Patients who underwent routine bilateral implantation of the same EDOF IOL (DEN00V, PureSee, Johnson & Johnson, USA) were included in this study. Study examinations were performed minimum 4 weeks after surgery and included autorefraction, subjective refraction, assessment of monocular and binocular uncorrected and best-corrected distance (4m) visual acuity (UCDVA and BCDVA in logMAR), uncorrected and distance-corrected binocular intermediate (66 cm) visual acuity (UCIVA and DCIVA in logMAR), binocular best-corrected and uncorrected near visual acuity (BCNVA and UCNVA in logRAD) and defocus curve in logMAR. Furthermore, patient satisfaction and postoperative spectacle independence were assessed using a validated German questionnaire (Cataract and Lens Ophthalmic Questionnaire).

In total, 100 eyes of 50 patients will be included in this study. Preliminary data of 30 patients showed a mean spherical equivalent of -0.26 dpt on the right eye and -0.12 dpt on the left eye. Mean binocular UCDVA and BCDVA was -0.05 logMAR ± 0.07 logMAR and -0.09 ± 0.06 logMAR respectively. Mean UCIVA and DCIVA was 0.06 ± 0.08 logMAR and 0.09 ± 0.06 logMAR, while a mean UCNVA of 0.336 ± 0.14 logRAD and BCNVA of 0.389 ± 0.13 logRAD was reported. Nineteen patients (64%) achieved full or almost full spectacle independence, while only 17% reported constant dependence of reading glasses. Postoperative patient satisfaction was high, with 93% of patients very satisfied with the visual outcome.

The PureSee EDOF IOL provided good uncorrected and corrected distance visual acuity as well as enhanced intermediate visual acuity. Patients reported a high rate of postoperative satisfaction as well as substantial spectacle independence after surgery.
