Purpose

To evaluate the efficacy and safety of the Vivinex Gemetric and Vivinex Gemetric Plus IOLs (Hoya Surgical Optics) using the pairing approach (first eye treated with Gemetric and second eye with Gemetric Plus) in refractive lens exchange patients. The trifocal IOLs, distinguished by their different light distribution characteristics, are based on the hydrophobic Vivinex platform and are preloaded in the multiSert injector.

Setting

This prospective, interventional clinical study is conducted at the university Eye Clinic in Heidelberg, Germany.

Methods

In this study, 56 eyes of 28 patients will undergo bilateral refractive lens exchange with the implantation of Vivinex Gemetric/Gemetric Plus IOLs using the pairing approach. The postoperative follow-up at 3 months includes assessments of uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance corrected (DCIVA) visual acuity at 60 cm, and uncorrected (UNVA) and distance corrected (DCNVA) near visual acuity at 40 cm. Additionally, defocus curve testing with distance correction and contrast sensitivity testing under photopic and mesopic conditions will be conducted as part of the 3-month follow-up visit.

Results

Comprehensive findings from our 3-month follow-up, including data on UDVA/CDVA/UIVA/DCIVA/UNVA/DCNVA, defocus curve and contrast sensitivity will be presented at the ESCRS Congress in Barcelona.

Conclusions

So far, 7 patients have been recruited for the study. Recruitment is expected to be completed by the time of ESCRS. Based on findings from previous studies, we anticipate to achieve spectacle independence in the far, intermediate, and near distance.
