Postoperative Visual Outcomes, Spectacle Independence And Patient Satisfaction In Patients Implanted With A New Extended Depth Of Focus Intraocular Lens

With the increasing life expectancy and growing visual demands of modern society, achieving high-quality vision at multiple distances after cataract surgery has become a priority. Multifocal IOLs can reduce spectacle dependence but are frequently associated with photic disturbances such as halos and glare. Extended Depth of Focus (EDOF) IOLs have emerged as an alternative, offering an extended range of vision while minimizing optical side effects. This study aims to evaluate the postoperative visual outcomes, spectacle independence, patient satisfaction and the occurrence of photic phenomena in patients undergoing cataract surgery with the implantation of the TECNIS PureSee™ EDOF IOL.

A total of 25 patients (45 eyes) who underwent cataract surgery received the TECNIS PureSee™ EDOF IOL. Patients were followed postoperatively to assess uncorrected and corrected visual acuity at various distances, spectacle dependence, and the presence of photic phenomena. Spectacle independence was evaluated based on the need for additional correction for far, intermediate and near vision. Patient satisfaction was also assessed.

At the final follow-up, 100% of patients achieved spectacle independence for distance and intermediate visions, while 76% of those achieved complete spectacle independence. The remaining 24% required near vision correction only for Jagger No:1. No patients reported experiencing photic phenomena such as halos or glare. All patients were either satisfied or very satisfied with their vision.

The TECNIS PureSee™ EDOF IOL provided a high level of spectacle independence and patient satisfaction while maintaining excellent postoperative visual outcomes. Unlike multifocal IOLs, no patients experienced photic disturbances, making it a promising option for patients seeking a balance between extended depth of focus and visual comfort. Notably, it improved vision without the need for monovision, further enhancing its appeal for a broader patient population. As advancements in EDOF technology continue, further refinements in lens design may enhance near vision performance while maintaining visual quality, potentially making EDOF IOLs the preferred choice for a wider range of patients.
