Purpose

To analyze the effect of PhysiOL® IsoPure123™ and AcrySof ® IQ Vivity™ extended range intraocular lens design on patients visual quality under photopic and mesopic illumination conditions.

Setting

The study was performed at the Hospital Universitario Sanitas la Moraleja in Madrid. All surgeries were performed by the same experienced surgeon (E.D.R). The study followed the principles of the Declaration of Helsinki.

Methods

Observational, prospective, cross-sectional study. Thirty-four patients operated on for cataract or lensectomy, with bilateral implantation of one of the two study intraocular lenses (IOLs) were included in the sample: 26 eyes with PhysiOL® IsoPure 123™ implant (BVI Medical/PhysIOL, Liége, Belgium) and 42 eyes with AcrySof® IQ Vivity™ (Alcon Laboratories, Inc, Fort Worth TX). After 30 days after surgery, an evaluation of photopic and mesopic, monocular and binocular visual acuity (VA) was performed for three distances: far (4 meters), intermediate (66 cm) and near (40 cm) with the ETDRS test. Finally, halo perception was measured with Halo V1.0 software. A p-value < 0.05 was considered a criterion of statistical significance.

Results

The analysis of visual acuity under photopic conditions showed no significant differences between the lenses for the distances evaluated. However, under mesopic conditions, statistically significant differences were observed between the two IOL models for binocular VA at intermediate distance without correction, with a p-value (0.001), the mean being (0.31 ± 0.09) and (0.51 ± 0.16) for the AcrySof ® IQ Vivity™ and PhysiOL® IsoPure 123™, respectively.

Conclusions

Both AcrySof® IQ Vivity™ and PhysiOL® IsoPure 123™ intraocular lens designs provide optimal VA for far and intermediate distances in both photopic and mesopic illumination conditions. The AcrySof ® IQ Vivity™ IOL provides better intermediate VA under mesopic conditions than the PhysiOL® IsoPure 123™ IOL, with this difference being clinically significant.
