由于眼睛的复杂结构,眼部药物输送仍然是一个巨大的挑战。在这里,我们介绍了一种独特的眼部药物输送平台,通过硅纳米针与泪液可溶隐形眼镜的集成。硅纳米针可以以微创的方式渗透到角膜中,然后在几个月的过程中逐渐降解,从而实现无痛和长期持续的眼科药物输送。这种可撕裂的隐形眼镜可以适合各种大小的角膜,然后在一分钟内迅速溶解在泪液中,使抗炎药物能够最初突然释放。我们在兔模型中展示了该平台在有效治疗慢性眼部疾病(如角膜新生血管)方面的有效性,而没有显示出比目前标准治疗方法明显的副作用。该平台也可用于治疗其他慢性眼病。通过硅纳米针的创新,实现了无痛和长期持续的眼科药物输送。
Ocular drug delivery remains a grand challenge due to the complex structure of the eye. Here, we introduce a unique platform of ocular drug delivery through the integration of silicon nanoneedles with a tear-soluble contact lens. The silicon nanoneedles can penetrate into the cornea in a minimally invasive manner and then undergo gradual degradation over the course of months, enabling painless and long-term sustained delivery of ocular drugs. The tear-soluble contact lens can fit a variety of corneal sizes and then quickly dissolve in tear fluid within a minute, enabling an initial burst release of anti-inflammatory drugs. We demonstrated the utility of this platform in effectively treating a chronic ocular disease, such as corneal neovascularization, in a rabbit model without showing a notable side effect over current standard therapies. This platform could also be useful in treating other chronic ocular diseases. Painless and long-term sustained delivery of ocular drugs is enabled through the innovation of silicon nanoneedles.
