110 N.X. Nguyen · A. Langenbucher · B. Seitz, et al. FINAL COMMENTS The 1CU (HumanOptics AG, Erlangen, Germany) is an acrylic hydrophilic foldable single-piece PCIOL with a spherical optic diameter of 5.5 mm and a total diameter of 9.8 mm. This PCIOL is intended to allow accommodation by anterior movement of the optic (focus shift) secondary to contraction of the ciliary muscle.To achieve this,the lens haptics are modified with transmission elements at their fusion with the lens optic.With adequate indication and surgical technique, the 1CU IOL has been safe and effective in our hands. Even though the amount of additional pseudophakic accommodation that is achieved in patients with accommodative 1CU was relatively limited (depending on the measurement method, an excess of between 0.67 and 1.21 D in comparison with the control group with conventional PCIOL), the degree of additional pseudophakic accommodation is useful for the patients in daily life. The rate and postoperative time point of significant PCO necessitating Nd:YAG capsulotomy in our patients with 1CU are equal to results after implantation of hydrophilic acrylic IOLs reported in the literature. After uncomplicated capsulotomy, pseudophakic accommodation capabilities were completely restored compared to the results before occurrence of PCO. One potential drawback of evaluation of pseudophakic accommodation in our patients with 1CU was that objective measurement methods were not used to quantify pseudophakic accommodation at the various time points. However, there is a lack of measurement methods for use in clinical studies that are easily applicable to patients and that allow exact measurements of pseudophakic accommodation. Recent studies have indicated that after application of miotics, measurement of anterior chamber depth in pseudophakic eyes does not always give accurate, valuable and reproducible results. However, the results of our studies obtained by different examination methods (near visual acuity with best corrected distance refraction, subjective near point, defocusing and streak retinoscopy) indicate good visual function and accommodation ability of the accommodative 1CU PCIOL. Future research should be directed to improving further the optic and accommodative results of this new generation of accommodative PCIOLs. References 1.
