中新网广州1月10日电(记者 杨薇)中山大学中山眼科中心10日召开发布会，宣布蔡司VisuMax全飞秒系统将进驻该眼科中心，这也是华南地区首家拥有这一屈光手术系统的公立医院，对近视患者来说，又多了一种新的手术选择。

Beijing on January 10, guangzhou(Reporter YangWei)Zhongshan ophthalmic center, sun yat-sen university held a conference 10 days,CaiSi announced VisuMax full femtosecond system will enter the eye center,This is also the first in south China with the refractive surgery system of public hospital,For patients to myopia,And a kind of new operation choice.

　　在10日召开的发布会上，也吸引了来自中国不同医院知名眼科专家对全飞秒激光技术进行了研讨和推介。

In the ten days at the conference,Also attracted from China different hospital famous eye doctor to the femtosecond laser technology research and promotion.

　　虽然制作角膜瓣和准分子激光消融屈光度数的经典手术方式已经非常成熟，但角膜瓣的存在始终是这种手术方式的弊端，切断角膜神经引起的眼表干燥和生物力学改变、碰撞容易引起角膜瓣皱褶或移位，这些都是手术的潜在风险。

Although making corneal flap and quasi molecular laser ablation diopter several classic operation mode has been very mature,But the presence of corneal flap is always the operation method of disadvantages,Cut off the corneal nerve cause eye table dry and biomechanical changes/Collision easy to cause corneal flap folds or shift,These are the potential risks of surgery.

　　据中山大学中山眼科中心激光近视眼治疗中心主任刘泉教授介绍，飞秒激光是一种超短脉冲形式，波长为1053nm的一种近红外激光，其能通过物理作用分离角膜组织。飞秒激光脉冲持续时间极短，周期为飞秒级，飞秒是一种时间计量单位，1飞秒只有1秒的一千万亿分之一。由于极短的脉冲持续时间，飞秒激光具有非常高的瞬时功率，可在透明组织内任意位置进行精确聚焦切割，可以完成微米级的精细手术，而且对切割区以外的组织影响小，故具有极高的安全性。近年来它被逐渐应用到眼科领域，是一种全新的眼科手术手段。

According to sun yat-sen university zhongshan ophthalmic center laser myopic eye treatment center director professor LiuQuan is introduced,Femtosecond laser is a kind of ultrashort pulse form,Wavelength of 1053 nm of a kind of near infrared laser,It can through the physical function separation corneal tissue.Femtosecond laser pulse duration is very short,Cycle for FeiMiaoJi,Femtosecond is a time unit of measurement,1 femtosecond only 1 seconds of one over one quadrillion.Because of a very short pulse duration,Femtosecond laser has very high instantaneous power,Can be in transparent organization at any position within the precise focus cutting,Can complete micron grade fine surgery,And for cutting area outside of the organization affect little,It has high security.In recent years it has been gradually applied to the field of ophthalmology,Is a new means of eye surgery.

　　全飞秒激光小切口微透镜取出术于2011年在全球上市，这种全新的手术方式比起准分子激光手术来说彻底摒弃了角膜瓣存在的必要性，仅在角膜上方做一个约4mm大小的浅层切口就可以将飞秒激光制作的精确的拟矫度数透镜取出，真正实现了无刀、无瓣。

All the femtosecond laser micro lens small incision was removed in 2011 in global listed,This new operation method compared with quasi molecular laser surgery is completely abandoned the necessity of corneal flap,Only in the cornea a about 4 mm size of shallow incision can femtosecond laser made accurate fitting degree lens out monitoring,No true knife/No disc.

　　刘泉强调，这一手术方式对手术医生的要求更高，但术中的精确性和术后的安全性大大提高，从目前随访情况来看，视力恢复情况良好，没有了角膜瓣的风险，患者术后视觉质量更好，生物力学改变少，眼睛不怕碰撞，眼干的症状也大大改善，也适应于如武警、拳击运动员等特殊行业的人群。

LiuQuan emphasize,The operation mode of operation of the higher request,But the operation accuracy and postoperative safety greatly improved,Follow-up from the current situation,Visual acuity in good condition,Without the risk of corneal flap,Patients postoperative visual quality is better,Biomechanical change little,Eyes are not afraid of collision,Dry eye symptoms also greatly improved,Also adapted to such as armed police/Boxing athletes and other special industry crowd.

　　从今年起，中山眼科中心将引进该技术，手术适用范围以18岁以上的400至800度的中高度近视或散光患者为最佳。目前，中国已有5000多个成功案例，该手术定价约2万4千元不等。(完)

From this year,Zhongshan ophthalmic center will introduce the technology,The operation scope to eighteen years 400 to 800 degrees in high myopia and astigmatism patients is the best.At present,China has more than 5000 successful cases,The operation pricing of about 24000 dollars.(finish)
