abbr.准分子激光角膜切削术(PhotorefractiveKeratectomy);朝鲜(PeoplesRepublicofKorea)
1、The technique of photorefractive keratectomy (PRK) represents a major development in ophthalmology.───技术屈光性角膜切削术(PRK治疗)是一项重大的发展在眼科。
2、PRK has become less common in recent years because more eye surgeons prefer the LASIK procedure.───近几年PRK变得不太普遍了,更多的眼科手术喜欢选用术后好预测的LASIK程序。
3、It avoids all flap-related complications associated with LASIK, and has less postoperative pain and faster recovery than PRK.───此手术避免了LASIK手术与角膜瓣相关的并发症,同PRK相比,术后回退发生率更低恢复更快。
4、In general, for correcting nearsightedness over 3 diopters, both LASIK and PRK are better than radial keratotomy (RK).───在一般情况下,对于纠正300度以上的近视来说,LASIK和PRK手术两者均优于RK(径向角膜切开术)手术。
5、the top layer of the cornea, called the epithelium, is scraped away to expose the stromal layer underneat.───角膜切削术使用的方法是削去角膜的顶层,又称上皮层,来显露下面的基质层。
6、There is no agreement about whether LASIK is superior to PRK or vice versa for people with mild to moderate nearsightedness.───但是对于轻度至中度近视患者来说,在LASIK手术是否优于PRK手术这一问题上却仍无定论。
7、It may take three to six months before your vision improves completely. Most people undergoing PRK have both eyes done on the same day.───你的视力完全改善则需要三到六个月,选择PRK手术的大多数人同一天做两只眼睛。
8、Currently PRK can only be used to correct myopia and astigmatism, but hypermetropia may also be corrected by PRK in the near future.───目前手术只能用于纠正近视及散光,但也可能是远视矫正手术在不久的将来。

近视治疗一般有三种方法。一种是佩戴框架眼镜,一种是佩戴隐形眼镜,一种就是进行近视的屈光手术治疗,其中最常用的是近视的激光手术治疗。近视激光手术现在常用的有两种,一种是传统激光,一种是飞秒激光。所谓半飞秒激光手术,就是结合了这两者方法,在手术的前半段用飞秒激光进行角膜瓣的切削,制作角膜瓣,然后在手术的后半程用常规的激光来进行手术,建议去正规专科的医院
