目的：探讨FS200飞秒激光制作个性化角膜瓣的临床疗效、安全性、厚度范围及操作要点。
<br> 方法：采用FS200飞秒激光系统制作个性化角膜瓣815例1620眼,术中测量角膜瓣厚度,观察总结术中及术后角膜瓣的并发症。
<br> 结果：术后1 d；1 wk达到或超过最佳矫正视力分别占总数98.16%和100%；术后1 d；1 wk等效球镜度数±0.50 D内分别占总数97.55%和98.16%；术后1 d；1 wk等效球镜度数±1.00 D内分别占总数99.39%和100%；术中测量实际角膜瓣厚度值与预设值有统计学差异(P<0.05)；发生球结膜下出血70例80眼(4.94%),角膜瓣下气泡40例40眼(2.47%),前房气泡2例2眼(0.12%),隧道出血20例40眼(2.47%),角膜瓣出血1例2眼(0.12%),瓣边缘小片未切区3例3眼(0.19%),边切较不规整及偏位10例10眼(0.62%),负压环脱环1例1眼(0.06%),改期手术7例8眼(0.49%)。
<br> 结论：FS200飞秒激光制瓣安全性高、舒适度好、并发症少。术者操作技术熟练、患者角膜上皮正常及配合度好情况下,FS200飞秒激光可制作薄至90 mm的角膜瓣。

<br> 方法：採用FS200飛秒激光繫統製作箇性化角膜瓣815例1620眼,術中測量角膜瓣厚度,觀察總結術中及術後角膜瓣的併髮癥。
<br> 結果：術後1 d；1 wk達到或超過最佳矯正視力分彆佔總數98.16%和100%；術後1 d；1 wk等效毬鏡度數±0.50 D內分彆佔總數97.55%和98.16%；術後1 d；1 wk等效毬鏡度數±1.00 D內分彆佔總數99.39%和100%；術中測量實際角膜瓣厚度值與預設值有統計學差異(P<0.05)；髮生毬結膜下齣血70例80眼(4.94%),角膜瓣下氣泡40例40眼(2.47%),前房氣泡2例2眼(0.12%),隧道齣血20例40眼(2.47%),角膜瓣齣血1例2眼(0.12%),瓣邊緣小片未切區3例3眼(0.19%),邊切較不規整及偏位10例10眼(0.62%),負壓環脫環1例1眼(0.06%),改期手術7例8眼(0.49%)。
<br> 結論：FS200飛秒激光製瓣安全性高、舒適度好、併髮癥少。術者操作技術熟練、患者角膜上皮正常及配閤度好情況下,FS200飛秒激光可製作薄至90 mm的角膜瓣。

AIM: To discuss the clinical efficacy, the safety, the thickness range and operating key points of LASIK personal corneal flap made by FS200 femtosecond laser machine.
<br> METHODS: A total of 1 620 eyes of 815 patients underwent LASIK with flaps created by wavelight FS200 femtosecond laser were involved. Corneal flaps thickness in operation was measured, the intraoperative and postoperative complications were observed and summarized.
<br> RESULTS: 98. 16% the uncorrected visual acuity ( UCVA ) postoperation 1d and 100% the UCVA postoperation 1wk reached the best corrected visual acuity preoperation or above; 97. 55% of spherical equivalent refractions postoperation 1d and 98. 16% of spherical equivalent refractions postoperation 1 wk were within± 0.50D; 99. 39% of spherical equivalent refractions postoperation 1d and 100% of spherical equivalent refractions postoperation 1wk were within ±1. 00D; There were difference of corneal flaps thickness between measured value and preset value (P<0. 05);80 eyes of 70 patients had subconjunctival hemorrhage ( 4. 94%), 40 eyes of 40 patients had bubbles under flap (2. 47%), 2 eyes of 2 patients had anterior chamber bubbles (0.12%), 40 eyes of 20 patients bleed in canal (2. 47%), 2 eyes of 1 patient bleed in corneal margin (0. 12%), 3 eyes of 3 patients had flaps with an marginal uncut area ( 0.19%) , 10 eyes of 10 patients had flaps with an irregular and dislocated margin (0. 62%), 1 eye of 1 patient had suction loss during the operation (0. 06%), 8 eyes of 7 patients postponed operation (0. 49%).
<br> CONCLUSION: FS200 femtosecond laser is safe, comfortable and little complications in the production of LASIK flaps. If the surgeon operate expertly, patients cooperate well and have healthy cornea epithelium, FS200 femtosecond laser can make ultra-thin corneal flap of 90 m m safely.
