Title:
多焦点眼内レンズ及びその作成及び使用方法
Document Type and Number:
Japanese Patent JP4234584
Kind Code:
B2
Abstract:
This intraocular lens includes an optic body having anterior and posterior walls, a chamber, and optically transmissive primary and secondary fluids, and method for making and using the same. The secondary fluid is substantially immiscible with the primary fluid and has a different density and a different refractive index than the primary fluid. The primary fluid is present in a sufficient amount that orienting optical body optical axis horizontally for far vision positions the optical axis through the primary fluid, thereby immersing the anterior and posterior optical centers in the primary fluid. The secondary fluid is contained in the optic body in a sufficient amount that orienting the optical axis at a range of effective downward angles relative to the horizontal for near vision positions the optical axis to extend through the primary fluid and the secondary fluid, thus changing the focus of the intraocular lens.
