To evaluate the influences of preoperative pupil parameters on the visual outcomes of the SBL-3, a rotationally asymmetric multifocal intraocular lens (IOL) with a surface-embedded near segment.

Retrospective comparative case series.
Postoperatively, patients divided into 4 groups according to their pupil size as follows: Group A: 2.50 to 2.99 mm, Group B: 3.00 to 3.50 mm, Group C: 3.51 to 4.00 mm, and Group D: 4.01 to 4.50 mm. The uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities, IOL centration and tilt, and quality of vision (QoV) questionnaires were compared between the 4 groups for 18 months postoperatively.
The study comprised 90 patients (180 eyes). The mean preoperative pupil (photopic and mesopic) diameter was 4.3 mm ± 0.3 (SD) and 5.6 ± 1.4 mm, respectively, which decreased to 3.8 ± 0.7 mm and 4.9 ± 1.2 mm, respectively, at 18 months. Eighteen months postoperatively, both photopic and mesopic pupil groups had a statistically significant reduction in size from preoperative levels. No significant differences in UDVA, UIVA, and UNVA were found between the groups (P > .001). Significant differences in the QoV questionnaire day scores and night scores were found between the 4 groups (P < .001).
The rotationally asymmetric multifocal IOL provided excellent optical performance during 18-months follow-up. The preoperative photopic pupil is an important parameter for consideration of this type of IOL because smaller pupils have a significant negative subjective impact on QoV.
评估术前瞳孔参数对 SBL-3 的视觉效果的影响，SBL-3 是一种具有表面嵌入式近节段的旋转不对称多焦点人工晶状体（IOL）。

回顾性比较病例系列。
术后根据瞳孔大小将患者分为 4 组：A 组：2.50 至 2.99mm；B 组：3.00 至 3.50mm；C 组：3.51 至 4.00mm；D 组：4.01 至 4.50mm。术后 18 个月比较 4 组的未矫正距离（UDVA）、中间距离（UIVA）和近距（UNVA）视力、IOL 中心和倾斜度以及视觉质量（QoV）问卷。
本研究共纳入 90 例（180 只眼）患者。平均术前瞳孔（明视和中间）直径分别为 4.3±0.3（SD）和 5.6±1.4mm，术后 18 个月分别降至 3.8±0.7mm 和 4.9±1.2mm。术后 18 个月，明视和中间瞳孔组的瞳孔均较术前显著缩小。各组间 UDVA、UIVA 和 UNVA 差异均无统计学意义（P>.001）。4 组 QoV 问卷日间和夜间评分差异均有统计学意义（P<.001）。
旋转不对称多焦点 IOL 在 18 个月的随访中提供了出色的光学性能。术前明视瞳孔是考虑这种 IOL 的重要参数，因为较小的瞳孔对 QoV 有显著的负面影响。
