Design of multi-focus intraocular lenses

  • 摘要: 运用Zemax光学设计软件构建Liou-Brennan眼模型,设计了增大焦深的非球面、折射型多焦点和衍射型多焦点人工晶体,并用点列图和视锐度分析了所设计的人工晶体的光学质量。对于非球面人工晶体,在3 mm瞳孔下,当人眼无球差时,最佳视锐度相当高,但焦深仅为1.4 m-1;当人眼球差为0.4时,最佳视锐度可达0.9,焦深达2.2 m-1,同时在整个焦深范围内视觉质量均优越。对于衍射型和折射型多焦点人工晶体,在明视条件下,虽然视远和视近时视觉质量良好,但是中间距离的视锐度0.5。衍射型多焦点人工晶体只有81%的光能用于成像,远近焦点能量均分,且与瞳孔大小无关;折射型多焦点人工晶体的远近焦点能量与瞳孔大小相关。设计的人工晶体均能增大人眼的焦深,但各有优缺点,临床上应该酌情选用。
