最新納米顆粒滴眼液 竟可替代眼鏡和隱形眼鏡?

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.

來自沙爾澤戴克醫學中心和巴伊蘭大學的研究人員剛剛發表了一份報告，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。

It's a bit complicated and requires a brief doctor visit, but it apparently works like a charm.

過程有點複雜，需要經過醫生的簡單診斷，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.

這一過程共分三個步驟，首先是測量個人的眼球屈光度，可用智能手機完成。

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.

然後，醫生創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間。激光在角膜表面產生微小的凹槽。最後，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.

澤夫·扎勒夫斯基向《數字趨勢》解釋道：“這些納米粒子進入角膜表面形成的淺凹槽內。”

"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."

“它們會改變凹槽內的折射率。矯正使用者的視力。矯正過程可以在家裏完成，不需要醫生。”

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.

該手術相比傳統的眼科激光手術創傷更小，因爲它只改變眼球表面，沒有深入的過程。

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.

但是，由於這種方法對角膜造成的創傷極小，所以角膜的微小凹槽最終會自行癒合，視力也會隨之退化。研究人員認爲這種治療的積極效果將持續一到兩個月。

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.

每兩個月就要看一次眼科醫生，申請一次新的激光治療聽起來很不方便，但是這項技術還處於初始階段。

Going forward, the researchers are planning additional testing and hope to have something resembling a commercial product available within the next two years.

展望未來，研究人員正計劃進行其他測試，希望在未來兩年內推出類似的商業產品。
