Title

Mixing & Matching Multifocal Lenses: Results of a European multicenter project

Purpose	To study visual performance, functional vision, independence of glasses and patient satisfaction in cataract and refractive patients undergoing bilateral multifocal lens (MIOL) implantation with a diffractive MIOL in one eye and a refractive MIOL in the fellow eye.
Methods	Patients eligible for bilateral MIOL implantation were recruited and received a ReZoom MIOL in their distance-dominant eye and a Tecnis ZM900 MIOL in the fellow eye. Follow-up visits were performed after 1-2 days, 30-60 days, and 120-180 days post surgery. Binocular uncorrected (UCDVA) and best-corrected (BCDVA) distance visual acuity and uncorrected intermediate (UCIVA) and near (UCNVA) were documented. Reading acuity and speed using Radner reading charts, photic phenomena, independence of glasses and patient satisfaction was recorded.
Results	Ten study centers recruited a total of 180 patients from which 90 patients passed the 120-180 days follow-up visit. Binocular uncorrected distance, intermediate and near visual acuity were 20/20, 20/38 and 20/25. Mean binocular BCDVA was 20/19. Reading acuity was 0.3 logRAD under mesopic and 0.1 logRad under photopic conditions and patients could read 172 words/minute under photopic and 164 words/min under mesopic conditions. Ninety-six percent of the patients needed no glasses at all after 120-180 days. Halos and glare were reported as mild and in few cases as moderate. All patients would select the same procedure again.
Conclusion	Mixing and matching MIOLs with different optical principles in suitable patients delivers an excellent visual outcome and a very high degree of spectacle independence.
