Violet Light-Filtering IOLs Improve Vision and Satisfaction in Mild Glaucoma
Overview
A study presented at the 2025 ASCRS meeting demonstrated that violet light-filtering Tecnis Symfony OptiBlue IOLs provide excellent visual outcomes and high patient satisfaction in mild glaucoma patients. The lenses offer good distance, intermediate, and near vision with minimal dependence on glasses and manageable nighttime dysphotopsias.
Background
Glaucoma patients undergoing cataract surgery often have concerns about contrast sensitivity and nighttime vision, which can be affected by intraocular lens (IOL) choice. Mild glaucoma patients increasingly seek spectacle independence similar to other cataract surgery patients. The violet light-filtering Tecnis Symfony OptiBlue IOL blocks short wavelengths responsible for light scatter, potentially improving contrast and reducing nighttime visual disturbances. This study evaluated the clinical outcomes of this lens in glaucoma suspects and patients with primary open-angle glaucoma.
Data Highlights
| Outcome | Result |
|---|---|
| Patients with 20/20 distance vision (monocular) | 80% |
| Patients with 20/30 or better vision (binocular, distance/intermediate/near) | 100% |
| Patients with 20/30 or better near vision | 60% |
| Patients reporting little or no glasses use | ~80% |
| Patients spectacle independent for distance | 95% |
| Patients spectacle independent for intermediate | 87% |
| Patients experiencing nighttime dysphotopsias | ~25% |
| Patients bothered by dysphotopsias | 20% of those affected |
Key Findings
- 80% of patients achieved 20/20 monocular distance vision post-implantation.
- All patients had 20/30 or better binocular vision at distance, intermediate, and near.
- Approximately 60% attained 20/30 or better near vision, reducing near glasses dependence.
- About 80% reported little to no need for glasses overall, with 95% spectacle independence for distance and 87% for intermediate vision tasks.
- Nighttime dysphotopsias occurred in about 25% of patients, but 80% of those were not bothered by these symptoms.
- The violet light-filtering EDOF lens effectively balances visual performance and patient satisfaction in mild glaucoma.
Clinical Implications
The Tecnis Symfony OptiBlue violet light-filtering IOL is a viable option for mild glaucoma patients seeking spectacle independence, offering good visual acuity across distances with minimal compromise from nighttime visual disturbances. Surgeons can consider this lens to address contrast sensitivity and nighttime aberrations common in glaucoma, expanding treatment options beyond traditional monofocal IOLs.
Conclusion
Violet light-filtering extended depth of focus IOLs provide promising visual outcomes and high patient satisfaction in mild glaucoma, supporting their use as an effective cataract surgery option in this population.
