Abstract Details

Purpose:

To compare visual outcomes with 5 different intraocular lens (IOL) designs

Setting:

BMI Southend Hospital, Westcliff on Sea, UK

Methods:

185 participants having undergone bilateral phacoemulsifaction and IOL implantation with AT LISA 739M diffractive trifocal (n=50), Bi-Flex MY diffractive bifocal (n=43), Symfony EDoF (n=20), Mplus refractive bifocal (n=25) and Bi-Flex 677AB Monofocal (n=47), were followed up 3-6 months post-operatively. Distance, intermediate and near LogMAR acuities. Defocus profile and patient satisfaction/spectacle independence based on quality of vision questionnaires.

Results:

Repeated measures ANOVA F4,6 = 29.04, p<0.01 showed significant differences between the IOLs. However no differences between any of the IOLs for UDVA and CDVA. For DCIVA, there was similarity between AT LISA, Mplus and Symfony IOLs (DCIVA > 0.25LogMAR) , and better than Bi-Flex MY and Bi-Flex 677AB. For near vision, the Symfony and BiFlex 677AB IOL had significantly lower acuity (Symfony 0.31 ± 0.16, Bi-Flex 677AB 0.54 ± 0.17) than the others but the Symfony was still significantly better than the monofocal. Spectacle independence was greater in the AT LISA, Mplus and Bi-Flex MY groups.

Conclusions:

All lenses provide good distance acuity. The Symfony EDoF lens provides good DCIVA, however it doesn’t improve near vision to the same extent as the multifocal IOLs and as such spectacle independence post-operatively is much lower.
