Toric IOLs are currently available with cylinder powers ranging from 1.5 D to 6.0 D. These lenses provide astigmatism correction of 0.75 D to 4.75 D at the corneal plane. The spherical power and cylinder power of a toric IOL are both indicated in the description of a toric IOL.

Can a toric lens correct astigmatism?

Are toric IOLs worth it?

Excellent Toric IOL Outcomes Research has shown that toric lenses produce excellent visual results after cataract surgery and can correct astigmatism more effectively than limbal relaxing incisions.

How long do toric lens implants last?

Once healed, which takes 1 or 2 days, this capsule holds the IOL securely for long-term visual acuity. The material from which the IOL is made is crystal clear and does not break down over time the way the natural lens of the eye does. This means that this new lens could last indefinitely, never requiring replacement.

When should toric IOL be repositioned?

Dr. Berdahl: Ideally an IOL should be re-rotated within the first 3 to 6 months after surgery. It can be done after 6 months, but be aware that capsular fibrosis can make this surgical maneuver more difficult.
