PURPOSE
To evaluate the rotational stability of nontoric intraocular lenses (IOLs) of the same design and different materials.
SETTING
Vienna Institute for Research in Ocular Surgery, Department of Ophthalmology, Hanusch Hospital, Vienna, Austria.
DESIGN
Prospective randomized case series.
METHODS
This study included cataract patients with a corneal astigmatism of less than 1.75 diopters measured with the IOLMaster 500. Each patient received a hydrophilic IOL (Pod Ay 26P) in 1 eye and a hydrophobic IOL (Podeye) in the other eye. One hour and 3 months postoperatively, retroillumination photographs were taken to assess rotational stability of the IOLs. In addition, autorefraction, subjective refraction, and Purkinje meter measurements were performed at the 3-month follow-up.
RESULTS
Eighty eyes of 40 patients were included in this study. Three months postoperatively, the IOL rotation within the first 3 months was 2.4 degrees ± 1.85 (SD) in the hydrophilic IOL group and 1.6 ± 1.61 degrees in the hydrophobic IOL group. This difference was statistically significant (P = .016).
CONCLUSION
The hydrophobic IOL was rotationally more stable than the hydrophilic IOL, although both IOLs provided good capsular bag stability.
目的
评估相同设计但材料不同的非旋转性人工晶状体（IOL）的旋转稳定性。
地点
维也纳眼科研究所，维也纳哈努什医院眼科。
设计
前瞻性随机病例系列。
方法
本研究纳入了角膜散光小于 1.75 屈光度的白内障患者，使用 IOLMaster 500 进行测量。每位患者的一只眼植入亲水型 IOL（Pod Ay 26P），另一只眼植入疏水性 IOL（Podeye）。术后 1 小时和 3 个月，拍摄后照以评估 IOL 的旋转稳定性。此外，在 3 个月的随访中进行自动折射、主观折射和普尔金耶计测量。
结果
本研究共纳入 40 例 80 只眼。术后 3 个月，亲水型 IOL 组 IOL 在前 3 个月的旋转度为 2.4 度±1.85（标准差），疏水性 IOL 组为 1.6 度±1.61 度。差异具有统计学意义（P=.016）。
结论
尽管两种 IOL 均提供良好的囊袋稳定性，但疏水性 IOL 的旋转稳定性优于亲水型 IOL。
