Purpose

To report real-world experience with an enhanced monofocal intraocular lens (IOL), the RayOne EMV and its toric version by looking at single surgeon experience with sequential patients chosen with this lens. The RayOne EMV optic uses controlled positive spherical aberration to achieve a partial extension of range of depth of field.

Setting

Single centre and surgeon data collection at Midland Eye hospital in Solihull, Birmingham, UK. 

Methods

This retrospective single centre case series includes data of 58 eyes implanted with a RayOne EMV - both toric and non toric versions. Postoperative data are available at 6-8 weeks and further follow up data analysed. All eyes were targeted with emmetropia. Refraction outcomes include manifest refraction reported in sphere, cylinder and manifest refraction spherical equivalent (MRSE). Vision is reported by means of monocular corrected and uncorrected distance visual acuity (CDVA and UDVA at 6m) as well as uncorrected and distance corrected near visual acuity (UNVA and DCNVA at 40cm).

 

Results

At 6-8 weeks after implantation of the mean manifest subjective refraction, cylinder and MRSE (n = 41) were +0.10±0.32 D, -0.23±0.55 D and -0.02±0.04 D. Monocular UDVA and UNVA (n = 58) were +0.06±0.10 logMAR and 0.45±0.17 logMAR. Cumulatively UDVA of 0.2 logMAR or better was achieved by 94.83% and a UNVA of N8 or better was achieved by 68.52% of eyes.

Conclusions

The RayOne EMV non-toric and toric versions showed very good refractive outcomes as well as monofocal like distance visual acuity and functional near vision. Our results are comparable or slightly better compared to published data, e.g. Yeo et al. who reported a UNVA of 0.50±0.15 in the emmetropia group of his study comparing an emmetropia group with a mini-monovision group.
