Abstract Details

Purpose:

To report on the performance of AT-Lisa-tri (Zeiss Meditec, Jena, Germany) trifocal lenses and Mplus MF30 (Oculentis, Berlin, Germany) intraocular lenses implanted during cataract or lens replacement surgery.

Setting:

Optegra Yorkshire Eye Hospital, Bradford, UK

Methods:

Observational case series. The study comprised 50 consecutive patients, 25 patients had the AT-Lisa-tri lens implanted bilaterally and 25 patients had the Mplus MF30 lens implanted bilaterally. Visual and refractive outcomes as well as complications data were evaluated.

Results:

The mean age of patients in the AT-Lisa-tri group was 58 ± 8 years (range 44 to 74 years). In the Mplus MF30 group the mean age was 63 ± 6 years (range 53 to 76 years) (P=0.06). The follow-up visit took place 37 ± 41 days (range 7 to 196 days) after surgery in the AT-Lisa-tri cohort and 67 ± 53 days (range 14 to 274 days) after surgery in the M Plus MF30 group (P=0.005). Post-operatively, the mean monocular uncorrected distance visual acuity (UDVA) was 0.00 ± 0.11 LogMAR for the AT-Lisa-tri group and was 0.01 ± 0.10 LogMAR for the Mplus MF30 (P=0.61). Mean monocular corrected distance visual acuity (CDVA) was -0.081 ± 0.072 LogMAR for eyes receiving the AT-Lisa-tri IOL and -0.078 ± 0.067 LogMAR for the Mplus MF30 (P=0.48). Postoperative spherical equivalent refraction was within ±0.50 D in 84% of eyes implanted with AT-Lisa-tri and 88% with the Mplus MF30 (P=0.006). Uncorrected monocular near visual acuity (UNVA) data showed that 93% of eyes could read N6 or better with the AT-Lisa-tri and 77% of eyes could read N6 or better with the Mplus MF30 (P=0.03). No surgical or post-operative complications were reported in either group.

Conclusions:

Both IOL designs provided excellent monocular UDVA and CDVA and excellent combined UDVA and UNVA performance binocularly. For monocular UNVA, the AT-Lisa-tri performed somewhat better than the Mplus MF30 in this cohort, although the follow-up period was on average shorter in this group. Refractive predictability was better with the Mplus MF30 and the complication rate was zero with both lens types in this case series.
