Abstract Details

Purpose:

To compare the visual outcomes of patients submitted to cataract surgery with bilateral implantation of one of two diffractive trifocal IOLs (Finevision Micro F, Physiol vs. AT LISA tri 839MP, Zeiss).

Setting:

Lusíadas Education and Research Center, Lisboa, Portugal. Cruz Vermelha Hospital, Lisboa, Portugal.

Methods:

This comparative case series included patients with cataract submitted to phacoemulsification with bilateral implantation of a Physiol Finevision Micro F IOL (Finevision group) or a Zeiss AT LISA tri 839MP IOL (AT LISA group). Over a 3-month follow-up period, the main outcome measures were monocular and binocular visual acuities measured without and with distance correction for far (UDVA, DCVA respectively), intermediate at 80 cm (UIVA, DCIVA) and near at 40 cm (UCNA, DCNVA) visual acuities, spherical equivalent (SE) refraction, defocus curves, glare and no glare contrast sensitivity (CSV-1000, VectorVision), the presence of photic phenomena and the use of spectacles.

Results:

The study included 60 eyes of 30 patients, 15 in each group. At 3 months, mean LogMAR UDVA was 0.03 ± 0.08 (Finevision) and 0.08 ± 0.12 (AT LISA) (P=.765), mean DCIVA was 0.04 ± 0.07 (Finevision) and 0.18 ± 0.18 (AT LISA) (P=.048) and mean DCNVA was 0.03 ± 0.06 (Finevision) and 0.11 ± 0.08 (AT LISA) (P=.032). Mean SE was -0.25 ± 0.30 (Finevison) and -0.02 ± 0.39 (AT LISA) (P=.087). There was no significant difference in defocus curves and contrast sensitivity. Photic phenomena were also similar between groups. All patients in both groups were spectacle independent.

Conclusions:

The implantation of both trifocal IOLs provided excellent distance, intermediate and near visual outcomes. Monocular DCIVA and DCNVA appear slightly better in the Finevision group. Both predictability of refractive results and optical performance were excellent, allowing all patients in this series to achieve complete spectacle independence.
