Age-related macular degeneration is a leading cause of visual loss in adults older than 60 years of age. Once vision has been seriously compromised, the only means of improving visual function are optical devices that produce magnification of images. These devices fall into three categories: (1) high-plus lenses, (2) external telescopes, and (3) a high-minus center intraocular lens combined with external high-plus glasses. The authors designed a new intraocular lens with an entire telescope in its center. In vitro tests were performed to evaluate modulation transfer function, visual field, and optical aberrations. Implantation in cadaver eyes was performed to test the surgical technique and safety. Test results showed that satisfactory modulation transfer function and optic aberration were achieved, and implantation in cadaver eyes was proven to be feasible and safe. It was concluded that a fully implanted intraocular telescopic lens is an effective optical solution for age-related macular degeneration.
年龄相关性黄斑变性是60岁以上成年人视力丧失的主要原因。一旦视力严重受损,改善视觉功能的唯一方法是使用能放大图像的光学设备。这些设备分为三类:(1)高度数凸透镜,(2)外置望远镜,(3)高度数凹透镜中心的人工晶状体联合外置高度数眼镜。作者设计了一种新型人工晶状体,其中心内置完整的望远镜。进行了体外测试以评估调制传递函数、视野和光学像差。在尸体眼中进行植入以测试手术技术和安全性。测试结果表明,获得了令人满意的调制传递函数和光学像差,并且在尸体眼中植入被证明是可行和安全的。得出的结论是,完全植入式人工晶状体望远镜是治疗年龄相关性黄斑变性的一种有效的光学解决方案。
