虽然隐形眼镜的制造工艺已经很成熟，但使用增材制造来制造隐形眼镜开辟了许多新的可能性。目前的研究展示了利用增材制造来制造个性化智能合约镜片。该研究包括在基于标准商业接触透镜尺寸的计算机辅助设计工具的帮助下进行接触镜片的三维（3D）建模，然后选择合适的材料和接触镜片的3D打印。优化3D打印参数以实现所需的透镜几何形状，并进行后加工处理以实现光滑的表面光洁度。这项研究还提出了功能化的隐形眼镜内置的传感能力，通过利用微通道在接触透镜边缘。印刷着色的接触透镜，并通过全息激光烧蚀将纳米颗粒纹理化到接触透镜表面上。3D打印隐形眼镜比传统隐形眼镜具有优势，提供定制的眼科设备以及与光学传感器集成进行诊断的能力。
Although the manufacturing processes of contact lenses are well established, the use of additive manufacturing for their fabrication opens many new possibilities to explore. The current study demonstrates the fabrication of personalized smart contract lenses utilizing additive manufacturing. The study includes 3-dimensional (3D) modeling of contact lenses with the assistance of a computer aided designing tool based on standard commercial contact lens dimension, followed by the selection of the suitable materials and 3D printing of contact lenses. The 3D printing parameters were optimized to achieve the desired lens geometries, and a post processing treatment was performed to achieve a smooth surface finish. The study also presents functionalized contact lenses with built-in sensing abilities by utilizing microchannels at the contact lens edges. Tinted contact lenses were printed and nanopatterns were textured onto the contact lens surfaces through holographic laser ablation. 3D printed contact lenses have advantages over conventional contact lenses, offering customized ophthalmic devices and the capability to integrate with optical sensors for diagnostics.
