Analysis of crystalline lens position

Abstract: The crystalline lens was not aligned perfectly along the visual axis, but its effect on refraction was limited.

“…In this study, we used the IOLMaster 700 to measure ocular parameters, including the position of the crystalline lens. Other methods have previously been used to measure IOL tilt and decentration, such as ultrasound biomicroscopy [26], anterior-segment OCT [27], and Purkinje and Scheimpflug imaging [28][29][30]. In those studies, measurements were made with reference to different planes or axes, including the iris plane, the corneal topographic axis, the pupillary axis, and the visual axis.…”

“…der Kunstlinse im pseudophaken Auge nach einer Kataraktoperation konnte für viele Jahre nur abgeschätzt werden [22]. Zur Verfügung standen dafür optische Messverfahren wie Purkinje-Meter oder Scheimpflug-Kameras [4,6,16]. Allerdings ist speziell bei Scheimpflug-Kameras das Messfeld in axiale Richtung deutlich begrenzt, da die Einhaltung der Scheimpflug-Bedingung voraussetzt, dass die Bildebene, die Linsenebene sowie die Ebene der Spaltbeleuchtung in eine Linie schneiden.…”

“…A 14°tilt around the vertical axis of the crystalline lens would theoretically give this amount of RA 50 (p.209) . Actually, the tilt of the crystalline lens is much smaller 72,73 , which points to the posterior corneal surface as the source of the RA. Both anterior and posterior corneal surfaces have the same principal meridians 74 .…”
