    Toric IOL’s transitional conic design enhances tolerance to misalignment

    Device's pupil-independent behavior makes it an ideal option for patients with large pupils

    A new aberration-free, transitional conic toric IOL (Precizon, Ophtec) with good rotational stability and tolerance to misalignment is providing excellent visual and refractive outcomes for patients with pre-existing regular corneal astigmatism undergoing cataract surgery in Europe.

    “As little as 0.5 D of astigmatism can have a significant effect on the quality of vision after cataract surgery,” said José L Güell, MD. “Toric IOLs are an option for accurate correction of pre-existing astigmatism.”

    The results depend in part on precise IOL alignment because there is a 3.3% loss of cylindrical power correction for every degree that the IOL is off-axis.

    “Although newer techniques have improved the accuracy of intraoperative alignment to the intended meridian and newer toric IOLs demonstrate good rotational stability, it would also be advantageous if an IOL has a high tolerance of misalignment in case there is postoperative rotation,” explained Dr. Güell, associate professor, ophthalmology, Autonoma University; director of Cornea and Refractive Surgery, Instituto Microcirugía Ocular (IMO), Barcelona, Spain.

    “Because of its unique transitional conic toric surface, the Precizon IOL has a broader toric meridian that might be more tolerant to misalignment,” he added. “Clinical experience indicates that the refractive outcome is not significantly affected by minimal misalignment (< 5°).”
