Purpose: The aim of this study is to quantify visual side effects in pseudophakic patients with different IOL Models in comparison to phakic patients with a cataractouse opacified lens.

Methods: In an ongoing prospective study, including patients who received either binocular implantation of trifocal IOLs Finevision (PhysIOL, Belgium) or AT LISA tri 839 (Carl Zeiss Meditech, Germany), an enhanced depth of focus IOL or a monofocal IOL, AT Lara 829, CT Asphina 409 or CT Asphina 509 (Carl Zeiss Meditech, Germany), or received a Mix & Match approach with the AT LARA in the distance dominant eye and the AT LISA tri in the near dominant eye, photic phenomena were evaluated with the use of the Halo & Glare Simulator (Carl Zeiss Meditech, Germany) and compared to a group of phakic patients with a cataractouse opacified lens. Additionally we performed subjective refraction measurements and visual acuity testings to look for correlations with photic phenomena.

Results: In the pseudophakic patients included so far, 43% reported halo and 71% reported glare (symmetric, no “angel wings”), halo and glare reported in all cases were described as undisturbing (AT LARA). Phakic patients with a cataractouse opacified natural lens show a significant amount of photic phenomena in all occurrences. Residual astigmatism also seems to play a role in the development of photic phenome. Monofocal and EDOF IOLs show a smaller amount of photic side effects compared to trifocal IOLs, while the Mix & Match approach seems to be closer to the EDOF and monofocals.

Conclusion: Photic side effects still seem to be a great problem in premium lens surgery. Later IOL Models show a comparable results in the Halo & Glare assessment like monofocal IOLs. Still the possibility of a mix & match approach offers a binocular approach for presbyopia correction with comparable photic phenomena.
