To evaluate visual and optical performances of cataract eyes after phacoemulsification and trifocal Intraocular Lens (IOL) (AT LISA tri 839MP, Carl Zeiss Meditec) implantation.

Sixty-three eyes of 38 patients mean age: 63.92 ± 10.37 years underwent uncomplicated phacoemulsification and trifocal IOL (AT LISA tri839MP, Carl Zeiss Meditec) implantation. Preloaded IOL was implanted using a BLUEMIXS 180 injector. Postoperatively, the following visual and refractive parameters were measured: distance (5m) near (30cm) and intermediate (70 cm) visual acuity, corneal topography and aberrometry, contrast sensitivity and defocus curve. Regular follow-up examinations were performed up to 2 years after surgery.

Preoperative distance Uncorrected Visual Acuity (UCVA) was 0.30 ± 0.29. At 2 YEAR, distance UCVA was 0.95 ± 0.05, monocular near vision was 20/22 and binocular near vision 20/22.5. Monocular intermediate vision was 20/30.83, binocular intermediate vision 20/22.

AT LISA tri 839MP provided satisfactory distance and near as well as intermediate visual acuity. This lens also improved quality of vision through remarkable diffraction efficiency while maintaining contrast sensitivity.
