After 2001, the femtosecond laser is approved for use in LASIK surgeries in the US.

2001年后，飞秒激光获准在美国用于LASIK手术。

But increasingly, femtosecond lasers are being used for both parts of the procedure.

但越来越多地，飞秒激光被用于手术两个环节。

This left only a slim window – a few femtoseconds – where the laser  was reflected.

这只留下了一个很口（几飞秒），激光被反射。

Femtosecond technology is also transforming how surgeons deal with cataracts, cloudy patches that develop on the lens of an eye, resulting in impaired vision.

飞秒技术正在改变外科医生理白内障方式，这些白内障是在眼睛晶状体上形成云状，致视力受损。

In femtosecond laser-assisted cataract surgery, a laser makes tiny incisions in the cornea and then a circular opening in the front of the capsule that surrounds the lens.

在飞秒激光辅助白内障手术中，激光会在角膜上制造微切口， 然后在包裹晶状体囊前部制造一个圆形开口。

But it was the development of femtosecond laser technology in 1995-97 by American biomedical engineers Tibor Juhasz and Ron Kurtz that made laser eye surgery safer, more precise and more predictable.

然而，正是1995年至1997年间，美国生物医学工程师蒂博尔·尤哈斯和罗恩·库尔茨开发出飞秒激光技术，使得激光眼科手术变得更加安全、精准且可预测。

Katherine strode briskly into the main lab. The bright and sterile work space glistened with advanced quantitative equipment: paired electro encephalographs, a femtosecond comb, a magneto-optical trap, and quantum-indeterminate electronic noise REGs, more simply known as Random Event Generators.

Katherine快步走进主实验室。明亮而无菌工作空间闪闪发光，配备了先进定量设备：成对脑电图、飞秒梳、磁光阱和量子不确定电子噪声 REG，更简单地称为随机事件发生器。
