Early visual performance and subjective experience after bilateral implantation of a novel fully refractive extended depth of focus intraocular lens

Purpose
To outline the early postoperative visual performance and subjective quality of vision (QoV) after implantation of a new fully refractive extended depth of focus intraocular lens (IOL).

Patients and methods
The study enrolled 103 patients undergoing bilateral phacoemulsification with implantation of the Tecnis PureSee IOL (Johnson & Johnson). Refraction, uncorrected (UDVA) and best-corrected (CDVA) distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, defocus curves, electronic reading desk, QoV questionnaire and a halo and glare simulator were evaluated 3 months postoperatively.

Results
Mean binocular UDVA, UIVA and UNVA were -0.06 ± 0.07, 0.05 ± 0.08 and 0.20 ± 0.08 logMAR respectively. At 3 months, 83% were within ± 0.50D and 99% within ± 1.00D of the refractive aim. Minimal dysphotopsias and overall QoV scores of 8.68 ± 1.13 for the day and 8.08 ± 1.58 at night were reported. Of all patients, 98.1% reported better vision than preoperatively and 86.4% would recommend the procedure. Spectacle independence for distance, intermediate, and near was achieved in 100%, 94.2% and 66% of patients respectively.

Conclusion
The Tecnis PureSee IOL provided excellent distance and intermediate vision with good functional near vision. Patients reported high postoperative QoV and subjective functional vision, with minimal visual side effects.
