目的: 观察分析并比较飞秒激光小切口角膜基质透镜取出术(SMILE)、飞秒激光制瓣的准分子激光原位角膜磨镶术(FS-LASIK)、经上皮的准分子激光屈光性角膜切削术(TPRK)术后6个月内高阶像差的变化、差异及影响因素。方法: 前瞻性非随机临床研究。连续选取2020年7月至2021年6月在温州医科大学附属眼视光医院屈光手术临床中心行SMILE、FS-LASIK、TPRK的近视或近视伴散光患者55例(55眼), 均纳入右眼, 根据手术方式不同分为SMILE组16眼、FS-LASIK组19眼、TPRK组20眼。除常规检查外, 术前及术后1、3、6个月测量波前像差, 从Pentacam眼前节分析仪中获取角膜前表面Q值及中央角膜厚度(CCT), 根据术前和术后CCT的差值获得实际基质切削深度, 采用切线差异法获得有效光学区直径。3组间术前基线数据、术后Q值和CCT等比较采用单因素方差分析;3组间像差比较采用双因素重复测量方差分析, LSD-t检验用于组内和组间的进一步比较;术后像差与各影响因素的相关关系采用Pearson相关性分析。结果: 在组内, 3组术后各随访时间点角膜总高阶像差(HOAs)、球差、彗差均较术前明显增大(均P<0.05);FS-LASIK组内术后3、6个月及TPRK组内术后各随访时间点全眼HOAs均较术前明显增大(均P<0.05), FS-LASIK组、TPRK组术后全眼球差均较术前明显增大(均P<0.001);SMILE组和FS-LASIK组术后眼内HOAs、TPRK组术后眼内球差、SMILE组术后眼内彗差、FS-LASIK组术后眼内三叶草像差均较术前明显减小(均P<0.05)。在组间, FS-LASIK组术后1个月的角膜球差明显大于SMILE组(P=0.013), FS-LASIK组和TPRK组术后3、6个月的角膜球差均明显大于SMILE组(均P<0.05)。SMILE组的有效光学区直径明显大于FS-LASIK组和TPRK组(均P<0.05), SMILE组角膜中央6 mm的Q值明显小于FS-LASIK组和TPRK组(均P<0.05)。3组的有效光学区直径与全眼球差、角膜HOAs、球差均呈负相关(均P<0.05);实际切削深度、Q值与角膜HOAs、球差均呈正相关(均P<0.05);等效球镜度的绝对值与全眼球差、角膜HOAs、球差均呈正相关(均P<0.05);术后CCT与角膜球差均呈负相关(均P<0.05)。结论: SMILE、FS-LASIK和TPRK术后角膜的高阶像差增大, 以球差和彗差为主, 其中SMILE术后诱导的球差较少。3种术式术后高阶像差的诱导与有效光学区直径、角膜厚度、非球面性、切削深度和屈光矫正量有关。

The accurate performance evaluation of a cutterhead is essential to improving cutterhead structure design and predicting project cost. Through extensive research, this paper evaluates the performance of a tunnel boring machine(TBM) cutterhead for cutting ability and slagging ability. This paper propose cutting efficiency, stability, and continuity of slagging as the evaluation indexes of comprehensive cutterhead performance. On the basis of research of true TBM engineering applications, this paper proposes a calculation method for each index. A slagging efficiency index with a ratio of the maximum di erence between the slagging amount and average slagging is established. And a slagging stability index with a ratio of the maximum slagging fluctuation and average slagging is presented. Meanwhile, a cutting efficiency index by the weighed average value of multistage rock fragmentation of a cutter’s specific energy is established. The Robbins and China Railway Construction Corporation(CRCC) cutterheads are evaluated. The results show that under the same thrust and torque, the slagging stability of the CRCC scheme is worse, but the slagging continuity of the CRCC scheme is better. The cutting ability index shows that the CRCC cutterhead is more efficient.
