Quality Of Vision After Implantation Of Non-Diffractive Monofocal Plus Rayone Emv Using Modest Monovision Of 1.0 D

To assess the quality of vision in more than 70 cataract patients implanted with the RayOne EMV or the Toric equivalent using a monovision approach targeting – 1.D in one eye. The selected patients have been previously identified as not suitable for diffractive and wavefront shaping IOL optics due to potential neurological insufficiencies.

To date 20 eyes of 10 patients were implanted with the Rayner RayOne EMV RAO200E or RayOne EMV Toric RAO210T IOLs after removal of cataracts. The dominant eyes were calculated to achieve emmetropia, the non-dominant eyes were targeted wit -1.0 D to achieve a modest monovision outcome. The real-world evidence included patients with concomitant mild ocular comorbidities, including dry AMD, Fuchs dystrophy and mild glaucoma. Preoperative and 1 month follow-up data were collected, including manifest refraction, monocular and binocular UDVA, UIVA, UNVA, as well as CDVA. Additionally, a surgeon questionnaire on intraoperative and postoperative experience and a patient questionnaire on satisfaction and spectacle independence were applied.

We found that 1.0 D monovision with Monofocal Plus IOL RayOne EMV from Rayner leads to good visual outcomes and is well tolerated by patients without complains about dysphotopsia. This approach gives patients sufficient and satisfying depth of focus, allowing them to have good uncorrected intermediate and reasonable near vision without the loss of distant vision.

Applying a modest monovision approach with a 1.0 Ddifference with the Monofocal Plus IOL RayOne EMV results in an increased depth of focus and uncompromised distance vision. This combination appears to be a safe and predictable solution for patients unsuitable for diffractive technologies.
