?METHODS:Two-hundred cases (400 eyes) was randomly separated into two groups: Group A included 200 eyes which corneal flaps were made by Z6, and Group B included rest of 200 eyes which corneal flaps were examined by a traditional Ziemer LDV CrystalLine femtosecond laser machine (CrystalLine). Visual acuity, slit lamp, refraction, Sim-K average, intraocular pressure (IOP), non-invasive tear break-up time (NIAvg-BUT), operation difficulty and complications were compared between two groups preoperatively and postoperatively.

?RESULTS:There was no significant differences between two groups in visual acuity, refraction, Sim-K average, IOP and NIAvg-BUT either preoperatively or 6mo postoperatively (P>0.05). Although there were significant differences in operation difficulty and complications were found between two groups (P<0.05), there was no serious complication in any group. Furthermore, a clear demarcation line could be observed in the cornea of Group A postoperatively.

?CONCLUSION:More careful and strict requirements are needed when using the new Z6 femtosecond laser for corneal flaps.

目的：評價新型Ziemer LDV Z6納焦飛秒激光機(簡稱“Z6飛秒”)制作角膜瓣的LASIK手術(shù)效果。

方法：隨機抽取我院2015-06/12飛秒制瓣LASIK手術(shù)患者200例400眼，其中Z6飛秒制瓣200眼(Z6組)，傳統(tǒng)Ziemer LDV CrystalLine納焦飛秒激光機(簡稱“CrystalLine飛秒”)制瓣200眼(CrystalLine組)。比較兩組患者在術(shù)前、術(shù)后不同時間的視力、屈光度、Sim-K平均值、裂隙燈表現(xiàn)、眼壓、非侵襲平均淚膜破裂時間(NIAvg-BUT)、手術(shù)操作難易度等方面的差異。

結(jié)果：兩組患者在術(shù)前和術(shù)后6mo時的視力、屈光度、Sim-K平均值、眼壓、NIAvg-BUT等方面無統(tǒng)計學差異(P>0.05)。Z6組的部分患者在術(shù)中掀瓣方面有一定難度，術(shù)中不透明氣泡層和不完全切割的發(fā)生率較高(P< 0.05)，但無嚴重并發(fā)癥發(fā)生。術(shù)后裂隙燈下觀察，Z6組患者角膜瓣邊界比CrystalLine組更容易辨認。

結(jié)論：新型Z6飛秒比傳統(tǒng)CrystalLine飛秒在術(shù)中角膜瓣處理方面的要求更為精細和嚴格，需要引起屈光手術(shù)醫(yī)師的重視。

0　引言

飛秒激光制作角膜瓣的LASIK手術(shù)已經(jīng)被越來越多的中國屈光手術(shù)醫(yī)師所使用。在諸多的飛秒激光手術(shù)設(shè)備中，瑞士Ziemer公司生產(chǎn)的LDV CrystalLine納焦飛秒激光機(簡稱“CrystalLine飛秒”)因為其激光速度快、切割面平滑度高、設(shè)備體積小巧、移動方便、激光頭活動靈活、基質(zhì)不透明氣泡層(OBL)輕、制瓣后無需等待即可掀瓣等諸多優(yōu)點，得到了廣大屈光手術(shù)醫(yī)師的青睞[1]。河北省眼科醫(yī)院屈光治療科應用CrystalLine飛秒已經(jīng)有6a的歷史[2]；2015-10醫(yī)院再次引進中國第一臺Ziemer LDV Z6納焦飛秒激光機(簡稱“Z6飛秒”)。Z6……
