Title	Clinical performance of Tecnis multifocal acrylic lens ZMA00
Abstract Nr.	259

Purpose	To investigate best-corrected and uncorrected visual acuity, photic phenomena and independence of glasses with the acrylic version of the Tecnis multifocal lens. Optical bench data showed higher MTF-values compared to the silicone model.
Methods	In a prospective study 20 patients were operated on both eyes (40 eyes). Three month after surgery uncorrected and best-corrected visual acuity at far, intermediate and near distance ,C quant measurements ,as well as the incidence of halos and glare were recorded. Spectacle use and patient satisfaction were documented.
Results	Tecnis ZMA00 showed excellent results in uncorrected distance(0.91) and near visual acuity(0.95). Intermediate vision(0.6) was sufficient for computer work and to operate cell phones. Overall spectacle independence was 94%. Halos occurred in 25% of the patients but only 1 patient was bothered by photic phenomena. Patient satisfaction was rated 9.3 on a scale from 0 (very unhappy) to 10 (very happy).
Conclusion	Tecnis acrylic multifocal lens ZMA00 provides an at least similar visual performance as the silicone model. Spectacle independence is high and results in a high patient satisfaction.
