Purpose
Precizon Presbyopic® is a hybrid, acrylic intraocular lens with a continuous transitional focus, designed for the correction of presbyopia. Our purpose was to evaluate the refractive outcomes after Precizon Presbyopic® intraocular lens implantation
Setting
Refractive Surgery Unit, Ophthalmology Department, Centro Hospitalar Universitário do Porto, Portugal
Methods
Retrospective analysis of 28 eyes of 14 patients submitted to Precizon Presbyopic® implantation between August 2020 and January 2022 in Centro Hospitalar Universitário do Porto. Distance best corrected visual acuity (DBCVA) was evaluated in the logMAR scale. Near visual acuity was evaluated with the Jaeger Chart. Distance monocular visual acuity, binocular near visual acuity and spherical equivalent were evaluated before and after the surgical procedure. Presence of disphotopic phenomena was also recorded. All patients were asked if they were satisfied with the surgical outcome.
Results
Mean age was 59.4±6.3 years old and 80.0% were female. Mean spherical equivalent changed from -3.16±5.98 D [-16.5 to 3.5 D] to -0.11±0.26 D [-1.0 to 0.0]. In 60% of eyes a toric lens was implanted. Monocular DBCVA changed from 0.18±0.11 logMAR to 0.01±0.07 logMAR. Before surgery, 6 patients (42.9%) had binocular near visual acuity of J1, 7 (50.0%) of J2 and 1 (7.1%) of J3, all cases requiring correction (mean 2.62±2.32 D). After surgery, 6 patients (42.9%) had uncorrected binocular near visual acuity of J1, 3 (21.4%) of J1.5, 4 (28.6%) of J2 and 1 (7.1%) of J3. One patient complained of glare. No patient required distance glasses, and only one required near correction. All patients declared to be satisfied with the surgical outcome.
Conclusions
Precizon Presbyopic® lenses, besides giving good distance and intermediate vision, seem to also provide good functional near vision, allowing most patients to obtain glass independence. Only one patient complained of disphotopic phenomena, and all patients were satisfied with the surgical outcome.
