    • The new variable power accommodative intraocular lens is comprised by a central body or optical zone that has at least four refracting interfaces that separate different materials. These are connected by means of a substrate that holds them in an equatorial manner, and which includes the bases of the fasteners of the lens embedded in its core. The lens changes its power in response to variations in the equatorial diameter of the materials that comprise the optical zone. Thanks to its design, the lens can achieve variations in the optical powers greater than one dioptre per micrometre of equatorial compression. This is achieved through the real change of the curvature radii of the refracting interfaces that comprise the optical zone, as well as the central thicknesses along the length of the optical axis of the different materials that limit said refracting interfaces. Preferably the intraocular lens works in combination with a capsular ring, to which the haptics are fixed and whose external diameter determines the power of the lens. The change of power mechanism in the lens initiates with the contraction of the ciliary muscle of the patient in response to the accommodative force.
    • 新的可变动力调节眼内透镜由具有至少四个分离不同材料的折射界面的中心体或光学区域组成。 它们通过以赤道方式保持它们的基板连接,并且其包括嵌入其芯中的透镜的紧固件的基部。 镜片根据构成光学区域的材料的赤道直径的变化而改变其功率。 由于其设计,透镜可以实现大于一微秒的每微米赤道压缩的光功率的变化。 这通过包括光学区域的折射界面的曲率半径的真实变化以及沿着限制所述折射界面的不同材料的光轴的长度的中心厚度来实现。 优选地,眼内透镜与荚膜组合起来,襻被固定到其上,并且其外径决定透镜的力量。 透镜中功率机制的变化开始于患者的睫状肌受到调节力的收缩。
