The Impact Of Different Preoperative Parameters Upon Quality Of Vision Following Combined Implantation Of Complementary Multifocal Intraocular Lenses

To outline the impact of various preoperative parameters upon quality of vision (QoV), reading glasses requirement and overall satisfaction following bilateral implantation of complementary multifocal intraocular lenses (IOLs). This aims to provide surgeons with a clear resource to outline the impact of various preoperative parameters on outcomes, which aims to enable prediction of happy postoperative patients.

This retrospective review chart aims to include at least 50 patients implanted bilaterally with the Cristalens Artis Symbiose Mid and Plus complementary IOLs. Preoperatively, patients were categorized into 2 groups based upon either preoperative FTBUT (Group A: ≤6 seconds (secs), Group B: ≥ 8 secs), spherical aberration (SA) (Group C: ≤0.2um, Group D: >0.2um) or mesopic pupil size (Group E: ≤ 4.5mm, Group F: > 4.5mm). Quality of vision (QoV) and reading glasses requirement were compared between the groups, 3 months postoperatively.

So far this study includes 26 patients implanted with Artis symbiose IOLs bilaterally. The parameters assessed to date are preoperative FTBUT, SA and mesopic pupil size.

This new complementary multifocal IOL displayed excellent visual outcomes 3 months postoperatively. Binocular unaided distance, intermediate and near visual acuity was -0.04 ± 0.05 logMAR, 0 ± 0.08 logMAR and 0.11 ± 0.09 logMAR respectively. There was no significant difference between overall QoV scores and reading glasses requirement between the different preoperative FTBUT, preoperative SA, or preoperative mesopic pupil size groups.

Objective and subjective outcomes with this new IOL combination are high and a high level of complete spectacle independence was found. This combination appears to be highly tolerant of differing levels of preoperative FTBUT, SA and mesopic pupil size, with no negative impact found in this early analysis. Further data and analysis of various preoperative parameters will be presented at the conference.
