Abstract Details


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


C.M.A Centro di Microchirurgia Ambulatoriale, Via Donizetti 24, Monza (Milan)


39 eyes of 24 patients (mean age: 66.54 ± 9.41 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 2 years after surgery.


Preoperative distance Uncorrected Visual Acuity (UCVA) was 0.30 ± 0.29. At 2 years distance UCVA was 0.83 ± 0.12, monocular near vision was 20/22 and binocular near vision 20/17.33. 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.
