Functional Outcomes After Implantation Of An Edof Iol With A Refractive Technology And Monofocal-Like Dysphotopsia Profile

To evaluate the functional outcomes including visual performance and patient reported outcomes after implantation of the refractive Enhanced depth of focus (EDOF) intraocular lens (IOL) Tecnis PureSee DEN00V and TECNIS PureSee Toric II (JnJ, US).

This ongoing prospective study includes 50 eyes of 25 patients who underwent phacoemulsification with implantation of Tecnis PureSee DEN00V and Tecnis PureSee Toric II (JnJ, US). The mean age of the patients was 69 ± 11 years. Postoperative follow-up at 3 months included uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance corrected intermediate visual acuity (DCIVA) at 80 cm, and uncorrected (UNVA) and distance corrected near visual acuity (DCNVA) at 40 cm. Binocular best-corrected defocus curve analysis in the range +2 to -4 and halo and glare simulation were evaluated 3 months after surgery.

Mean binocular visual acuity in logMAR at 3 months follow-up was UDVA/ CDVA (-0.01/ -0.07), UIVA/ DCIVA (0.05/ 0.04) and UNVA/ CNVA (0.18/ 0.21). Results indicate that the Tecnis Puresee IOL performs comparable to standard monofocal IOLs with a low amount of photopic phenomena. 

Initial results showed good visual acuity and reduced photopic phenomena. In particular, patients reported little or no photopic phenomena in terms of halo and glare simulation. The IOL power calculation for the Tecnis PureSee IOL and the implantation behaviour are uncomplicated.
