Abstract

PURPOSE
To evaluate the clinical outcomes of patients with diffractive aspheric trifocal intraocular lens (AT.LISA tri839 MP(R) IOL, Carl Zeiss Meditec, Jena, Germany) implantation.
METHODS
Forty eyes of 53 patients received phacoemulsification and implantation of AT.LISA tri839 MP(R) IOL (Carl Zeiss Meditec). Uncorrected distant visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), refractive values, and defocus curve were evaluated at postoperative 1 month and 3 months. Optical quality was evaluated with the Optical Quality Analysis System (OQAS(R), Visiometrics, Castelldefels, Spain).
RESULTS
At the 3-month postoperative follow-up, the mean spherical equivalent was 0.01 +/- 0.31 D and the mean UDVA, UIVA and UNVA were 0.023 +/- 0.020, 0.155 +/- 0.091, and 0.139 +/- 0.069, respectively. The means of the objective scatter index, modulation transfer function cut-off value, Strehl ratio measured by OQAS(R) (Visiometrics) were 1.83 +/- 0.52, 33.58 +/- 14.27 cycle per degree and 0.18 +/- 0.11, respectively. Intermediate visual acuity did not fall sharply at defocus curve.
CONCLUSIONS
Implantation of the diffractive aspheric trifocal intraocular lens in patients with cataracts provided excellent distant, intermediate and near visual acuities with high visual quality.
