Comparison of Visual Outcomes of 2 Trifocal IOLs
Narrative Responses:
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).
Methods
This comparative case series included 60 eyes of 30 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) (15 patients in each group). Over a 3-month follow-up period, the main outcome measures were uncorrected and corrected monocular and binocular distance (UDVA, DCVA), 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), presence of dysphotopic phenomena and use of spectacles.
Results
At 3 months, mean UDVA was 0.03 ± 0.09 (Finevision) and 0.08 ± 0.15 (AT LISA) (P=.166), 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 ± 0.34 (Finevison) and -0.02 ± 0.43 (AT LISA) (P=.087). There was no significant difference in defocus curves and contrast sensitivity. Dysphotopic phenomena were also similar between groups (P=.521). All patients in both groups were spectacle independent.
Conclusion
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.
