weigh the potential risk/benefit ratio:
1. Recurrent severe anterior or posterior segment inflammation or uveitis.
2. Patients in whom the intraocular lens may affect the ability to observe, diagnose, or treat posterior segment diseases.
3. Surgical difficulties at the time of cataract extraction, which might increase the potential for complications (eg, persistent bleeding, significant iris damage, uncontrolled positive pressure, or significant vitreous prolapse or loss).
4. A distorted eye due to previous trauma or developmental defect in which appropriate support of the IOL is not possible.
5. Circumstances that would result in damage to the endothelium during implantation.
6. Suspected microbial infection.
7. Children under the age of 2 years are not suitable candidates for intraocular lenses.
8. Patients in whom neither the posterior capsule nor zonules are intact enough to provide support.
PRECAUTIONS: Do not attempt to resterilize the lens as this can produce undesirable side effects. Do not soak or rinse the intraocular lens with any solution other than sterile balanced salt solution or sterile normal saline. Do not store the lens at a temperature greater than 43°C (110°F). DO NOT FREEZE. Do not autoclave the intraocular lens. Do not reuse the lens. It is intended for permanent implantation. If explanted, sterility and proper function cannot be assured.
