Early Experience With A New Premium Iol - Johnson & Johnson Zen00v Tecnis Puresee™

We wish to present our early experiences with a novel IOL desing for presbyopia correction, TECNIS PureSee. Our expirence is with 26 IOLs with a mean follow up of 3 months. The new IOL has no diffractive rings or easily visible zones while providing a good EDoF effect for patients.

This was retrospective study on patients who received the new ZEN00V IOL during routine cataract surgery. All cases were performed by experienced cataract surgeons NG and KG using a standard PHACO technique. Patients were evaluated on POD1, POW1, POM1 and POM3, evaluated and tracked values are UCVA, CDVA, UNVA; DCNVA, DCIVA, sine wave contrast sensitivity and defocus curves. Patient satisfaction was evaluated using cataract sf9 questionnaire.

All 26 implantations were uneventful and there was no difference in implantation versus pervious Tecnis IOLs. All patients achieved vision of 0.1 logMAR or better by POW1, as far as UNVA at POW1 was logMAR 0.3 at 33 cm. Average Add Power was +1.25D for DCNVA for logMAR 0.0 (range -0.1 to 0.1). Defocus curves showed a good range of vision from +0.5 to -2.0D, very similar to Tecnis Symfony (ZXR00/ZHR00) but without diffractive rings. No patients complained of positive dysphotopsia effects during the time of follow up. Sine wave contrast testing showed good contrast sensitivity especially compared to full range IOLs like Tecnis Synergy (ZFR00V). 

Although early with a short follow up and a smaller number of implanted IOLs this new non-diffractive EDoF IOL shows promise of good quality of vision and contrast sensitivity with a large usable range of vision for correction of presbyopia at the time of cataract surgery.
