Abstract Details



Purpose:

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

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
