世界上每年都有几十万近视患者通过外科医生的手术刀恢复正常视力,但是这种角膜外科手术不久将被激光系统代替,这种屈光角膜手术(PRK)利用蓝光准分子激光器使眼睛恢复正常视力,PRK利用一束准分子激光切除眼球前面大约半根头发丝那么厚的角膜,从而改变眼球的形状使患者恢复正常视力。这种手术普通医院的眼科医生都能做。 Every year in the world hundreds of thousands of myopic patients return to normal vision with a surgeon’s scalpel, but this type of corneal surgery is soon to be replaced by a laser system. This refractive corneal surgery (PRK) uses a blue excimer laser to restore the eye Normal vision, PRK uses a bunch of excimer laser in front of the eye cut about half the thickness of the hair of the cornea, thus changing the shape of the eye so that patients return to normal vision. Ophthalmologists in this surgery can do it.
