目的：评估FS-LASIK手术在制作角膜瓣过程中不透明气泡层(OBL)的发生对准分子激光机眼球旋转追踪补偿的影响。
方法：前瞻性临床研究。随机抽取2019-07/09在我院行FS-LASIK手术200例400眼。统计FS-LASIK术中OBL的总体发生率、角膜瓣外OBL发生率、角膜瓣内OBL发生率、动态自旋跟踪矫正(DCC)和静态自旋追踪矫正(SCC)的运行成功率，并分析OBL对DCC和SCC运行的影响。
结果：本研究共发生OBL 183眼，总体OBL发生率为45.8%， DCC成功运行397眼，总体DCC运行成功率为99.2%； SCC成功运行的手术共计为293眼，总体SCC运行成功率为73.2%； 总体OBL、角膜瓣外OBL、角膜瓣内OBL对DCC的运行成败均无影响(P>0.05)，但对SCC的运行成败均有影响(P<0.05)，OBL发生会导致SCC运行失败。
结论：在制作角膜瓣过程中OBL的发生可能会导致FS-LASIK准分子激光机SCC运行的失败。

[Abstract]
AIM: To evaluate the effect of opaque bubble layer(OBL)on the ocular cylotorsion compensation during FS-LASIK procedures.
METHODS: Prospectively clinical study. From July 2019 to September 2019, two-hundred FS-LASIK patients(400 eyes)were randomly included into this study. The total OBL incidence, flap-out OBL incidence, flap-in OBL incidence, incidence of dynamic cyclotorsion component(DCC)and incidence of static cyclotorsion component(SCC)were statistically analyzed.
RESULTS: OBL developed in 183 eyes of 400 FS-LASIK eyes, with a total OBL incidence of 45.8%. DCC was successfully performed on 397 eyes, with a total DCC incidence of 99.2%. SCC was successfully performed on 293 eyes, with a total SCC incidence of 73.2%. Neither flap-out OBL nor flap-in OBL could disturb the successful implementation of DCC during the operation(P>0.05). Both flap-out OBL and flap-in OBL could impact the SCC implementation and make it fail(P<0.05).
CONCLUSION: OBL can result in failure of SCC implementation during the FS-LASIK procedures.
