Title:
残余調節力を利用した有水晶体多焦点光学素子を用いた中間視の向上
Document Type and Number:
Japanese Patent JP2010515549
Kind Code:
A
Abstract:
In one aspect, the present invention provides a method of correcting vision, which comprises determining a residual accommodation exhibited by a natural, crystalline lens of an eye, and selecting a multifocal intraocular lens (IOL), which exhibits a far-focus optical power (e.g., in a range of about −15 to about +50 Diopters (D)) and an add power (e.g., in a range of about 1 D to about 4 D), for implantation in the eye while retaining the natural lens. The add power of the IOL is selected as a function of the residual accommodation such that a combination of the IOL and the natural lens provides a visual contrast greater than about 10% at a spatial frequency of about 20 cycles/degree for viewing objects at a distance greater than about 30 cm from the eye.
