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.
