To prospectively evaluate surgical results following implantation of rotationally asymmetric, plate-haptic, refractive segmented multifocal toric intraocular lenses (IOLs) with near addition of + 1.5 diopters (D) (Lentis Comfort LS-313 MF15T, Oculentis GmbH).
In 59 eyes of 41 patients, ocular examinations were conducted before and 1 day, 1 week, 1, 3, and 6 months after surgery. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity at 70 cm, and uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 30 cm were tested. A defocus curve was drawn, and the degree of disturbing photic phenomena were questioned.
The IOL showed excellent rotational stability; the average absolute rotation was 1.66 ± 1.17 degrees from 1 day 1 to 6 months postoperatively, and 98.1 and 100% of eyes yielded rotation of less than 5 and 10 degrees, respectively. Postoperative distance and intermediate visual acuity were highly satisfactory; UDVA, CDVA, UIVA, and DCIVA were about 20/20, 20/16, 20/25, 20/25, respectively. Near visual acuity was suboptimal; UNVA and DCNVA were at approximately 20/60. The defocus curve analysis showed that 20/25 and 20/40 uncorrected visual acuity was attained at as close as 60 and 40 cm, respectively. Contrast sensitivity was within a normal range, and subjective photic phenomena were minimum.
The refractive segmented, rotationally asymmetric multifocal toric IOLs with + 1.5 D near addition showed superb rotational stability and highly satisfactory distance and intermediate vision. Contrast sensitivity was high and incidence of photic symptoms was very low.

前瞻性评估植入旋转不对称、板状、折射分段多焦点散光人工晶状体（IOL）的手术效果，该 IOL 附加近距 +1.5 屈光度（D）（Lentis Comfort LS-313 MF15T，Oculentis GmbH）。
41 例 59 眼中，术前及术后 1 天、1 周、1、3、6 个月进行眼部检查。检测未矫正（UDVA）和矫正（CDVA）远距视力、70cm 处未矫正（UIVA）和远距矫正（DCIVA）中间视力、30cm 处未矫正（UNVA）和远距矫正（DCNVA）近距视力。绘制离焦曲线，并询问光干扰现象的程度。
IOL 显示出极好的旋转稳定性；术后 1 天至 6 个月平均绝对旋转为 1.66±1.17 度，98.1%和 100%的眼旋转角度小于 5 度和 10 度。术后远距和中间视力非常满意；UDVA、CDVA、UIVA 和 DCIVA 分别约为 20/20、20/16、20/25、20/25。近距视力欠佳；UNVA 和 DCNVA 约为 20/60。离焦曲线分析显示，20/25 和 20/40 未矫正视力分别在 60cm 和 40cm 左右即可获得。对比敏感度处于正常范围内，主观光干扰现象最小。
附加+1.5D 近距的折射分段、旋转不对称多焦点散光 IOL 具有极好的旋转稳定性和非常满意的远距和中间视力。对比敏感度高，光症状发生率低。
