If we wear corrective lenses now , perhaps our vision could be improved or restored through laser surgery . we would no longer need to wear glasses 如果我们现在带上矫正镜，或通过激光手术我们的视力就会改善或恢复。我们将不再需要带眼镜了。
This paper reports the different laser operation methods . the treatment results are generally satisfactory . the complication after laser therapy and prognosis were discussed 报道了不同的激光手术，治疗效果通常满意，并对激光手术后并发症及治疗作了讨论。
No , only vitrectomy can remove floaters . yag and other lasers have been used to treat floaters but there is no scientific evidence that laser treatment is safe or effective 没有。只有玻璃体切除术可以消除飞蚊， yag和其他的激光手术都曾经应用于除蚊，但目前还没有科学依据证明激光治疗的方法是安全，可靠的。

Lasik is performed as an outpatient procedure . no injections are needed . patients remain awake and the procedure is carried out using anaesthetic eyedrops . the entire lasik procedure takes about 10 - 15 minutes 准分子激光手术就如一项为门诊病人诊断的过程。无需注射任何药物。即使在手术过程中使用麻醉眼滴，病人仍然保持清醒。整个准分子激光手术过程只需费时10至15分钟。
The lasers used in surgeries , such as ocular surgery , dental surgery , dermatic surgery and medical surgery , are because their functional thermal ablation and melting ablation . meanwhile , the biomodulation of low intensity laser irradiation was found in many years ago . however there is still little of study focusing on the intersection of the two fields 随着激光研究理论和生产技术的不断发展，不但高强度激光手术在外科、眼科、牙科和皮肤科等领域获得了越来越为广泛的应用，而且低强度激光的光生物调节作用研究也已经获得相当的进展，但很少有人注意到两个领域的交叉。
Another approach to performing excimer laser surgery without cutting a corneal flap is the use of a diluted alcohol solution to weaken the attachment between the most superficial layer of the cornea - the epithelium , and the rest of the corneal tissue - to allow laser ablation 另外还有一种无需切割角膜的准分子激光手术，称为角膜上皮切割激光矫视手术( lasek ) ，方法是使用经过稀释的酒精软化角膜上层(即上皮)与角膜下层组织相连的部份，从而掀起瓣膜进行激光治疗。
In fact , the intensity of high power laser beem decreases rapidly when laser is transmissing in bio - tissue and the intensity of the edge of laser beem is so low that photobiomodulation , which might effect the healing process after laser surgery , but not thermal effect might work . in this thesis , monolayer human skin fibroblasts was used as models to study the damage effect of high intensity laser irradiation and photobiomodulation of marginal irradiation of high intensity laser beam 高强度激光在生物组织中迅速衰减，激光束边缘强度低到无法损伤细胞，这部分激光对已损伤组织边缘存活细胞的光生物调节作用(例如，对细胞增殖的促进或抑制效应，对免疫细胞功能的调节)是决定高强度激光手术后生物修复状况的主要因素之一。
The coupling issues with optical fibers are often deal with in many application fields of high - power ld , such as the light sources and pumping sources of optical fiber amplifiers in optical fiber communications systems , laser surgery operation in medicine , laser welding and heat processing in materials mechanical process and so on 大功率ld的许多应用领域和应用场合都涉及到与光纤的耦合,比如光通信系统中的光源和光纤放大器的泵浦源,医疗方面的激光手术,材料加工方面的焊接和热处理等等。
