| description | Kjell Gunnar Gundersen,1 Rick Potvin2 1IFocus Øyeklinikk AS, Haugesund, Norway; 2Science in Vision, Akron, NY, USACorrespondence: Kjell Gunnar Gundersen Email kg@ifocus.noPurpose: To evaluate the rotational stability, visual acuity and refractive error after sulcus implantation of a secondary toric IOL.Setting: One clinical practice in Haugesund, Norway.Design: Non-interventional single-arm diagnostic study.Methods: Eligible subjects who had previous successful primary cataract or refractive lens exchange surgery in one or both eyes and the AddOn® secondary toric IOL implanted in the sulcus were evaluated at a single postoperative diagnostic visit to measure visual outcomes. Subjects with surgical complications (either primary or secondary) or pathology that would affect best-corrected visual acuity (eg, amblyopia) were excluded. Clinical evaluations at the diagnostic visit included measurement of visual acuity, manifest refraction and IOL orientation.Results: Eighteen eyes were evaluated. After secondary IOL implantation, mean residual refractive astigmatism was significantly reduced (1.66 ± 0.92 to 0.32 ± 0.25 D). There was no appreciable change in the spherical equivalent refraction. Sixteen of 18 eyes (89%) had residual refractive astigmatism ≤ 0.50D, and no eye had more than 0.75D after secondary IOL implantation. Mean UCVA was 0.00 ± 0.03 logMAR, with no eyes worse than 0.10. Mean BCVA was − 0.05 ± 0.03 logMAR (20/20+2), with all eyes having BCVA of 0.00 logMAR. The mean change in orientation was near zero, with a mean absolute change of 4.9 ± 3.7 degrees. Sixteen of 18 eyes (89%) had a lens orientation ≤ 10 degrees from intended, with no eye oriented more than 13 degrees from intended.Conclusion: The AddOn® toric sulcus IOL significantly reduced postoperative refractive astigmatism in patients with high astigmatism after their primary cataract or RLE surgery, providing very good uncorrected distance vision.Keywords: sulcus IOL, secondary IOL, AddOn toric, toric IOL |
