TH105160B - Near-distant adjustable intraocular lens (IOL) with astigmatic lens center And the depth of the focal point increases - Google Patents

Abstract

On the one hand, the invention provides an artificial intraocular lens consisting of a Two or more parts arranged along the optical axis. And a mechanism to adjust the distance near the body connected to the At least part of the lens and is adjusted to adjust the optical power of the lens body to It responds to the natural near-far focusing power of the eye where the lens is introduced. Can be implanted internally to make near-distant adjustments At least one lens has The surface looks like the first refractive area. The second refractive area and the transitional area at Is between these two areas Where the distance displacement of the incident light is The long designed wave (ie, 550 nm) that crosses the transitional area corresponds to the fraction. That does not use an integer of the design wavelength

Claims (1)

1. Intraocular lens Containing At least two parts of the lens that line the optical axis. A close-up mechanism that is connected to at least one part of the lens and is Adjusted to adjust the total light power of the lens to match the near focusing power. The natural distance of the eye, where the lens is implanted inside. At least one such lens has a surface that is the second refracting area, the second refracting area, and the transition area between the two. Where shifting
