enVista Toric Intraocular Lens

202x218-envista-toric

While we’re treating your cataract, let’s also correct your astigmatism. The ideal combination of rotational stability and vision predictability.

Key Features & Benefits

  • Lock in rotational stability; 100% of patients had less than or equal to 5o rotation from 1 to 6 months1

    • 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 material glistenings detected at any time in a 2-year prospective study of 172 eyes1,2
  • Material 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 optic power, centre-to-edge; and better vision quality are delivered by Bausch + Lomb aspheric, aberration-free designed Advanced Optics4

Predictability

  • Rotational stability is a key to the function of any Toric IOL.
    • For each degree of rotation there is an approximate reduction of 3.3% of the astigmatic correcting potential6.
    • The effectiveness of correction is also a function of the rotational stability of the lens over time.
  • In a clinical evaluation, 100% of all 113 subjects had less than or equal to 5o of IOL rotation between Form 3 and 4 which exceeds the American National Standards Institute (ANSI) standard of 90% of subjects with less than or equal to 5o of rotation at 2 consecutive visits at least 3 months apart1.

Designed to minimise PCO

  • Step-vaulted haptics are designed to vault the optic posteriorly for direct contact with the capsular bag
  • Lens Epithelial Cell (LEC) migration is believed to be inhibited by 360° square barrier edge leading to reduced Posterior Capsular Opacification (PCO)5

Ease of use

  • Insertion through a 2.2-mm incision with a single-use injector
  • Positioning in the eye’s natural capsular bag and removal of viscoelastic are facilitated by controlled unfolding
