Abstract Details

Purpose:

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

Setting:

C.M.A. Centro Microchirurgia Ambulatoriale - Monza - Milan - Italy

Methods:

65 eyes of 39 patients mean age: 64.08 ± 10.24 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.

Results:

Preoperative distance Uncorrected Visual Acuity (UCVA) was 0.30 ± 0.29. At 2 YEAR, distance UCVA was 0.91 ± 0.08, monocular near vision was 20/25 and binocular near vision 20/22.5. Monocular intermediate vision was 20/32, binocular intermediate vision 20/22.

Conclusions:

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