Abstract
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 surgery3months to 1year before study recruitment. Inallcases, Purkinje meter images were taken. In addition, partialcoherence interferometry measurement (IOLMaster) ofthe axial intraocular lens (IOL) position was performed. Inasubgroup of patients, an additional Hartmann-Shacksensor 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 74.1years±8.6 (SD) (range 44 to 91years). The mean tilt (pupillary axis) and decentration were 3.9±2.3 degrees (range 0.2 to 16.2 degrees) and 0.4±0.2mm (range 0.0 to 1.7mm), 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.
