目的:探讨VisuMax飞秒激光制作超薄角膜瓣LASIK术的临床疗效。
方法:患者120例240眼采用VisuMax飞秒激光系统制作90~100μm角膜瓣联合MEL80准分子激光系统切削角膜,观察术后效果和并发症。
结果:术后第1d,裸眼视力达到术前最佳矫正视力198眼(82.5%); 术后1wk达术前最佳矫正视力236眼(98.3%); 1mo后141眼(58.75%)超过术前最佳矫正视力1行以上。所有患者无明显并发症。
结论:飞秒激光制作超薄角膜瓣是一种安全、准确的方法,它与LASIK术的结合是个性化角膜屈光手术的完善,值得临床推广。

[Abstract]
AIM: To research the efficacy of LASIK ultra-thin corneal flap created with VisuMax femtosecond laser.
METHODS: Femtosecond laser LASIK was performed for 120 patients(240 eyes)with VisuMax femtosecond laser system in the production of 90-100μm corneal flap and MEL80 excimer laser corneal ablation. Then postoperative results and complications were observed.
RESULTS: The postoperative uncorrected visual acuity(UCVA)reached preoperative best-corrected visual acuity(BCVA)in 198 eyes(82.5%)one day after operation, in 236 eyes(98.3%)after 1 week of operation. And the postoperative UCVA exceeded preoperative BCVA in 141 eyes(58.75%)after 1 month of operation. No serious postoperative complications were observed in all cases.
CONCLUSION: LASIK combined with ultra-thin corneal flap created by VisuMax femtosecond laser is safe and accurate, which makes individualized corneal refractive operation more perfect.
