enVista® Toric
Expanding Astigmatism Treatment Options
enVista® Toric extends the monofocal platform to patients with corneal astigmatism, including lower cylinder levels that may otherwise go untreated.5,6,7
Treat Astigmatism with More Precision5
More than 0.5 D of corneal astigmatism is common in cataract patients, making precise toric planning an important part of the surgical conversation.6,7
Most cataract patients have more than 0.5 diopters of corneal astigmatism, and correcting that astigmatism during cataract surgery is a common goal.6,7
Lowest available cylinder treatment*
1.25 D at IOL plane (<1 D at corneal plane)
Only toric platform that treats half-step cylinders*
(up to 3.5 D at IOL plane)
*Compared to other monofocial IOL toric platforms approved in the US.
enVista® Toric begins at 1.25 D at the IOL plane, corresponding to <1.0 D at the corneal plane, and offers half-step cylinder options through 3.5 D at the IOL plane.5
Correcting cataracts and astigmatism. BOTH at the same time.
Stability That Supports Toric Outcomes
Toric alignment and rotational stability are important to visual outcomes. The enVista® toric platform is designed to support stable positioning through the postoperative period.2*
The enVista toric platform delivers proven rotational stability through 180 days post-surgery2*
The enVista® platform is tailored to optimize toric outcomes
Toric alignment and rotational stability are vital for patient satisfaction and visual outcomes.
In the enVista® Toric MX60ET U.S. clinical study, 94.4% of eyes demonstrated ≤5° of rotation through 180 days.2*

3. What makes the enVista® optic aberration-free?
The enVista® optic is designed without added spherical aberration, allowing it to complement the cornea’s natural depth of focus rather than offset it with negative spherical aberration.4
4. What is the benefit of an aberration-free monofocal IOL design?
An aberration-free optic is intended to preserve the cornea’s natural depth of focus and support visual quality across a range of corneal profiles.4
5. Is the enVista® IOL glistening-free?
Yes. The enVista® platform uses a glistening-free hydrophobic acrylic material.1,4
6. What is TruSight® Optic?
TruSight® Optic refers to the enVista® glistening-free hydrophobic acrylic material, which demonstrated improved scratch resistance and 25 times the hardness of traditional hydrophobic acrylic IOLs in a nanoindentation study.1*
7. What is StableFlex® Technology?
StableFlex® Technology is designed to support efficient lens unfolding and optic recovery after implantation.²
8. What is SureEdge® Design?
SureEdge® Design is the enVista® platform’s sharp 360° square posterior edge, designed to help defend against posterior capsular opacification.²˒³
9. How does enVista® address posterior capsular opacification?
The enVista® platform incorporates a sharp 360° square posterior edge as part of the SureEdge® Design, which is intended to help reduce posterior capsular opacification.²˒³
10. Which cataract patients may be appropriate for enVista®?
enVista® may be considered for adult cataract patients who need monofocal correction after removal of the cataractous lens. Patient selection should account for ocular health, refractive goals, and the surgeon’s clinical judgment.²
11. Which patients may be appropriate for enVista® Toric?
enVista® Toric may be considered for adult cataract patients with corneal astigmatism who are candidates for toric IOL correction.5
12. How much astigmatism can enVista® Toric treat?
enVista® Toric begins at 1.25 D at the IOL plane, corresponding to less than 1.0 D at the corneal plane, and is available through 5.75 D at the IOL plane.5
13. Does enVista® Toric offer low-cylinder correction?
Yes. enVista® Toric offers a 1.25 D cylinder at the IOL plane, corresponding to less than 1.0 D at the corneal plane.5
14. Does enVista® Toric offer half-step cylinder powers?
Yes. The enVista® toric platform offers half-step cylinder options through 3.5 D at the IOL plane.5
15. Why can lower levels of corneal astigmatism matter in cataract surgery?
More than 0.5 D of corneal astigmatism is common among cataract patients, and residual astigmatism can affect visual performance after surgery.6,7,11
16. How stable is the enVista® Toric IOL after implantation?
In the enVista® Toric MX60ET U.S. clinical study, 94.4% of eyes demonstrated 5° or less of rotation through 180 days after surgery.2*
17. Why is rotational stability important in a toric IOL?
Toric alignment is important because rotation away from the intended axis can reduce astigmatic correction and contribute to residual postoperative cylinder.5
18. What design features support enVista® Toric stability?
The enVista® Toric platform uses modified C-loop fenestrated haptics and a lens design intended to support stable positioning in the capsular bag.2,5
19. What is the capsular bag contact of the enVista® Toric platform?
The enVista® Toric platform provides 110° of capsular bag contact as part of its lens design.*
20. What power ranges are available for enVista® and enVista® Toric?
enVista® monofocal is available from 0 D to +34.0 D, depending on increment range. enVista® Toric is available from +6.0 D to +30.0 D in 0.5 D increments.⁵
21. What are the key enVista® IOL dimensions?
The enVista® and enVista® Toric IOLs have a 6.0 mm optic and a 12.5 mm overall diameter, with modified C-loop fenestrated haptics.2,5
22. What material is used in the enVista®IOL?
enVista® is made from glistening-free hydrophobic acrylic material with a refractive index of 1.53 at 35°C and UV-absorbing properties.1,2,4
23. What delivery systems are available for enVista® and enVista® Toric?
Both enVista® and enVista® Toric are compatible with the BLIS® injector system and the INJ100 injector system for 2.4 mm incision delivery.2,5
24. What is the enVista® Toric Calculator?
The enVista® Toric Calculator is a planning tool powered by the Emmetropia Verifying Optical, or EVO, formula to support spherical-equivalent prediction and provide data for low-astigmatism cases.1
25. How should surgeons compare enVista® with other monofocal and toric IOLs?
IOL selection should consider optic design, material, rotational stability, cylinder range, handling, patient anatomy, refractive goals, and available clinical evidence. enVista® combines aberration-free optics, glistening-free hydrophobic acrylic material, and a toric platform with low-cylinder and half-step options.1,4,5
