TitleReal-World Visual Performance of a non-diffractive IOL with Extended Depth of Focus in Patients Implanted in Belgium
PurposeTo report real-world clinical outcomes of consecutive patients bilaterally implanted with Rayner RayOne EMV RAO200E. This IOL is a non-diffractive IOL using positive spherical aberrations to extend the depth of focus (EDoF).
MethodsThis prospective, non-randomized and open-label study was conducted at the Citadelle Hospital in Liège, Belgium. 49 eyes from 27 consecutive patients (16 women and 11 men, mean age: 74 years) were implanted with the Rayner RayOne EMV IOL (bilaterally 22 and unilaterally 5). After 3 months of follow-up, patients underwent refractive and visual acuity testing of photopic uncorrected (U), best-corrected (BC) or distance-corrected (DC) visual acuities (VAs) at distance (D, 6 m), at intermediate (I, 66 cm) and at near (N, 40 cm). Moreover, monocular defocus curve was measured.
ResultsAt baseline, mean subjective (SD) spherical, cylindrical, and spherical equivalent refractions were -0.17 (0.56), -0.57 (0.36) and -0.44 (0.51) D, respectively. The mean refractive difference between right and left eyes was 0.47 (0.40) D. Binocular mean logMAR (SD) UDVA was -0.06 (0.08); UIVA 0.18 (0.12); UNVA 0.38 (0.17); BCDVA -0.15 (0.04); DCIVA 0.31 (0.10); DCNVA 0.48 (0.11). All binocular visual acuity outcomes were significantly better than the corresponding monocular results (p<0.05). Between +1 to -1.2 D defocus, VA was found to be 0.2 logMAR or better and at -2 D defocus the mean VA was 0.46 logMAR, then slowly decreased to 0.77 (0.15) at -3 D defocus.
ConclusionThe results of this study suggest that the implantation of the new Rayner RayOne EMV IOL can provide excellent distance VA, good intermediate VA and functional VA, with a smooth and continuous defocus curve. A mini-monovision approach additionally supports the binocular VA functions.
