Abstract
Purpose :
To evaluate the clinical results obtained with the new PhysIOL Isopure 123: using an isofocal optical design to achieve functional intermediate vision
Methods :
An observational study of patients with a isofocal IOL (PhysIOL Isopure 123) implanted between December 2020 and October 2021. Visual outcomes were assessed 1 month postoperatively; uncorrected and best-corrected distance visual acuity using logMAR at 4 metres, uncorrected and corrected intermediate (70cm) and reading/near visual acuity using a Jaeger chart
Results :
Nineteen eyes of 18 patients were analysed. Mean preoperative distance visual acuity was 0.66 ± 0.71 logMAR. At the one-month post-operative follow-up visit, uncorrected distance visual acuity was 0.17 ± 0.17 logMAR and corrected distance visual acuity was 0.07 ± 0.12 logMAR. Two thirds (66%, n=12) of patients achieved uncorrected intermediate visual acuity (70cm) of N12 or better. Wearing their auto-refraction correction, sixty-six achieved N12 or better at 70cm and over half (53%) could read N10 or better at their comfortable near distance. There were no intra or post-operative complications of note. Mean post-operative spherical equivalent was -0.06 ± 0.04.
Conclusions :
The results demonstrated that the PhysIOL Isopure 123 is able to restore near, intermediate, and distance visual function.
