First Visual Results With A New Non-Diffractive “Enhanced” Monofocal Iol In Blended Vision Mode And Evaluation Of Photopic Phenomena

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 non-dominant eye: -1.5D, 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 ability and whether photopic phenomena are perceived by the patients.

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

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 and asked for photopic phenomena.

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. No halo and glare were perceived by all patients.

The first clinical data show excellent results. Due to the lack of photopic phenomena, the investigated IOL implantation is a very interesting alternative to MIOL.
