Abstract Details

Purpose:

To evaluate the clinical and optical performance of the new AcrySof® Vivity® EDOF IOL.

Setting:

Single surgeon eye clinic, Haugesund, Norway

Methods:

This study was a non-interventional single arm study of visual outcomes after successful bilateral cataract surgery or refractive lens exchange surgery with uncomplicated IOL implantation. All subjects were assessed during a single visit between 1 and 3 months after their surgery. Clinical evaluations included measurement of visual acuity at distance, intermediate and near, manifest refraction, defocus curve and subjective measures of visual quality. Recruitment goal for the study is 25 subjects (50 eyes).

Results:

Data analysis for this abstract is preliminary and based on 20 eyes. We aimed at either binocular emmetropia or up to -0.5D of myopia in the non-dominant eye. The target Mean Spherical Equivalent (MSE) ) was -0.22D and we ended up with -0.25D. Uncorrected binocular defocus curved showed a peak of -0.03 (logMar) at -0,5D of defocus. A visual acuity of ≥ 0.2 (logMar) was observed between -2.5 and +1.5D of defocus indicating excellent optical performance. The initial rate of patient satisfaction was excellent with contrast sensitivity comparable to normal eyes and no spontaneous reports on disturbing dysphotopsias.

Conclusions:

This new AcrySof® Vivity® EDOF IOL is based on a novel design using wavefront shaping technology. Theoretically, this lens is designed to provide a broad range of optical performance without sacrifizing optical quality. The present study, though limited in size and postoperative follow-up, indicates that this design goal is achieved.
