PURPOSE To assess the outcomes of implantation of a single-piece toric intraocular lens (IOL) with 4 fenestrated haptics. SETTING IRCCS Fondazione Bietti, Rome, Italy. DESIGN Prospective case series. METHODS All patients who had implantation of the Mini Toric Ready IOL were consecutively enrolled. Intraoperatively, the IOL was aligned using an automated system. Follow-up visits were performed at 1 day, 1 week, and 1, 3, and 6 months. At each visit, retroillumination pictures were taken to assess IOL orientation; visual acuity and refraction were also measured. RESULTS The final analysis comprised 63 eyes (63 patients). From the first to the last follow-up, the mean arithmetic rotation was -0.2 degrees ± 3.5 (SD) (range -13 to +10 degrees) and the mean absolute rotation was 1.6 ± 3.1 degrees. Intraocular lens rotation from the first to the last examination was within 5 degrees in 92.1% of eyes and on consecutive visits, within 5 degrees in 98.4% or more of eyes. By 6 months, 10 IOLs (15.9%) had rotated clockwise and 10 counterclockwise. Linear regression did not show a statistically significant relationship between rotational stability and the axis of placement with any preoperative parameter (eg, axial length). The mean magnitude of preexisting corneal astigmatism was 1.9 ± 0.7 diopters (D) (range 0.76 to 3.72 D). At the last follow-up, the mean magnitude of refractive astigmatism was 0.5 ± 0.4 D (range 0.0 to 1.5 D); the difference was statistically significant (P < .05). CONCLUSION The toric IOL showed good rotational stability and is an option for correcting corneal astigmatism at the time of cataract surgery.

具有4个开孔触觉的单片非球面复曲面人工晶状体的旋转稳定性和屈光结果。

目的评估具有4个开窗式触觉的复曲面复式人工晶状体（IOL）的植入效果。设置IRCCS Fondazione Bietti，意大利罗马。设计预期案例系列。方法所有接受Mini Toric Ready IOL植入的患者均被纳入研究。术中，使用自动系统对IOL进行校准。在1天，1周，1、3和6个月进行随访。每次拜访时，都需要进行回顾照明图片以评估IOL方向；还测量了视力和屈光度。结果最终分析包括63眼（63例患者）。从第一次随访到最后一次随访，平均算术旋转为-0.2度±3.5（SD）（范围为-13至+10度），平均绝对旋转为1.6±3.1度。从第一次检查到最后一次检查，眼内晶状体旋转在92.1％的眼睛中在5度以内，在连续就诊时，在98.4％或以上的眼睛中在5度以内。到6个月时，已经有10个IOL（15.9％）顺时针旋转，逆时针旋转10个。线性回归未显示任何术前参数（例如，轴向长度）在旋转稳定性和放置轴之间的统计学意义上的显着关系。既有角膜散光的平均幅度为1.9±0.7屈光度（D）（范围0.76至3.72 D）。在最后一次随访中，屈光散光的平均幅度为0.5±0.4 D（范围为0.0到1.5 D）。差异具有统计学意义（P <.05）。结论复曲面IOL表现出良好的旋转稳定性，是白内障手术时矫正角膜散光的一种选择。
