    Toric lenses: correcting astigmatism during lens surgery

    A toric intraocular lens corrects astigmatism at the same time as replacing your natural lens — combined with a monofocal, multifocal or EDoF design, depending on your visual needs.

    What is a toric lens?

    A toric intraocular lens has a different optical power in two perpendicular meridians, which lets it neutralise corneal astigmatism at the same time as short- or long-sightedness. Without this correction, astigmatism leaves the image blurred and stretched at every distance, even after a perfect lens exchange. The lens is calculated individually from corneal topography and biometry, and it is positioned along a precise axis inside the eye — a deviation of just a few degrees reduces the effect, so the alignment is planned digitally and verified during surgery. A toric version is available for monofocal, EDoF and multifocal lenses, so astigmatism never limits your choice of lens.

    Why choose a toric lens?

    Why choose a toric lens?

    Corrects astigmatism during the same procedure

    No separate treatment is needed for the cornea's irregular curvature.

    Combines with any focus design

    Available as toric monofocal, toric multifocal, or toric EDoF, depending on what you need.

    Precisely aligned to your eye

    Toric lenses are positioned at a specific axis, measured during your pre-operative exam, to correct your exact astigmatism.

    Available from ZEISS and Alcon

    Both manufacturers offer toric versions across their lens ranges.

    Who is it for?

    Toric lenses are recommended for patients undergoing refractive lens exchange (RLE) or cataract surgery who also have astigmatism — regardless of which focus design (monofocal, multifocal or EDoF) fits their other visual needs. Your degree of astigmatism and its axis are measured during your eye exam.

    This depends on how much astigmatism you have and how much it affects your vision. Your surgeon confirms during your eye exam whether a toric lens is needed, or whether a standard, non-toric lens is enough.

    Yes. Toric isn't a separate lens category — it's an added correction that combines with any focus design. That means you can get a toric monofocal, toric multifocal, or toric EDoF lens, depending on which focus range fits your needs.

    Toric lenses are placed at a specific angle, measured before your surgery to match your exact astigmatism.

    No — the surgery itself is exactly the same. The only difference is which lens is used, not how the procedure is performed.

    Astigmatism happens when the cornea — the clear front surface of the eye — isn't perfectly round, more like a rugby ball than a football. This causes light to focus unevenly, blurring or distorting vision at every distance, not just up close or far away.

    Yes, in some cases. Astigmatism can also be corrected with glasses, contact lenses, or laser techniques like SMILE PRO, FS‑LASIK, or SURFACE. A toric lens specifically corrects it during refractive lens exchange (RLE), ICL Visian or cataract surgery, when lens replacement is already happening for another reason.

    The axis — the precise angle at which the toric lens must sit to correct your astigmatism — is measured using corneal topography and other diagnostic scans before your surgery. This measurement determines exactly how the lens is positioned during the procedure.

    Toric lenses typically involve an additional cost compared to their non-toric equivalent, since they include a specialized correction for astigmatism. Your exact pricing is confirmed at the clinic, based on the lens design that fits your eyes.

    Toric lenses are available in a range of powers to correct varying degrees of astigmatism. Whether your specific level of astigmatism falls within the correctable range is confirmed during your eye exam.

    The toric correction principle is the same across all three, but the base lens differs: refractive lens exchange (RLE) and cataract surgery use a toric intraocular lens that replaces your natural lens, while ICL Visian uses a toric implantable lens placed in front of your natural lens without removing it.

    Both ZEISS and Alcon offer toric lens designs across their monofocal, multifocal and EDoF ranges, so a toric correction is available regardless of which focus design fits your visual needs.

    Toric intraocular lenses are designed to remain stable in position once healed, so the correction doesn't wear off over time the way it might with contact lenses.
