چکیده انگلیسی
This paper proposes an accommodating IOL with meniscus polymer membrane and porous structure based on the optical structure and focusing mechanism of the human eye. The fabrication procedure and forming characteristics of the meniscus membrane based on thermal and gravity assisting method are also presented. The proposed IOL mainly consists of two soft meniscus polymer layers, a porous support ring and optical liquid, which can be fixed in the capsular bag and adjusted by the ciliary muscle to change the focus. The structure and regulating principle of the IOL are presented, as well as the lens fabrication process. Additionally, the lens adjusting properties, imaging quality, surface roughness and physical density are also measured and analyzed. Under the radial pressure of 92.3 mN, the designed IOL can achieve a 13.5 D accommodating range. The presented IOL shows good accordance with the regulating process of the human eye, which can be used for the visual disturbance therapy and various optical zooming systems.
