To compare the quality of images viewed through an extended depth of focus (EDF) intraocular lens (IOL) to that through multifocal or monofocal IOL.
Experimental study METHODS: EDF IOL (Symfony, ZXR00V, Johnson & Johnson Vision), diffractive multifocal (ZLB00, + 3.25D or ZMB00, + 4.0D), or monofocal (ZCB00V) IOL with a spherical power of + 20.0 diopter (D) was placed in a fluid-filled model eye with corneal aberrations similar to those of human eyes. A United States Air Force Resolution Grating Target was glued to the posterior surface of the model eye and viewed through a flat contact lens, a 60D or 128D wide-angle non-contact lens (Resight) or wide-angle contact lens (MiniQuad). The contrast of the grating images recorded with the EDF and multifocal IOLs were compared to those through the monofocal IOL.
The grating images viewed through the flat contact lens were slightly blurred when viewed through the EDF IOL but clearer than those through the multifocal IOLs with very blurred images in the periphery. The contrast of the images viewed through the EDF and multifocal IOLs through the flat contact lens was significantly lower than through the monofocal IOL (P < 0.02). The contrast of the images viewed through the EDF IOL with 60D or 128D wide-angle non-contact lens was significantly lower than through the monofocal IOL (P < 0.05) but not with wide-angle contact lens.
Our results suggest that vitreous surgeons can accomplish a clearer view during vitrectomy in EDF IOL-implanted eyes with a wide-angle viewing contact lens and a flat contact lens than in multifocal IOL-implanted eyes.
比较通过扩展景深（EDF）人工晶状体（IOL）观察到的图像质量与通过多焦点或单焦点IOL观察到的图像质量。
实验研究
将具有+20.0屈光度（D）球面屈光力的EDF IOL（Symfony，ZXR00V，强生视力）、衍射多焦点IOL（ZLB00，+3.25D或ZMB00，+4.0D）或单焦点IOL（ZCB00V）植入具有与人眼相似角膜像差的充满液体的模型眼中。将美国空军分辨率光栅靶粘贴到模型眼的后表面，并通过平面隐形眼镜、60D或128D广角非接触镜（Resight）或广角隐形眼镜（MiniQuad）进行观察。将用EDF和多焦点IOL记录的光栅图像的对比度与通过单焦点IOL记录的对比度进行比较。
通过平面隐形眼镜观察时，通过EDF IOL观察到的光栅图像略显模糊，但比通过多焦点IOL观察到的图像更清晰，多焦点IOL观察到的图像在外围非常模糊。通过平面隐形眼镜观察时，通过EDF和多焦点IOL观察到的图像对比度明显低于通过单焦点IOL观察到的对比度（P<0.02）。通过60D或128D广角非接触镜观察时，通过EDF IOL观察到的图像对比度明显低于通过单焦点IOL观察到的对比度（P<0.05），但通过广角隐形眼镜观察时并非如此。
我们的结果表明，玻璃体手术医生在使用广角观察隐形眼镜和平面隐形眼镜进行玻璃体切除术时，在植入EDF IOL的眼中比在植入多焦点IOL的眼中能获得更清晰的视野。
