| 发明名称 | Method and apparatus for determining the location of the ocular pivot point | ||
| 摘要 | The invention relates to a method for determining the location of the ocular pivot point (ADL) in an eye (10) of a test person. In the method, the mean curvature (KH) of the cornea (14) of the eye (10) is determined. The mean phase error (PF) of the eye (10) is determined as is the eye length (LA) from the mean curvature (KH) and the mean phase error (PF). The location of the ocular pivot point (ADL) is determined from the eye length (LA). | ||

| 主权项 | 1. A method for determining the location of the ocular pivot point (ADL) in an eye of a test person, the method comprising the steps of: a) determining the mean curvature (KH) of the cornea of the eye; b) determining the mean phase error (PF) of the eye; c) determining the eye length (LA) from the mean curvature (KH) and the mean phase error (PF); and, d) determining the location of the ocular pivot point (ADL) from the eye length (LA); wherein the mean curvature (KH) and the mean phase error (PF) are determined with a spatial reference to at least one of a predetermined axis and a pupil center of the eye. | ||
