| Abstract | Purpose To evaluate the clinical outcomes after implantation of Symfony® toric extended range of vision (ERV) intraocular lenses (IOLs) in subjects with preoperative corneal astigmatism. Setting Ifocus Øyeklinikk, Haugesund, Norway. Design Prospective non-comparative study. Patients and methods The study population consisted of 30 patients, with preoperative corneal astigmatism between 0.88 and 3.29 D, undergoing bilateral cataract removal or refractive lens exchange with implantation of Tecnis Symfony toric ERV IOLs. Main outcome measures were visual acuity, refraction, IOL axis rotational stability, patient and surgeon satisfaction, photic phenomena, and quality of life at 3 months. Results Postoperatively, mean binocular uncorrected distance, intermediate, and near visual acuities (logMAR) were -0.05±0.11, -0.03±0.08, and 0.09±0.10, respectively. A significant reduction in manifest cylinder (P<0.001) and spherical equivalent (P=0.001) was found after 3 months. Monocular and binocular corrected distance visual acuity also improved significantly with surgery (P<0.001). In terms of binocular uncorrected intermediate and near visual acuity, a total of 96% and 82% of patients achieved 0.1 logMAR (Snellen: 20/25) or better, respectively. Toric IOL axis showed a median rotation of 2.0 degrees (range 0.0-16.0 degrees) from the end of surgery to 3 months. The median patient satisfaction scores for distance, intermediate, and near vision were 9.0, 9.0, and 8.0, respectively. Fifty percent of patients reported complete spectacle independence and most patients (89%) were not bothered by any photic phenomena. Conclusion Bilateral implantation of the Symfony toric ERV IOL appeared to be safe and achieved good visual performance and high satisfaction. |
