Abstract Details


To assess the performance of the new Tecnis 1-Piece multifocal toric intraocular lens (IOL) ZMT.


: University Eye Clinic, Paracelsus Medical University, Salzburg (Austria)


In a prospective, multicenter study the Tecnis Toric Multifocal 1-Piece IOL ZMT (AMO) is implanted in cataract patients (n= 35). After having signed informed consent, subjects are bilaterally implanted with either two ZMT IOLs or with a ZMT IOL in the first eye and a Tecnis Multifocal IOL ZMB00 in the second eye if this does not require a cylinder correction. Follow-up visits take place 1 day and 1 week after surgery for each eye and 1 month and 3 months after surgery for both eyes. Key evaluation criteria are uncorrected and best-corrected visual acuity for near and distance, defocus curves, refractive outcome, ocular/visual symptoms, rotational stability, spectacle independence and patient satisfaction.


A first interim analysis comprised 3 months follow up data of 13 patients. All eyes achieved an absolute difference of 1D or less vs. targeted refractive cylinder outcome, and 70% achieved difference of 0.5D or less. 85% of the subjects achieved 0.8 uncorrected binocular distance visual acuity or better and all subjects achieved 0.63 uncorrected binocular near visual acuity or better (decimal notation). Binocular depth-of-focus results for the ZMT lens series are similar to that achieved for the non-toric Tecnis Multifocal ZM900 IOL at six months postoperatively. Postoperative medical findings were typical of cataract surgery; no unusual medical findings were reported.


The combination of a diffractive posterior surface with an established 1-piece toric design in the new Tecnis toric multifocal IOL ZMT results in very good visual outcome in astigmatic patients with comparable percentage of cylinder reduction and safety results as the monofocal toric IOL ZCT. Depth of focus results are comparable to other Tecnis Multifocal IOLs.
