Clinical Outcomes And Patient Satisfaction After Bilateral Implantation Of New Rayone Emv Toric Intraocular Lenses

To investigate clinical outcomes obtained from subjects implanted bilaterally with Rayner RayOne EMV Toric Intraocular lenses (IOL).

Hospital San Rafael Servicio de Oftalmología, Madrid

Visual acuity and defocus curve are monitored with the EDTRS optotype at 4 meters and illumination of 85cd / m².

Contrast sensitivity using table CSV-1000HGT. At a distance of 2.5 meters (8 feet) with spatial frequencies of 3, 6, 12 and 18 cycles / degree.

This prospective data collection includes a total of 12 eyes from 7 patients who have been implanted with the Rayner RayOne EMV Toric IOL. Data were available preoperatively and 1 month postoperatively. The examinations included manifest refraction as well as monocular and binocular visual acuity data on uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA). Corrected visual acuity assessment was performed monocularly. In addition, binocular defocus curve and contrast sensitivity outcomes were obtained. To assess subjective outcomes, patients were asked about photic phenomena, spectacle dependence and general satisfaction.

The manifest cylinder significantly reduced from 1.19±0.56 D to 0.48±0.29 D (p=0.005) with 83% showing a cylinder ≤0.5 D. Mean monocular and binocular UDVA were 0.02±0.02 and 0.01±0.02 logMAR, respectively. CDVA was 0.02±0.02 logMAR. Monocular and binocular UIVA were 0.20±0.06 and 0.18±0.05 logMAR, respectively. The according UNVA outcomes were 0.37±0.10 and 0.31±0.10 logMAR, respectively. The defocus range (≤0.2 logMAR) is between -1.5 D and +0.5 D and contrast sensitivity outcomes are within the norm values of this age group. All IOLs were stable and centered with no rotation observed. No patient reported dysphotopsia and 100% were satisfied or very satisfied with their vision. 4 patients required glasses for near tasks.

The clinical results of 7 patients (12 eyes) implanted with the RayOne EMV Toric IOL show a simultaneous reduction of refractive cylinder and restoration of visual acuity over a broad distance range. High visual quality is confirmed by contrast sensitivity outcomes close to outcomes achieved with monofocal lenses and no patient reporting about halo or glare. In our opinion this IOL is a good choice for patients with pre-existing corneal astigmatism requiring good visual acuity for far and intermediate distances without sacrificing visual quality. As this is on ongoing data collection, latest outcomes will be presented with more eyes being implanted.
