Abstract Details

Purpose:

To report on the performance of AT Lisa tri (Zeiss Meditec, Germany) trifocal lenses implanted bilaterally versus a combination of the Comfort +1.50 addition (Oculentis, Germany) multifocal IOL in one eye and the Mplus MF30 +3.00D addition (Oculentis, Germany) implanted in the contralateral eye.

Setting:

Optegra Yorkshire Eye hospital, Bradford, UK

Methods:

The study comprised 85 consecutive patients, 51 patients had the trifocal lens implanted bilaterally and 34 patients had the Comfort and Mplus MF30 combination implanted. Visual and refractive outcomes data were evaluated. The mean age of patients in the trifocal group was 60±8 years, in the Mplus ‘combination' group it was 62±7 years. Follow-up took place 57.1±36.1 days after surgery in the trifocal cohort and 78.2±36.1 days after surgery in the combination group.

Results:

Post-operatively, the mean binocular uncorrected distance visual acuity (UDVA) was -0.08±0.08 logMAR for the trifocal group and -0.06±0.05 logMAR for the combination group. Mean post-operative spherical equivalent refraction was 0.10±0.42 D for eyes implanted with trifocal and -0.20±0.46 D for eyes with an Mplus lens. Binocular UNVA data from the trifocal group showed that 97% of patients could read N6 or better and 68% of patients in the combination group could read N6 or better. In the trifocal group 97% of patients could read N12 or better binocular UIVA compared to 96% in the combination group.

Conclusions:

Both IOL approaches provided excellent binocular unaided visual acuity. For near vision, the bilateral trifocal implantation group outperformed the combination group but uncorrected binocular intermediate visual acuity outcomes were very similar in this study. Refractive predictability was excellent in both cohorts.
