Key benefits of the AT ELANA 841P

Benefit overview

The best of ZEISS trifocal technology

Based on the optical design of the trifocal ZEISS AT LISA tri, a clinically proven IOL with over 170 peer-reviewed publications, AT ELANA® 841P from ZEISS is designed to provide both excellent clinical performance and exceptional patient satisfaction. It offers a distance-dominant light distribution with focus planes in the near, intermediate, and far range making it pupil independent and fully trifocal under both photopic and mesopic conditions.

Improving near-to-intermediate vision without compromising far vision

With improved diffractive structure, ZEISS AT ELANA 841P offers an increased light transmission efficiency which together with a higher allocation of light towards near vision can be expected to provide enhanced near-to-intermediate vision without compromising visual acuity at far distance.1

  • Spherical aberration-neutral design

    Spherical aberration-neutral IOLs are designed to be free from optical inaccuracies caused by light refraction. Resulting in less sensitivity to decentration, tilt and no interference with corneal higher-order aberrations (HOA).

  • Glistening-free2 material, stability and anti-PCO edge

    Excellent image quality and clarity through glistening-free material. The anti-PCO edge reduces posterior capsule opacification, decreasing post-surgical efforts and increasing patient satisfaction. The biomaterial and lens design of ZEISS AT ELANA 841P is based on ZEISS CT LUCIA 621P, a proven monofocal hydrophobic C-loop IOL. With a specially designed optic-haptic junction, the step-vaulted C-loop haptics allow for easy centering and maximizing direct capsular contact. This ensures a consistent and stable axial IOL position in the capsular bag.

Preferred hydrophobic C-loop platform, fully preloaded

ZEISS trifocal optics are now for the first time available on a hydrophobic C-loop platform. ZEISS AT ELANA 841P is always preloaded and offers an ideal solution for easy adoption in the OR.

  • ZEISS AT ELANA injection system, open IOL chamber, whole lens and blue plunger tip are being covered with a generous amount of ophthalmic viscoelastic.

    Easy-to-use fully preloaded injector

    The fully preloaded BLUESERT™ injector is easy to integrate into your surgical workflow, simple to use and designed for intuitive and reliable implantation.

  • It can be seen how the ZEISS AT ELANA injection system offers consistent and controlled injection.

    Consistent and controlled injection with smooth IOL unfolding behavior

    The heparin3 coating supports a smooth unfolding of the IOL.

Seamlessly integrated into your surgical workflow

Premium support for you and your patients

To complement our product, we offer clinical application support tools4 and resources including: IOL Power Calculation Service - an expert service performed by optometrists intended to support clinicians in selecting intraocular lenses by calculation of IOL power and predicted residual refraction even for extreme patient conditions. On MyZEISS Customer Portal and ZEISS Surgery Optimizer application you can find product related information and educational materials.

In addition, our patient communication tools5 serve you in attracting and educating patients on available IOL options, supporting clinicians to select the right IOL for each patient, and managing their expectations.

Peer perspective

Clinical & laboratory experience with ZEISS AT ELANA 841P

  • Prof. Dr. med. Gerd U. Auffarth, Germany
    Optical bench test results of ZEISS AT ELANA 841P
  • Dr. Peter Mojžiš, Czech Republic
    First clinical experience with ZEISS AT ELANA 841P

All my patients implanted with AT ELANA have been very satisfied with uncorrected visual acuity in all three distances. The fully preloaded injector is very smooth, and the AT ELANA fits through a 2.2mm incision.

The controlled unfolding of this new hydrophobic c-loop trifocal IOL and the stability in the capsular bag is excellent. I am very excited about this new addition to the ZEISS IOL portfolio.
