Abstract Details

Purpose:

The aim of the study was to compare two types of extended-depth-of-focus (EDOF) lenses (TECNIS Symfony and AT LARA 829MP) in patients who underwent cataract surgery in both eyes.

Setting:

European Eye Clinic Lexum, Prague, Czech Republic

Methods:

This cohort study evaluated the outcomes in 40 eyes (20 patients) after implantation of TECNIS Symfony (Johnson & Johnson) in 20 eyes and AT LARA 829MP (Carl Zeiss Meditec) in 20 eyes. Mean patient age was 67 years (46-76 years) and the mean follow-up period was 4 months. Postoperative measurements included monocular and binocular visual acuity (logMAR) - distance, intermediate at 60cm and near at 40cm. Subjective refraction, contrast sensitivity and defocus curve were also performed. Satisfaction, dysphotopsia and spectacle independence were assessed using one non-standardised and one standardised questionnaire.

Results:

The mean spherical equivalent 4 months postoperatively was -0.17±0.24 D (Symfony) and -0.12±0.37 D (AT LARA). Monocular UDVA was similar in both groups: 0.05±0.06 logMAR and 0.08±0.07 respectivelly. In Symfony group UIVA and DCIVA (0.23±0.12 and 0.23±0.09 logMAR) were better than in AT LARA group (0.27±0.11 and 0.26±0.08 logMAR). On the other hand UNVA and DCNVA in Symfony group (0.25±0.13 and 0.28±0.10 logMAR) were worse than in AT LARA group (0.21±0.12 and 0.25±0.08 logMAR). Contrast sensitivity was within the normal range in both groups. Defocus curve showed slightly better values of visual acuity in Symfony group.

Conclusions:

In this cohort study of 40 eyes after cataract surgery with implantation of extended-depth-of-focus lenses TECNIS Symfony and AT LARA 829MP demonstrated high levels of visual acuity, especially in distance and intermediate. Contrast sensitivity was not reduced and the amount of dysphotopsia was low. Outcomes were supported by high patient satisfaction with their postoperative vision even if they use glasses for reading sometimes.
