Astigmatism Correction Methods

Are You Ready to Offer Every Cataract Patient
the Highest Quality of Vision?

Managing cataract patients' astigmatism can mean a few things: glasses, LRIs, toric IOLs. Delivering great visual outcomes for your patients starts with your method of Astigmatism Management.

What is the optimal Astigmatism Management method for this astigmatic eye?

Spectacles

Opting for spectacles for astigmatic cataract patients means leaving corneal astigmatism unmanaged.

With glasses, only the center of the visual field achieves full astigmatism and spherical correction.

With glasses, only the center of the visual field achieves full astigmatic and spherical correction.

  • Peripheral vision remains poor.
  • Optimal correction moves with the patient’s head, not their moving line of sight.
 

Corneal Incisions

When you decide to manage a cataract patient's astigmatism at the time of surgery, you may consider limbal relaxing incisions. However, manual LRIs have been shown to produce suboptimal outcomes 1,2:

  • Degrade over time, resulting in increased refractive error1,2
  • Inferior astigmatic reduction1
  • Inferior post-op UCDVA and residual astigmatism1,2
  • Less predictability

Distance Spectacles Required After Cataract Surgery1

More LRI patients required glasses for distance vision 3 months after surgery than toric IOL patients.

Patient-reported need for distance spectacles 3 months postoperatively. Preoperative spectacle usage by group: toric IOL n=17 (85%); incision n=18 (80%). Postoperative spectacle usage by group: toric IOL n=3 (15%); incision n= 9 (45%). No statistical analysis was undertaken of patient-reported data.

Toric IOLs

Toric IOLs can deliver optimal quality of vision, both for patients with significant astigmatism (> 1.5 D) and for those with less (0.5 D–1.5 D).*,3-6

Toric IOLs can help you target precise outcomes.   Target precise outcomes7
Toric IOLs predictable, longer-lasting results than LRIs.   Predictable, longer-lasting results than LRIs1,2
Toric IOLs are designed to reduce spectacle dependence for distance vision.   Designed to increase spectacle independence for distance vision8
Toric IOLs with high stability can help secure optimal outcomes.   Established rotational and axial stability9-13

Toric IOLs like those designed by Alcon can help you deliver precise, optimized outcomes for patients with astigmatism as low as 0.5 D ATR.*,9-14 Learn more about how AcrySof® IQ Toric IOLs can help you manage astigmatism.

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