Abstract Details

Purpose:

To evaluate and compare the visual outcomes achieved with 2 different diffractive trifocal intraocular lenses (IOL).

Setting:

University hospital Munich and SmileEyes Linz

Methods:

This retrospective study comprised 37 patients who underwent bilateral cataract surgery with implantation of a trifocal FineVision Pod F (PhysIOL S.A.) and 37 patients with insertion of a trifocal AT Lisa tri 839MP (Carl Zeiss AG) over a period of 17 months. Monocular and binocular uncorrected distance visual acuity (UDVA) was analyzed as well as uncorrected intermediate and near monocular visual acuity (UIVA, UNVA). Additionally, objective refraction was measured at 3 months postoperatively.

Results:

Binocular UDVA was -0.07 logMAR ±0.09 with FineVision and -0.08 logMAR ±0.08 with AT Lisa. UIVA was -0.01 logMAR ±0.07 and -0.02 logMAR ± 0.04; UNVA 0.06 logMAR ±0.07 and 0.05 logMAR±0.06. Spherical refraction was 0.42 D ±0.41 D with the FineVision and 0.13 D ±0.47 D with the AT Lisa and spherical equivalent (SE) 0.15 D ± 0.44D and -0.15D ±0.47D. Statistically significant differences were found between both IOL regarding the sphere and SE, with the AT Lisa resulting in a lower spherical refraction (P<0.01 respectively). Comparisons of all the other parameters among groups missed statistical significance P>0.7 respectively).

Conclusions:

Both diffractive trifocal IOL provide excellent distance, intermediate, and near visual outcomes as well as good refractive results in patients who underwent cataract surgery. Considering the lower spherical refraction and the myopic tendency after implantation of the AT Lisa, this lens should be favoured.
