Abstract Details

Purpose:

In a prospective study functional and visual results after binocular implantation of an EDoF IOL targeted emmetropia, binocular implantation of a trifocal IOL or a mix & match approach implanting the EDof IOL in the distance dominant eye and the trifocal IOL in the fellow eye were evaluated.

Setting:

Augentagesklinik Rheine, Germany.

Methods:

Patients were evaluated 3-6 month after uncomplicated implantation of either: (1) binocular EDoF IOL (AT LARA, Carl Zeiss Meditech, Germany), (2) binocular trifocal IOL (AT LISA tri, Carl Zeiss Meditech, Germany), (3) AT LARA in the distance dominant eye and AT LISA tri in the fellow eye. All IOLS were targeted emmetropia. We evaluated UDVA, CDVA, DCIVA in different distances, DCNVA, UNVA, all in logMAR, Salzburg reading desk to determine individual preferred intermediate and near distance, subjective dysphotopsia (halo and glare simulator) and patient satisfaction questionnaire.

Results:

Postoperative spherical equivalent was -0.23 D in group 1, 0.03 D  in group 2 and -0.16 D  in group 3. Binocular UDVA was -0.05, 0.04 and 0.02 logMAR respectively, with a binocular CDVA of -0.05, 0.0 and 0.0 logMAR. The binocular DCIVA in 80cm was 0.06 for group 1 and group 2 and -0.04 for group 3. Binocular UNVA was 0.33, -0.01 and 0.20, respectively.  Defocus curve analysis shows a comparable distance visual acuity for all 3 groups with the highest visual acuity at -2.5 D for group 2 and group 3.

Conclusions:

All three options offer a high degree of spectacle independence from distance to intermediate. Group 2 and 3 offer a high degree of spectacle independence in near while the mix & match group showed the flattest defocus curve from distance to near.
