Purpose

To improve near vision, a non-diffractive enhanced monofocal IOL with positive spherical aberration can be implanted for good distance and intermediate vision in a blended vision model (target refraction in the non-dominant eye: -1.5D, in the dominant eye: 0.0D). The aim of this retrospective analysis was to investigate whether patients also benefit from this blended vision model in terms of postoperative defocus and reading abilities and whether photopic phenomena are perceived by the patients.

 

Setting

All surgeries were performed by one surgeon at Breyer-Kaymak-Klabe Eye Surgery and Premium Eyes in Duesseldorf, Germany, member of the International Vision Correction Research Center (IVCRC.net).

Methods

All eyes (n=20) were implanted with an enhanced monofocal IOL (RayONE EMV, Rayner). As part of our IOL quality management we retrospectively assessed binocular uncorrected and best-corrected defocus capacity three months postoperatively in consecutively operated patients. To obtain information about patient satisfaction, we used and evaluated the QIRC Questionnaire.

Results

After surgery all patients were able to see far (car driving), intermediate (PC/Laptop) and near (reading books/newspapers) without glasses. Reading small print was not possible without glasses.

Conclusions

The first clinical data show excellent results with a high spectacle independence. Due to the lack of photopic phenomena, it is a very interesting alternative to MIOL to implant the investigated IOL in a blended vision strategy. From our clinical results we consider the RayOne EMV more as an EDOF than an enhanced monofocal IOL. Compared to multifocal IOL (MIOL) the blended vision model shows less side effects and offers more retreatment options.
