Purpose

To evaluate distance, intermediate and near visual acuities and defocus curves of 4 IOLs with increased depth of focus: Eyhance (J&J), Isopure (BVI), RayOne EMV RAO200E (Rayner) and Impress (Hoya)

Setting

 a - Centre ophtalmologique Kléber, Lyon, France,  b - Clinique Juge, Marseille , France, c - Institut Ophtalmologique Sourdille Atlantique Nantes, France

Methods

This was a retrospective multicentre study. A total of 150 eyes of 75 patients with comparable preoperative characteristics (mean age, sex, axial length) and implanted with one of 4 IOLs with increased depth of focus were analysed. Monocular visual acuity was measured at distance, intermediate (60 cms) and near (33 cms) at 1 months after surgery. Defocus curve was measured monocularly for defocus between -3.0 D and 3.0 D. Comparison of visual performance between each group, but also with a control group of 50 eyes implanted with standard monofocal implants with aspheric profile was performed

Results

Uncorrected and best-corrected distance visual acuities did not show any significant difference between the 4 IOLs with slightly increased depth of focus, and also no significant difference with the control group. For intermediate visual acuity, there was a significant difference between each IOL and the control group. The defocus curves show a depth of field varying from 0.50D to 0.75D for all 4 IOLs

Conclusions

IOLs with different optical technologies can increase the depth of focus to a different extend. The examined IOLs provided an improvement of intermediate vision useful in everyday life, without clinically significant deterioration of the  distance vision. No side effects were reported during the study
