Abstract
This work presents the first models of light sword intraocular lenses (LS IOLs) with angularly modulated optical power. We performed an experimental, comparative study with multifocal and extended depth of focus intraocular lenses, which are available on the market. The measurements conducted in an original optical bench were utilised for an analysis of point spread functions, elongated foci, modulation transfer functions and the areas defined by them. The LS IOL models perform homogeneous imaging in the whole range of designed defocus. The proposed concept of extended depth of focus seems to be promising for the development of presbyopia-correcting intraocular lenses capable of regaining fully functional vision.
摘要
这项工作展示了首批具有角度调制光焦度的光剑人工晶状体（LS人工晶状体）模型。我们对市场上现有的多焦点和扩展焦深人工晶状体进行了实验性对比研究。在一个原始光学平台上进行的测量被用于分析点扩散函数、拉长焦点、调制传递函数以及由它们定义的区域。LS人工晶状体模型在整个设计的散焦范围内都能实现均匀成像。所提出的扩展焦深概念对于开发能够恢复完全功能性视力的老花眼矫正人工晶状体似乎很有前景。
