Encouraging Visual Outcome of a New Accommodative Intraocular Lens: A Retrospective Long-Term Study with a Mean Follow-Up of 5.3 Years

Purpose: To assess the visual outcome after implantation of the new Hydrophylic IOL type 41 B/G accommodating intraocular lens (AIOL). Methods: The presented lens was implanted during cataract surgery. All patients were offered follow-ups, allowing two postoperative measurements to be performed at 3 months and between 2020 and 2021. The mean time between lens implantation and last follow-up was 5.3 years (min. 1 year, max. 10 years). Excluded were patients with age-related macular degeneration or amblyopia. Patients with a foreign lens implanted into the second eye were included in a separate control group. Corrected distance (CDVA) and uncorrected distance visual acuity (UDVA) at 5 m, and corrected near (CNVA) and uncorrected near visual acuity (UNVA) at 40 cm were assessed. Furthermore, the postoperative spherical equivalent (SE), the dependence on spectacles and the occurrence of optical phenomena were evaluated. Results: The final study cohort consists of 65 patients with 119 implanted AIOLs. Significantly better visual results were obtained in both postoperative follow-ups compared with the preoperative results. The mean values of the last follow-up for the UNVA, CNVA, UDVA, and CDVA were 0.107 ± 0.10; 0.039 ± 0.08; 0.097 ± 0.11; and 0.040 ± 0.09 logMAR, respectively. Visual outcomes remained on a high level for up to 10 years and showed significantly better results compared to the control group. Postoperative SE was significantly improved. Nearly 70% of patients were no longer dependent on glasses. Furthermore, the occurrence of disturbing optical phenomena was denied by all patients. Conclusion: The results of this AIOL are particularly promising, especially since gratifying visual results could still be measured 10 years after implantation.
