PURPOSE To evaluate visual performance in patients implanted contralaterally and bilaterally with the small-aperture hydrophobic acrylic intraocular lens (IOL) (IC-8 IOL; AcuFocus, Irvine, CA). METHODS In this prospective, non-randomized, non-comparative study, 10 contralateral patients were implanted with a monofocal IOL in one eye and an IC-8 IOL in the other. There were 10 bilateral patients implanted with an IC-8 IOL in both eyes. All patients were observed for at least 12 months after the study device was implanted in each eye. Visual acuity, patient satisfaction, ease of task performance, visual symptoms, defocus curves, and contrast sensitivity comparisons are presented. RESULTS For bilateral and contralateral patients, the mean uncorrected and corrected distance binocular acuities were 20/25 or better at all distances. All 10 (100%) contralateral and 10 (100%) bilateral patients achieved 20/32 or better binocular uncorrected and corrected distance visual acuity at all distances. The improvement in binocular uncorrected intermediate and uncorrected near visual acuity was 0.5 to 1 line greater in bilateral patients. Bilateral implantation extended the depth focus range by 0.25 diopters. The mean log contrast sensitivity was similar in both groups for mesopic without glare and with glare conditions at all spatial frequencies (P > .05). Bilateral patients had better overall satisfaction, satisfaction with near tasks, and spectacle independence and they rated many near tasks as easier to perform. CONCLUSIONS Results demonstrate that both contralateral and bilateral implantation of an IC-8 IOL provide excellent visual acuity across all distances. Bilateral implantation can be successful based on careful patient selection and optimization of refractive targets. [J Refract Surg. 2020;36(1):12-19.].

小孔人工晶状体的视觉性能：对侧和双侧植入后结果的首次比较。

目的评估小孔疏水性丙烯酸丙烯酸人工晶状体（IOL）（IC-8 IOL； AcuFocus，Irvine，CA）对侧和双侧植入患者的视觉性能。方法在这项前瞻性，非随机，非对照研究中，10例对侧患者的一只眼睛植入了单焦点IOL，另一只眼睛植入了IC-8 IOL。双眼有10名双侧患者植入了IC-8 IOL。在将研究装置植入每只眼睛后，对所有患者进行了至少12个月的观察。介绍了视力，患者满意度，任务执行的便利性，视觉症状，散焦曲线和对比敏感度比较。结果对于双侧和对侧患者，在所有距离上，未矫正和矫正的距离双眼平均视力为20/25或更好。所有10名（100％）对侧和10名（100％）双侧患者在所有距离上均达到20/32或更好的双眼未矫正和矫正远视力。在双侧患者中，双眼未矫正的中间和未矫正的近视力的改善大0.5至1行。双边植入将深度聚焦范围扩大了0.25屈光度。在没有眩光和在所有空间频率下有眩光条件的情况下，两组的平均对数对比灵敏度相似（P> .05）。双边患者的总体满意度更高，对近期任务的满意度更高，并且眼镜独立性更高，他们认为许多近期任务更容易执行。结论结果表明，对侧和双侧植入IC-8 IOL均可在所有距离上提供出色的视敏度。基于患者的仔细选择和屈光目标的优化，双侧植入可以成功。[J Refract Surg。2020; 36（1）：12-19。]。
