Title:
INTRAOCULAR LENS INSPECTION APPARATUS
Document Type and Number:
Japanese Patent JP2013015345
Kind Code:
A
Abstract:

To provide an intraocular lens inspection apparatus which is capable of appropriately confirming the state of generating glare that may be generated when an intraocular lens is implanted in an eye.

An intraocular lens inspection apparatus which measures optical characteristics of an intraocular lens comprises a model eye unit, a light source unit and a turning mechanism. The model eye unit includes a cornea model lens having a curved surface matched to a cornea curvature of a human eye, a screen having a curved surface matched to a retina curvature, and an attaching/detaching part provided between the cornea model lens and the screen for removably installing the intraocular lens at a position corresponding to a distance from the cornea of the human eye to a crystalline lens with respect to the cornea model lens. The light source unit is provided for irradiating the model eye unit with light flux having a predetermined spread. The turning mechanism is provided for turning at least one of the model eye unit and the light source unit in order to change an incident angle of an optical axis center of the light flux to the cornea model lens.
