PURPOSE Clinical evaluation of the visual outcomes after implantation of a small-aperture extended depth of focus (EDOF) intraocular lens (IOL) and a segmental refractive bifocal lens. METHODS In this prospective study, 13 patients with cataract received a small-aperture IC-8 IOL (AcuFocus, Irvine, CA) in one eye and a segmental-refractive Lentis Mplus LS-313 MF20 IOL (Oculentis, Berlin, Germany) in the fellow eye. The clinical examination included measurements of uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity, and uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity. Additionally, a defocus curve was obtained from +2.00 to -5.00 diopters (D) and a Salzburg Reading Desk was used to assess the patients' reading acuity at intermediate and near distances. A halo and glare simulator was used to evaluate the postoperative perception of dysphotopsia. RESULTS At 5 months postoperatively, the mean binocular visual results demonstrated UDVA, UIVA, and UNVA values of -0.04 ± 0.11, 0.00 ± 0.10, and 0.11 ± 0.08 logMAR, respectively. The binocular distance-corrected reading performance test also confirmed the improved visual function, with an intermediate reading acuity of 0.12 logMAR at 69.21 cm and a near reading acuity of 0.19 logMAR at 41.63 cm. The mean halo size was 32.54 ± 22.38, mean halo intensity was 34.46 ± 21.95, mean glare size was 9.00 ± 17.47, and mean glare intensity was 9.92 ± 16.84. CONCLUSIONS The new concept of a combined implantation of a small-aperture IOL and a segmental-refractive bifocal lens showed good results in far and intermediate distances and functional results at near distance, while causing minimal photic phenomena.

小孔径镜片和分段屈光双焦点镜片联合植入后的功能结果和阅读性能。

目的对小口径扩展景深（EDOF）人工晶状体（IOL）和分段屈光双焦点晶状体植入后的视觉效果进行临床评估。方法在这项前瞻性研究中，13例白内障患者的一只眼睛接受了小口径IC-8 IOL（AcuFocus，Irvine，CA），而部分屈光性Lentis Mplus LS-313 MF20 IOL（Oculentis，柏林，德国）接受了治疗。同伴的眼睛。临床检查包括未矫正（UDVA）和矫正（CDVA）远视力，未矫正（UIVA）和距离矫正（DCIVA）中间视力以及未矫正（UNVA）和距离矫正（DCNVA）的近视力的测量。此外，散焦曲线从+2.00屈光度到-5.00屈光度（D），并使用萨尔茨堡阅览桌评估患者的 中距离和近距离的阅读敏锐度。光晕和眩光模拟器用于评估对光敏异常的术后知觉。结果术后5个月，平均双眼视觉结果显示UDVA，UIVA和UNVA值分别为-0.04±0.11、0.00±0.10和0.11±0.08 logMAR。双眼距离校正的阅读性能测试还证实了视觉功能的改善，在69.21 cm处的中间阅读灵敏度为0.12 logMAR，在41.63 cm处的中等阅读灵敏度为0.19 logMAR。平均光晕大小为32.54±22.38，平均光晕强度为34.46±21.95，平均眩光大小为9.00±17.47，平均眩光强度为9.92±16.84。结论小孔IOL和分段屈光双焦点镜片联合植入的新概念在远距离和中间距离以及近距离的功能结果方面显示出良好的效果，同时又将光合现象降至最低。[J Refract Surg。2019; 35（9）：551-558。]。
