Purpose
To evaluate the functional outcomes of first series of patients in Switzerland after implantation of the new refractive EDOF lens Tecnis PureSee IOL DEN00V (JnJ, US)
Setting
Pallas Eye Clinic, Olten, Switzerland
Methods
This ongoing prospective study includes 20 eyes of 12 patients who underwent phacoemulsification with implantation of the Tecnis PureSee IOL DEN00V (JnJ, US). The mean age of the patients was 67±7 years. In this study we measured subjective refraction, corrected and uncorrected visual acuity, monocular and binocular [logMar] for distance, intermediate and near vision, and binocular best-corrected defocus curve analysis in the range of +2 to -4, evaluated 1 week, 4 weeks and 3 months after surgery. We also analysed patient satisfaction as well as photic phenomena using a halo and glare simulator.
Results
Mean binocular visual acuity in logMAR at 1 week after surgery was UDVA/ CDVA (0.1/0.0), UIVA/ CIVA (0.1/0.1) and UNVA/ CNVA (0.3/ 0.3) and 4 weeks after surgery was UDVA/ CDVA (0.0/0.0), UIVA/ CIVA (0.1/0.1) and UNVA/ CNVA (0.3/ 0.3). The binocular distance-corrected defocus curve at 4 weeks showed a continuous visual acuity of 0.20 logMAR or better in the range of +1.00 to -1.75 diopters and a continuous visual acuity of 0.10 logMAR or better in the range of +0.75 to -1.50 diopters of defocus curve.
Conclusions
The results of this first series showed good visual acuity and an increased range of focus of ~2.75D. Patients reported little or no photic phenomena such as halo and glare. IOL power calculation for the Tecnis PureSee IOL delivered predictable results and implantation behaviour was uncomplicated. Further evaluation of visual acuity and defocus curves at 3 months postoperatively is ongoing.
