Objective:

To objectively test the tolerance to astigmatism in patients implanted with the Tecnis Odyssey full visual range IOL.

Key Findings:
  • Patients maintained visual acuity within one line of best-corrected visual acuity with up to 1.0 D of WTR astigmatic defocus.
  • Over 90% of patients achieved 20/40 vision or better with up to 1.5 D of WTR astigmatism.
  • High patient satisfaction with 96.6% reporting no need for spectacles.
Interpretation:

The Tecnis Odyssey IOL demonstrates a high tolerance for residual astigmatism, providing excellent visual outcomes and minimal dysphotopsia.

Limitations:
  • Small sample size of 30 patients.
  • Study results may not generalize to patients with retinal pathology or severe dry eye.
Conclusion:

Preliminary data indicates that the Tecnis Odyssey IOL is effective in providing a full visual range with minimal visual disturbances, making it suitable for patients seeking spectacle independence.
