Envista®

enVista® INTRAOCULAR LENS

ONE-PIECE HYDROPHOBIC ACRYLIC IOL

The design is distinctive. The outcomes are clear.

The eye is not a perfect optical system, due to its visual axis not passing through the center of the cornea, pupil, or lens. Even an IOL perfectly centered in the capsular bag may be significantly decentered with respect to the visual axis. The decentration of an IOL, with either positive or negative spherical aberration, can induce defocus, astigmatism, and coma.

The enVista® premium monofocal IOL has a unique set of features that help compensate for the eye’s natural imperfections and deliver outstanding visual outcomes to a wide range of patients.

Uniquely different. Clearly predictable

The advanced, aberration-free optic of the enVista® premium monofocal IOL is uniform power from center to edge across the principle meridian, meaning enVista is relatively less sensitive to the effects of common levels of decentration and tilt compared to IOLs designed with higher levels of asphericity.1

The best of both worlds–image quality and depth of field.

Now you don’t have to choose between image quality and depth of field. With its advanced aberration-free optic, enVista® provides a desirable balance between depth of field and image quality.2

Shown here is the relationship between Image Quality and Depth of Field provided by an average natural cornea along-side the Image Quality and Depth of Field provided by the aberration-free optic profile of enVista MX60.The Strehl ratio indicates the level of image quality in the presence of wavefront aberrations.

TruSight optic: Glistening-free and potential for resistance to scratches

  • enVista family of IOLs are the ONLY IOLs with Health Canada approved glistening-free labeling.3

StableFlex technology: Controlled and efficient unfolding

  • Provides improved material properties to enhance optic recovery4†

AccuSet haptics: Stable centration and performance

  • 300% more radial compression force than traditional hydrophobic acrylic5

SureEdge design: Continuous 360° posterior square edge

  • A continuous 360° posterior square edge construction has been shown to have the potential benefit of preventing PCO compared to round edge designs2
  • Low long-term PCO incidence: 2.2% capsulotomy rate at 3 years6
  • Cryolathed, micro-grooved peripheral edge to help reduce edge glare7
