Purpose
To compare the rate of photic phenomena after bilateral implantation of either monofocal or presbyopia-correcting intraocular lenses (IOLs) using the Halo&Glare Simulator.
Setting
University Eye Clinic of Heidelberg, Germany
Methods
In this prospective, clinical study, we compared the rate of photic phenomena in 112 patients who underwent bilateral implantation of either monofocal (CT Asphina 409MP (Carl Zeiss Meditec); n=12) or multifocal IOLs (Panoptix TFNT00 (Alcon); n=42; FineVision HP POD F GF (BVI Medical); n=15; TECNIS Synergy ZFR00 (JnJ Vision); n=27; MiniWell Z7560CZ (SIFI); n=16). Clinical assessment included a slit lamp examination, subjective refraction, uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA). A computer-based software tool (Halo & Glare Simulator; Eyeland Design Network, Vreden, Germany) enabled the presentation of light phenomena, allowing patients to select from a range of predefined halo and glare patterns.
Results
The Synergy (size: 47.4±19.0; intensity: 50.1±18.1), FineVision (size: 46.5±23.0; intensity: 49.1±23.2) and PanOptix (size: 37.6±23.6; intensity: 42.6±22.5) groups demonstrated statistically significanty higher mean halo size and intensity values compared to the monofocal group (size: 7.2±13.8; intensity: 11.3±20.9) (all p<0.001). The lowest levels of halo size and intensity were observed in the Miniwell group (size: 22.2±19.6; intensity: 23.6±19.8), which showed no statistical difference compared to the monofocal group (p=0.153). In terms of glare size and intensity, there were no statistically significant differences in the mean values measured between the multifocal and monofocal groups.
Conclusions
Our analysis demonstrates that photic phenomena occur not only in presbyopia-correcting IOLs, but also in monofocal lenses. The measured mean halo and intensity values were lower in the monofocal and Miniwell lens groups compared to the diffractive presbyopia-correcting IOLs, highlighting the relevance of the optic design in perception of halos effects.
