Abstract
Purpose :
To assess depth of focus and contrast sensitivity in patients implanted with Art40, Art70 and bilateral combination of Art40/70 (ArtIOLs, Voptica SL, Murcia, Spain). These lenses are a new type of non-diffractive EDOF IOL that have been designed to both, increase depth of focus and improve peripheral optics.
Methods :
Thirty cataract patients were implanted bilaterally with Art40 and Art70 IOLs. These lenses have an inverted meniscus shape and induced two different values of negative spherical aberration. The surgery was performed first in the dominant eye with Art40 and a few weeks later in the fellow eye with Art70. Monocular and binocular uncorrected visual acuities (UCVA) at 5 m, 66 cm and 40 cm, using trial lenses of -1,5 and -2,5 D and SLOAN charts under photopic lighting conditions were measured. Best corrected (BC) and Uncorrected (UC) contrast sensitivity (CS) at 3, 6, 12 and 18 cycles per degree (cpd) were also measured between 1-3 months after the last surgery.
Results :
The mean monocular (Art40 and Art70) UCVA (LogMAR) ± standard deviation (SD) were 0.01±0.02 and 0.05±0.06 for far; 0.11±0.11 and 0.02±0.03 for intermediate (66cm) and 0.33±0.16 and 0.12±0.10 for near (40cm). Binocular UCVA±SD with the combination Art40/70 for far, intermediate and near vision were 0.0±0.01, 0.01±0.03 and 0.09±0.09 LogMAR, respectively. Monocular UC contrast sensitivity values (Log units) for Art40 and Art70 were 2.05 and 2.02 at 3 cpd; 2.11 and 2.06 at 6 cpd; 1.67 and 1.62 at 12 cpd and 1.32 and 1.16 at 18 cpd, respectively. There were no statistically significant differences (p>0.05) for all spatial frequencies between BC and UC CS for both Art40 and Art70.
Conclusions :
The two models of ArtIOLs (Art40 and Art70) and the combination (Art40/70) significantly extended visual depth of focus providing a VA better than 0.2 LogMAR up to 66 cm for Art40 and up to 40 cm for Art70 and Art40/70, without the compromise of halos or disphotopsias. CS was comparable to monofocal IOLs.
