Toric IOLs for Low Cylinder Astigmatism

An Opportunity to Do More for Your Patients

Refractive vision is built on correction of both defocus and astigmatism. Patients need functional visual acuity for driving at night and other ordinary activities. But low-level astigmatism can have a negative impact on functional vision.1 Visually significant blur starts at just 0.5 D cylinder. 2

Visual Conditions Are Rarely Optimal
Outside Your Clinic1

It’s easy to overlook low cylinder astigmatism in the clinic. After all, the lighting is great, charts are high contrast and glare is absent. But on the road at night, where functional visual acuity is essential to your patients, low cylinder astigmatism can have a significant impact.

Small amounts of astigmatism have been proven to have a big impact on visual acuity.

*Percentages of eyes with logMAR visual acuity (VA), logMAR functional visual acuity (FVA), and low contrast visual acuity (LCVA) of ≥0.0 (20/20) with additions of different values of against-the-rule (ATR) astigmatism. With-the-rule (WTR) results were the same or worse under all conditions. Functional visual acuity refers to a patient’s visual performance related to daily activities such as driving, reading and visual display-terminal work. Low-contrast visual acuity refers to visual performance related to tasks such as reading road signs and navigating at night.

You May See More Toric Candidates Than You Realize

Low cylinder patients are the largest population eligible for toric IOLs. When you start evaluating toric candidacy at 0.5 D cylinder,** you may increase your opportunity to deliver excellent, lasting visual acuity.

**Potential Astigmatism Management patients may have 0.75 D or higher total corneal astigmatism, including those with 0.5 D or higher ATR anterior cylinder, as well as patients with 1.25 D or higher WTR anterior cylinder.

Prevalence of Corneal Astigmatism Prior to Cataract Surgery3

52% of cataract patients are candidates for toric IOLs, including patients within 0.5 D–1.50 D of astigmatism.

How Do You Treat This Large Patient Population?

Even low levels of cylinder can make driving and watching TV a struggle for cataract patients.

Transportation, connectivity and entertainment are important to patients' happiness, and in the Refractive Outcomes Era, cataract surgery is evaluated by quality of vision and overall satisfaction. 4
