Refractive Optimisation Of Cataract Surgery With Te Monofocal Extended Depth Of Focus (Edof) Isopure

We tried to find the best refractive target and patient selection criteria to achieve spectacle independence after implantation of the monofocal EDOF IOL IsoPure 1.2.3®

This study took place at the Institut ophtalmologique de l'ouest.

Retrospective study on 278 eyes of 176 patients who underwent cataract surgery with an IsoPure ® intraocular isofocal lens implantation. Age, sex, preoperative refraction, optical biometry, keratometry, refractive target and postoperative near and distance visual acuity with and without correction result were collected up to one year.

253 eyes of 157 patients implanted with EDOF IOL IsoPure® were included in this analysis. The mean age of patients was 73 years ± 6.75. 63% of those patients were women. The mean post-operative spherical equivalent was -0.20 ± 0.49 dp. 30 days after surgery, the mean post operative uncorrected distance visual acuity was 0.2 -LogMar ± 0.17 in monocular and 0.12 -LogMar ± 0.13 in binocular. The mean post operative uncorrected near visual acuity was Parinaud 7 in monocular and Parinaud 6 in binocular . We will present the results of the multivariate analysis which determine physiological factors which could influence post operative results with this IOL.

Patient selection and optimization of refractive target prior to surgery combined with a micro monovision is a key to achieve spectacle independence.
