新型滴眼液將讓你不用再戴眼鏡英語(yǔ)美文
Researchers from the Shaare Zedek Medical Center and Bar-Ilan University just released a report explaining how a new type of eye drop infused with “nanoparticles” could replace the need for glasses or contacts. It’s a bit complicated and requires a brief doctor visit, but it apparently works like a charm.
來(lái)自沙爾澤戴克醫(yī)學(xué)中心和巴伊蘭大學(xué)的研究人員剛剛發(fā)表了一份報(bào)告，解釋了一種注入“納米粒子”的新型滴眼液將如何替代框架眼鏡或隱形眼鏡。過(guò)程有點(diǎn)復(fù)雜，需要經(jīng)過(guò)醫(yī)生的簡(jiǎn)單診斷，但效果十分驚人。
The three-step process starts with a measurement of the individual’s eye refraction, which can be performed with a smartphone. Then, doctors create a very specific laser pattern which is applied to the eye for less than one second. The laser creates tiny grooves in the surface of the cornea. Lastly, special eye drops are applied.
分三個(gè)步驟， 首先是測(cè)量個(gè)人的眼球屈光度，可用智能手機(jī)完成。然后，醫(yī)生創(chuàng)造出一種非常特殊的激光圖案，在眼球上照射不到一秒的'時(shí)間。激光在角膜表面產(chǎn)生微小的凹槽。最后，使用特殊滴眼液。
“These nanoparticles go into the shallow ablated patterns generated on the surface of the cornea,” Zeev Zalevsky explained to Digital Trends. “They change the refraction index inside of those patterns. This corrects the visual problem the user has. The process of correction can be done at home without the need of a medical doctor.”
“這些納米粒子進(jìn)入角膜表面形成的淺凹槽內(nèi)，” 澤夫.扎勒夫斯基向《數(shù)字趨勢(shì)》解釋道，“改變凹槽內(nèi)的折射率。矯正使用者的視力。矯正過(guò)程可以在家里完成，不需要醫(yī)生�！�
The procedure is less invasive than traditional laser eye surgery in that it only affects the exterior of the eye and does not require an extensive procedure. However, because the alterations to the eye are so minor, the tiny etchings in the cornea eventually heal themselves and vision subsequently degrades. The researchers believe the positive effects of the treatment will last one to two months.
該手術(shù)相比傳統(tǒng)的眼科激光手術(shù)創(chuàng)傷更小，因?yàn)樗桓淖冄矍虮砻�，沒(méi)有深入的過(guò)程。但是，由于這種方法對(duì)角膜造成的創(chuàng)傷極小，所以角膜的微小凹槽最終會(huì)自行愈合，視力也會(huì)隨之退化。研究人員認(rèn)為這種治療的積極效果將持續(xù)一到兩個(gè)月。
Heading to the eye doctor for a reapplication of the laser every two months sounds pretty inconvenient, but the technology is still in its infancy. Going forward, the researchers are planning additional testing and hope to have something resembling a commercial product available within the next two years.
每?jī)蓚�(gè)月就要看一次眼科醫(yī)生，申請(qǐng)一次新的激光治療聽(tīng)起來(lái)很不方便，但是這項(xiàng)技術(shù)還處于初始階段。展望未來(lái)，研究人員正計(jì)劃進(jìn)行其他測(cè)試，希望在未來(lái)兩年內(nèi)推出類(lèi)似的商業(yè)產(chǎn)品。
