Purpose

To report real-world experience with a new toric enhanced monofocal intraocular lens (IOL), the RayOne EMV Toric. The RayOne EMV optic uses controlled positive spherical aberration and is optimized for monovision.

Setting

Clinical setting, surgical centres and hospital departments

Methods

This observational multicentre case series includes data of 116 eyes of 70 patients implanted with a RayOne EMV Toric IOL. Postoperative data are available for 113 eyes at 1 (1M) and 79 at 3 months (3M). For some patients, a monovision approach applied. Refraction outcomes include manifest refraction reported in sphere, cylinder and manifest refraction spherical equivalent (MRSE) and the resulting prediction error (PE). Vision is reported by means of monocular and binocular corrected and uncorrected visual acuity (CDVA and UDVA) as well as uncorrected intermediate and near visual acuity (UIVA and UNVA). Surgeons’ observations and patient reported outcomes concerning satisfaction and spectacle use were gathered via simple questionnaires.

Results

After implantation of the tIOL with cylindric powers of 0.75 to 4.5D, the mean manifest cylinder of -1.32±0.91D (N=66 preoperatively) decreased to 0.29±0.44D at 1M (N=106), and 0.23±0.38D at 3M (N=79). Mean MRSEs of -0.42±0.54D (1M) and -0.34±0.48D (3M) correspond to mean PEs of -0.28±0.42D (1M) and -0.18±0.41D (3M). Binocular UDVA and CDVA outcomes are all ≤0.02logMAR, while UIVA is -0.04±0.16logMAR (1M) and -0.05±0.18logMAR (3M). At both follow-ups more than 84% have a UNVA of ≤0.30logMAR, less than 50% require glasses for near tasks, and at least 92% are satisfied or very satisfied with their vision. Surgeons observed postoperative IOL rotation with different techniques and report no rotation in 86% (1M) and 85% (3M) of eyes.

Conclusions

The real-world data for the RayOne EMV Toric show very promising outcomes. Postoperative cylindrical outcomes demonstrate high efficacy concerning the astigmatism correction and surgeons report very good rotational stability. Overall, refractive outcomes were stable for the follow-up time of up to 3 months. Visual acuity measurements show best outcomes binocularly and for intermediate distance. Mean and cumulative visual acuity outcomes indicate satisfying reading abilities for intermediate and near distances, proving the efficacy of the enhanced monofocal design of the IOL optimized for monovision. Those objective outcomes are supported by subjective patient reported data such as the high patient satisfaction.
