innovationMADE BY ZEISS


Next generation EDoF IOL with the widest range of focus* in its category



AT LARA® 829MP is the new EDoF (Extended Depth of Focus) intraocular lens from ZEISS.

AT LARA EDoF IOL is designed to provide a high degree of spectacle independence and to induce less visual side effects compared to multifocal IOLs, enabling excellent vision over a wide range of distances.

This balance of increased spectacle independence and less visual phenomena is particularly attractive to patients with an active lifestyle, who wish to be spectacle-free for most of their daily activities but are more sensitive to halos and glare.

ZEISS AT LARA 829MP represents the next generation of EDoF IOLs providing an even wider range of focus, as well as superior optical performance and quality of vision.

    The perfect balance of increased spectacle independence
    and less visual side effects

    ZEISS AT LARA provides the widest range of focus among EDoF intraocular lenses.

    This leads to an increased spectacle independence, giving patients the chance to perform a wide range of activities without glasses, and thus to enjoy an active lifestyle. At the same time, the lens induces less visual side effects compared to multifocal IOLs providing more visual comfort, especially at night.

    Increased spectacle independence

    The new AT LARA 829MP from ZEISS is designed to provide the widest range of focus among EDof IOLs, for an expected higher spectacle independence, particularly at the intermediate distance.

    AT LARA application

    Pre-clinical results confirm widest range of focus*:

    The defocus curve of the new ZEISS AT LARA EDoF IOL was compared with that of Johnson & Johnson TECNIS Symfony in a pre-clinical study with 25 subjects. In the test setup, the IOLs were "virtually implanted" by placing them in the optical path of a dedicated device, permitting the conduct of standard vision tests in non-implanted subjects.


    The average defocus curve of ZEISS AT LARA shows higher visual acuity values than J&J TECNIS Symfony over a wider range of focus distances, suggesting more spectacle independence*.

    Less visual side effects

    ZEISS AT LARA optical design and patented Smooth Microphase (SMP) technology minimize light scattering and thus visual side effects. For more visual comfort, in particular at night.

    Smooth Microphase (SMP) technology

    In conventional diffractive designs the ideal surface contains steps with sharp angles (see left). Manufacturing technology will not allow to create these sharp angles (circles represent the movement of a lating tool). As a consequence a certain amount of light will be scattered in undefined directions. In contrast, the patented SMP introduces so-called phase zones as part of the optical design, leading to an ideal surface design with much shallower angles (see right) that can be manufactures more precisely, thus minimizing the amount of light scatter.

    Pre-clinical tests indicate less disturbance with ZEISS AT LARA than with J&J TECNIS Symfony**:
    In pre-clinical tests using the "virtual implantation" setup, 48 subjects compared four different IOLs in a typical night traffic situation in a random blinded manner: one monofocal IOL, two EDoF IOLs (ZEISS AT LARA and J&J TECNIS Symfony), and one trifocal IOL.


    The monofocal IOL was rated best by the test participants. ZEISS AT LARA was rated second, better than J&J TECNIS Symfony and the trifocal IOL.
