To assess the outcomes of implantation of a single-piece toric intraocular lens (IOL) with 4 fenestrated haptics.
IRCCS Fondazione Bietti, Rome, Italy.
Prospective case series.
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.
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).
The toric IOL showed good rotational stability and is an option for correcting corneal astigmatism at the time of cataract surgery.

前瞻性病例系列研究。
连续纳入所有植入 Mini Toric Ready IOL 的患者。术中使用自动系统对齐 IOL。在术后 1 天、1 周以及 1、3 和 6 个月进行随访。每次随访时，均通过背透光拍照评估 IOL 位置；同时还测量了视力和屈光度。
最终分析纳入 63 只眼（63 例患者）。从首次随访到末次随访，平均算术旋转为-0.2 度±3.5 （标准差）（范围-13 度至+10 度），平均绝对旋转为 1.6 度±3.1 度。92.1%的眼在 5 度以内旋转，在连续随访中，98.4%或更多的眼在 5 度以内旋转。6 个月时，10 只 IOL（15.9%）发生顺时针旋转，10 只发生逆时针旋转。线性回归显示，旋转稳定性与任何术前参数（如眼轴长度）之间没有统计学显著关系。术前角膜散光的平均大小为 1.9 度±0.7 屈光度（D）（范围 0.76 度至 3.72 D）。末次随访时，平均等效球镜屈光度为 0.5 度±0.4 D（范围 0.0 至 1.5 D）；差异具有统计学意义（P<.05）。
该散光 IOL 具有良好的旋转稳定性，是白内障手术时矫正角膜散光的一种选择。
