About the Medical Device
The AcrySof IQ Toric IOL is a medical device designed to correct astigmatism in cataract patients. It provides better postoperative uncorrected distance vision and greater spectacle independence compared to non-toric IOLs.
Importance of Astigmatism Correction
Astigmatism can significantly affect patients’ functional vision, and correcting it is crucial for better visual outcomes. Even mild astigmatism can compromise quality of vision, and toric IOLs can address not just 2D astigmatism but also 1D and below.
Toric IOL Benefits
Toric IOLs provide better postoperative uncorrected distance vision, greater spectacle independence, and lower postoperative astigmatism compared to non-toric IOLs and combinations of non-toric IOLs and relaxing incisions.
Measuring Astigmatism
Accurate measurement of astigmatism is critical, and devices such as the VERION system, Scheimpflug camera, and Pentacam can help measure axis and astigmatism.
Toric Calculator and SIA
The Barrett toric calculator is superior to ray-tracing software and other formulae, and accounting for posterior corneal astigmatism (PCA) is crucial for accurate calculations.
