Treating wounds on a part of the body as delicate as the eyeball isn't easy, but scientists have developed an innovative new approach: a therapeutic contact lens that can act as a bandage for damaged eyes.

要处理人体中像眼球这样脆弱部位上的伤口绝非易事，不过科学家已研发出一种创新疗法：治疗用隐形眼镜，它对受伤的眼睛来说相当于创可贴。

This is no ordinary contact lens, because it's made up of donor cells left over from regular corneal transplants.

这不是普通的隐形眼镜，因为它由常规角膜移植遗留下来的供体细胞组成。

These special limbal mesenchymal stromal cells help to encourage the injured eye to repair its wounds itself.

这些特殊的角膜缘间充质间质细胞有助于刺激受创眼部进行自我修复。

According to the researchers, a contact lens bandage could be in place within hours of a patient arriving at hospital with eye damage.

研究人员称，眼部受伤的患者到医院数小时内，就能用上隐形眼镜创可贴。

It's likely to be cheaper and easier to apply than current treatments too.

这种方法可能比现有疗法更便宜、更易应用。

"Based upon preliminary data we believe that the donor cells release a range of wound-healing factors that encourage repair of the eye's surface," says one of the researchers, Damien Harkin from the Queensland University of Technology (QUT) in Australia.
