Abstract Details


To present clinical data on residual refractive astigmatism and uncorrected visual acuity (UCVA) of the AmoTecnis MultifocalToric IOL (ZMT) after implantation in cataract surgery.


Departments of Ophthalmology, St Elisabeth Hospital Tilburg and Phacocentrum, Den Bosch. The Netherlands


The AmoTecnis MultifocalToric IOL contains a toric component on the anterior surface of the optic and a diffractive multifocal component on its posterior surface, but is otherwise structurally identical to the AmoTecnis one-piece lOL. An AmoTecnis MultifocalToric (ZMT150-300) IOL was implanted in 9 eyes of 6 patients. Three toric models were evaluated in cylinder powers of 1.5D (ZMT150 n=5), 2.25D (ZMT225 n=3), 3.0D (ZCT225 n=1), at the IOL plane. Outcome measures included residual refractive astigmatism and uncorrected visual acuity.


At 24-42 days postoperatively, the average refractive cylinder was -0.50 D±0.25, in ZMT150-300 groups combined. (average preoperative refractive cylinder: -1.71 D ±0.46). The average UCVA for the combined group was 0.92 D±0.09. Near vision was reached in similar magnitude for all patients.More information on IOL misalignment and incision-induced corneal cylinder as calculated using a double angle vector method will be presented.


lmplantation of the AmoTecnis Multifocal Toric IOL seems to be an effective and safe method for astigmatism correction in cataract patients, and requires only small rnodifications from a standard phaco-procedure.
