Abstract Details

Purpose:

In a prospective, ongoing study functional and visual results of different refractive presbyopia correction intraocular lenses (PCIOL) and their combinations are evaluated, to find better solutions for individual patient care and postoperative outcome.

Setting:

Augentagesklinik Rheine.

Methods:

Patients were evaluated 3–6 months after uncomplicated implantation of either: (1) binocular Lentis-313 MF15 (Oculentis, Germany), (2) Lentis-313 MF15 in the distance dominant eye and Lentis-313 MF30 (Oculentis, Germany) in the fellow eye, (3) Lentis-313 MF20 (Oculentis, Germany) in the distance dominant eye and IC-8 (Acufocus, USA) in the fellow eye. All PCIOLs were targeted emmetropia, out of the IC-8, which we targeted -0.75 D. 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 0.07 D in group 1, -0.35 D in group 2 and -0.22 D in group 3. Binocular UDVA was 0.04, 0.2 and 0.1 logMAR respectively, with a binocular CDVA of -0.01, 0.1 and 0.0 logMAR. The binocular DCIVA in 80cm for group 1 and group 3 were 0.17 and 0.09 logMAR. 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. All 3 groups had 50% of their patients experience halo and glare as none to mild.

Conclusions:

All three options offer a high degree of spectacle independence from distance to intermediate. True near is mainly achieved in the MF20-MF30 group with slightly higher risk for dysphotopsia.
