Abstract

In the advent of an increasingly aging population and due to the popularity of electronic devices, ocular conditions have become more prevalent. In the world of medicine, accomplishing eye medication administration has always been a difficult task. Despite the fact that there are many commercial eye drops, most of them have important limitations, due to quick clearance mechanisms and ocular barrers. One solution with tremendous potential is the contact lens used as a medication delivery vehicle to bypass this constraint. Therapeutic contact lenses for ocular medication delivery have attracted a lot of attention because they have the potential to improve ocular bioavailability and patient compliance, both with minimal side effects. However, it is essential not to compromise essential features such as water content, optical transparency, and modulus to attain positive in vitro and in vivo outcomes with respect to a sustained drug delivery profile from impregnated contact lenses. Aside from difficulties like drug stability and burst release, the changing of lens physico-chemical features caused by therapeutic or non-therapeutic components can limit the commercialization potential of pharmaceutical-loaded lenses. Research has progressed towards bioinspired techniques and smart materials, to improve the efficacy of drug-eluting contact lenses. The bioinspired method uses polymeric materials, and a specialized molecule-recognition technique called molecular imprinting or a stimuli-responsive system to improve biocompatibility and support the drug delivery efficacy of drug-eluting contact lenses. This review encompasses strategies of material design, lens manufacturing and drug impregnation under the current auspices of ophthalmic therapies and projects an outlook onto future opportunities in the field of eye condition management by means of an active principle-eluting contact lens.

摘要

随着人口老龄化加剧以及电子设备的普及,眼部疾病愈发普遍。在医学领域,眼部药物给药一直是一项艰巨的任务。尽管有许多市售眼药水,但由于快速清除机制和眼部屏障,它们大多存在重要局限性。一种具有巨大潜力的解决方案是将隐形眼镜用作药物递送载体以绕过这一限制。用于眼部药物递送的治疗性隐形眼镜备受关注,因为它们有可能提高眼部生物利用度和患者依从性,且副作用最小。然而,为了从浸渍隐形眼镜获得关于持续药物递送曲线的积极体外和体内结果,至关重要的是不能损害诸如含水量、光学透明度和模量等基本特性。除了药物稳定性和突释等困难外,治疗性或非治疗性成分引起的镜片物理化学特性变化可能会限制载药镜片的商业化潜力。研究已朝着仿生技术和智能材料发展,以提高药物洗脱隐形眼镜的疗效。仿生方法使用聚合材料以及一种称为分子印迹的特殊分子识别技术或刺激响应系统来提高生物相容性并支持药物洗脱隐形眼镜的药物递送功效。本综述涵盖了在当前眼科治疗背景下的材料设计、镜片制造和药物浸渍策略,并通过活性成分洗脱隐形眼镜对眼部疾病管理领域的未来机遇进行了展望。
