Purpose: To evaluate the long-term visual outcomes and refractive stability after surgery of two models of the new non-diffractive inverted meniscus intraocular lenses (IOLs): ArtIOLs®40 EDoF and ArtIOLs®70 Full Visual Range (ArtIOLs®, Voptica SL, Murcia, Spain). These lenses present a non-conventional inverted meniscus shape designed to mimic the optics of the crystalline lens enhancing peripheral visual quality in the periphery.
Methods: A total of 26 eyes implanted with ArtIOLs®70 and 75 eyes implanted with ArtIOLs®40 were evaluated. Postoperative spherical equivalent (SE) outcomes at 1–2 months (Visit 1) were compared to those at 9–31 months (Visit 2). Changes in SE were analyzed along with monocular uncorrected distance visual acuity (UCDVA) and monocular best-corrected distance visual acuity (BCDVA).
Results: Eyes implanted with ArtIOLs®70 showed an absolute difference in SE ± Standard Deviation (SD) of 0.20 ± 0.18 D between the two visits. The absolute differences in UCDVA and BCDVA were 0.06 ± 0.06 and 0.02 ± 0.04, respectively. Similarly, eyes implanted with ArtIOLs®40 showed an absolute SE±SD difference of 0.20 ± 0.19 D between visits, with UCDVA and BCDVA absolute differences of 0.06 ± 0.10 and 0.04 ± 0.06, respectively. No statistically significant differences were observed in any of the measurements (SE, UCDVA and BCDVA) between Visit 1 and 2 (p >0.05).
Conclusions: The inverted meniscus IOLs (ArtIOLs®40 and ArtIOLs®70) demonstrated a consistent refractive stability and maintained visual acuity over a long-term follow-up exceeding two years, with no significant changes observed in refractive outcomes or visual performance. This indicates that the specific and different shape of these lenses (with an inverted meniscus with the convex surface facing the retina and both aspheric surfaces) is not compromising long term stability.
