To observe the variability in angle κ in pseudophakic patients and assess its correlation with optical biometry measurements and higher-order aberrations (HOAs).
Hanusch Hospital, Vienna, Austria.
Prospective case series.
This study included patients who had cataract surgery 3 months to 1 year before study recruitment. In all cases, Purkinje meter images were taken. In addition, partial coherence interferometry measurement (IOLMaster) of the axial intraocular lens (IOL) position was performed. In a subgroup of patients, an additional Hartmann-Shack sensor measurement was taken to assess HOAs (WASCA).
This study comprised 395 eyes of 349 patients. The mean age of the 210 women and 139 men was 74.1 years ± 8.6 (SD) (range 44 to 91 years). The mean tilt (pupillary axis) and decentration were 3.9 ± 2.3 degrees (range 0.2 to 16.2 degrees) and 0.4 ± 0.2 mm (range 0.0 to 1.7 mm), respectively. The mean angle κ was 5.2 ± 2.6 degrees (range 0.3 to 13.9 degrees), and the mean orientation of this modulus was 189.5 ± 53.2 degrees (range 25.3 to 339.7 degrees).
The variability in the angle κ was high.

前瞻性病例系列。
本研究纳入了白内障手术后 3 个月至 1 年前招募的患者。所有病例均行普尔金耶氏像差仪（Purkinje meter）检查，并进行了眼轴内人工晶状体（IOL）位置的部分相干干涉测量（IOLMaster）。在部分患者中，还进行了哈特曼-夏克传感器（Hartmann-Shack sensor）测量，以评估高阶像差（WASCA）。
本研究共纳入 349 例患者的 395 只眼。210 名女性和 139 名男性的平均年龄为 74.1 ± 8.6 岁（标准差）（范围 44 至 91 岁）。平均倾斜（瞳孔轴）和偏心距分别为 3.9 ± 2.3 度（范围 0.2 至 16.2 度）和 0.4 ± 0.2 毫米（范围 0.0 至 1.7 毫米）。平均 κ 角为 5.2 ± 2.6 度（范围 0.3 至 13.9 度），该角的平均方位为 189.5 ± 53.2 度（范围 25.3 至 339.7 度）。
κ 角的变异性较大。
