Dr. Prausnitz says some people may find the microneedles uncomfortable despite their size.

普罗斯尼茨博士说，尽管这种微针头很细，也会有人觉得。

In their report, the researchers say the new technology has microneedle patches that administer a vaccine when pressed against the skin.

在他们的报告中，研究人员说，这项新技术有微针贴，当按压在肤上时，可以射疫苗。

The microneedles are either hollow or empty, like a normal hypodermic needle, or covered with a drug which breaks down in the eye.

这种微针头像普通的射针头一样是中空的，或者覆盖了一层在眼睛里分解的药物。

These instruments, called microneedles, can put medication into the front of the eye, exactly where it is needed.

称作微针头，可以把药物射到眼睛的前面，正好是需要治疗的位置。

Dr. Prausnitz says some people may find the microneedles uncomfortable despite their size. But he says an anesthetic drug could be used so that a patient does not feel any pain.

Prausnitz博士说，有些人可能会觉得微针，尽管它们的尺寸很小。但他表示，可以使用麻醉药物，使患者会感到任何疼痛。
