Purpose
To investigate clinical outcomes obtained in a real-world setting from subjects implanted with RayOne EMV (RAO200E, Rayner) intraocular lenses (IOL).
Setting
Hospital Universitario La Zarzuela, Madrid
Methods
Preoperatively, manifest refraction and monocular corrected distance visual acuity (CDVA) were obtained. Postoperatively, manifest refraction, monocular and binocular uncorrected distance (UDVA) and uncorrected intermediate visual acuity (UIVA) as well as uncorrected near visual acuity (UNVA) was measured. In addition, defocus curve and contrast sensitivity were assessed. To receive subjective feedback, patients were asked about their overall visual impression, experience of dysphotopsia and spectacle independence for distance, intermediate and near distances.
Results
Interim data of 147 eyes from 91 patients were included. Postoperatively, MRSE was -0.15±0.27 D. Mean monocular UDVA is 0.03±0.06 logMAR and binocular UDVA was -0.02±0.04 logMAR. Monocular UIVA and UNVA were 0.03±0.05 logMAR and 0.18±0.11 logMAR, respectively. The defocus curve shows a VA of 0.2 logMAR or better between +0.5 D and -3.0 D. Contrast sensitivity outcomes are similar to those of monofocal lenses. Out of the 147 eyes, dysphotopsia was reported in 7 eyes. For 100% of eyes the visual impression was reported to be satisfying or very satisfying. Spectacle independence was reported with 98.6% for distance and 93.1% for intermediate vision. On near vision 43.3% of the eyes were reported to never or occasionally need spectacles.
Conclusions
The RayOne EMV IOL showed a significant restoration of near, intermediate and distance visual acuities. The defocus curve demonstrated functional vision between 33 cm and infinity while providing contrast sensitivity outcomes similar to monofocal IOLs. Spectacle independence was very high for distance and intermediate vision but with almost 50% for near vision, the lens provides a useful near vision too. As confirmed by a low rate of photic side effects and a very high satisfaction rate, the lens provides good visual quality.
