Abstract Details

Purpose:

To compare the visual outcomes and clinical performance of diffractive trifocal and extended depth of focus (EDOF) intraocular lenses (IOLs)

Setting:

Biruni University, Istanbul,Turkey

Methods:

Hundred and fifty eyes of 75 patients referred for phacoemulsification were included in this study. Group 1, including 40 patients with 80 eyes implanted with the AT LISA tri 839 MP (Carl Zeiss Meditec), and group 2, including 35 patients with 70 eyes implanted with the EDOF IOL (Tecnis Symfony; Abbott Medical Optics). Analysis of binocular uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), spherical equivalent (SE) refraction, defocus curves under photopic (85 cd/m2) conditions, and contrast sensitivity were performed during a 6-month follow-up period. A validated visual quality questionnaire was also completed.

Results:

There was no statistically significant difference between groups in UDVA (P=0.45), CDVA (0.62). The binocular UIVA and DCIVA were also comparable among the two groups (p=0.72 and 0.56, respectively). Binocular UNVA and DCNVA were statistically and significantly better fort he trifocal group than for the EDOF (p=0.009 and 0.001, respectively). There were no significant differences in contrast sensitivity between groups, dysphotopic phenomena was slighlty higher in group 1.

Conclusions:

Both IOLs provided excellent distance and intermediate visual outcomes. Trifocal IOL had an advantage over EDOF IOLs in near VA. Predictability of the refractive results and optical performance were excellent, and all patients achieved spectacle independence.
