FS200飞秒与ZiemerLDV飞秒制瓣并发症对比分析

FS200 femtosecond and Ziemer LDV system of femtosecond flap complications

目的通过FS200与ZiemerLDV飞秒激光制作角膜瓣在术中术后并发症的对比分析，探讨两种不同能量的飞秒激光制作角膜瓣的特点，提高手术安全性。方法对2013年1月至2014年6月在石家庄爱尔眼科医院接受LASIK手术治疗近视患者，分为二个组：FS200飞秒激光组（A组）、ZiemerLDV飞秒激光组（B组），术中术后观察随访并发症进行对比分析。结果FS200与ZiemerLDV飞秒激光制瓣均未出现影响术后视力的并发症。术中并发症：角膜基质气泡、球结膜出血、切口出血、不全及不规则瓣、前房气泡两组对比差异具有统计学意义（P〈0．05），负压环脱失两组对比无统计学意义（P〉O．05），术中两组都未出现掀瓣困难；术后并发症：两组术后无一例出现角膜瓣中央坏死，Haze两组对比差异具有统计学意义（P〈0．05），角膜瓣微皱褶、一过性光敏反应、弥漫性层间角膜炎、虹视两组对比无统计学意义（P〉0．05）。结论FS200与ZiemerLDV飞秒激光由于激光脉冲的能量不同，屈光手术中制做角膜瓣并发症也不同，只要正确认识及时处理，它们都是安全可靠的。

Objective To analyze contrastively of corneal flap intraoperative complications using FS200 Ziemer LDV femtosecond laser, and to discusses two kinds of different energy of femtosec- ond laser making the characteristics of the corneal flap, and to improve operation safety. Methods The myopia patients from Shijiazhuang ophthalmic hospital undergoing LASIK surgery between Janu- ary 2013 and June 2014 was divided into two groups： FS200 femtosecond laser group （group A）, Ziemer LDV femtosecond laser group （group B）, postoperative observation of complications were ana- lyzed. Results By follow-up, FS200 and Ziemer LDV system of femtosecond laser disc did not ap- pear to affect postoperative vision. Intraoperative complications included comeal stroma bubbles, con- junctival hemorrhage, incomplete incision bleeding, and irregular lobe, anterior chamber bubble, there were differences statistical significance （P 〈0.05） compared the two groups. Negative pressure ring de- pigmentation compared the two groups had no statistical significance （P 〉0.05, see table 2）, in both groups there were no difficulty in lift valve; postoperative complications： two groups of postopera- tive had no central corneal flap necrosis. Haze difference compared the two groups had statistical sig- nificance （P 〈0.05, see table 3）. After corneal flap folds, photosensitive reaction, diffuse interlayer keratitis, rainbow compared the two groups had no statistical significance （P 〉0.05, see table 3）. Conclusions FS200 and Ziemer LDV femtosecond laser differ as a result of laser pulse energy, mak- ing corneal flap complications are also different in refractive surgery, as long as the correct under- standing of and timely treatment, they are both safe and reliable.
