目的：比较不同预设光学区组的飞秒激光小切口基质透镜取出术(small incision lenticule extraction，SMILE)和飞秒激光制瓣联合准分子激光原位角膜磨镶术(femtosecond laser-assisted in situ keratomileuses，FS-LASIK)术后有效光学区(effective optical zone，EOZ)大小与角膜高阶像差(high order aberrations，HOAs)变化以及有效光学区大小对角膜高阶像差的影响。方法：收集2019年2月 至2020年5月来佛山市第二人民医院行激光手术的患者80例，均取右眼入组，SMILE组43例，FSLASIK组37例，按预设光学区大小分为6.5 mm和6.0 mm组，分别于术前和术后1个月应用Pentacam三维眼前节分析系统测量有效光学区及总角膜高阶像差、彗差、球差，分析不同预设光学区下SMILE组和FS-LASIK组有效光学大小及与角膜高阶像差的关系。结果：在相同预设光学区下，术后1个月SMILE组的有效光学区均大于FS-LASIK组，差异均有统计学意义(均P<0.05)，且SMILE组的角膜总高阶像差、球差、彗差均较FS-LASIK组低，差异均有统计学意义(均P<0.05)；对于相同手术方式，预设光学区6.0 mm较6.5 mm组，术后1个月角膜总高阶像差、球差、彗差均升高，差异均有统计学意义(均P<0.05)。结论：SMILE组和FS-LASIK组术后1个月的有效光学区均小于预设光学区，SMILE组大于FS-LASIK组；术后1个月有效光学区越大，角膜高阶像差越小；在相同预设光学区下，SMILE组术后1个月角膜高阶像差小于FS-LASIK组。

Objective: To compare the effective optical zone (EOZ) and the changes in corneal high order aberrations (HOAs) after small incision lenticule extraction (SMILE) with those after femtosecond laser-assisted in situ keratomileuses (FS-LASIK). Methods: This study included 80 subjects who underwent laser refractive surgery at the Second People’s Hospital of Foshan between February 2019 and May 2020. Only data from the right eye of each subject were analyzed. A total of 43 eyes underwent SMILE while 37 eyes received FS-LASIK. The eyes were further stratified into subgroups based on different programmed optical zones: the 6.5 mm group and the 6.0 mm group. EOZ, coma, and spherical aberration were measured with Pentacam 3D anterior segment analysis system preoperatively and one month postoperatively. In addition, the relationship between EOZ and corneal HOAs was analyzed and compared between different optical-zone groups after SMILE and FS-LASIK. Results: For the same programmed optical zone, the SMILE group achieved a significantly greater EOZ than the FS-LASIK group who was measured 1-month postoperatively did (P<0.05). Meanwhile, corneal HOAs, spherical aberration, and coma in the SMILE group are significantly lower than those in the FS-LASIK group (P<0.05). For the same procedure (SMILE or FS-LASIK), the 6.0 mm group demonstrated significantly higher corneal total HOAs, spherical aberration, and coma than the 6.5 mm group did 1-month after the surgery (P<0.05). Conclusion: In both the SMILE and the FS-LASIK groups, 1-month postoperative EOZ was smaller than the programmed optical zone. EOZ in the SMILE group was larger than that in the FS-LASIK group. The larger the 1-month postoperative EOZ was, the lower corneal HOAs were. For the same programmed optical zone, 1-month postoperative corneal HOAs in the SMILE group is lower than that in the FS-LASIK group.

目的：探讨飞秒激光辅助角膜内皮移植(endothelial keratoplasty，EK)患者的护理。方法：对40例 行飞秒激光辅助EK术的患者做好术前心理护理，完善术前检查及术前准备，术后重点做好体位护 理、病情观察及出院指导。结果：4例患者术后发生植片移位，经再次复位后贴合良好，1例术后第1天气泡到后房行前房成形术；13例患者术后出现眼压升高，经治疗眼压得到控制；40例患者全 部治愈出院。结论：对EK术患者应做好术前及术后的护理，及时发现并发症并采取相应的治疗与护理措施，以提高手术的成功率。

Objective: To explore the nursing care of patients with femtosecond laser assisted endothelial transplantation. Methods: Forty patients were involved in this study. Preoperative psychological nursing, ocular examination, and surgical preparation were taken, and the main nursing postoperation focused on patients’ position and the discharge guidance. Results: TTe graffs in 4 cases were displaced, and were all in place affer resetting. The bubble was observed in posterior chamber in 1 case, this case was taken anterior chamber forming operation. Intraocular pressure was high in 13 cases, and those cases were treated with topical medicines. Conclusion: Completing the preoperative nursing of patients with corneal endothelial transplantation, observing the complications and taking corresponding treatment and nursing measures help improve the success rate of the operation.

Objective: To investigate nursing and cooperation of femtosecond laser-assisted endothelial keratoplasty (EK). Methods: Preoperative visit and adequate preoperative preparation were proceeded in 19 patients (19 eyes) underwent femtosecond laser-assisted EK, instrument commissioning and equipment preparation were performed before the surgery. We mastered the surgical procedures, guided patients for cooperating the operation, and cooperated closely with surgeon during operation. Management of intraoperative and postoperative body position were accomplished, instruments and equipment were well processed aff er operation. Results: All of the 19 cases were successfully completed without intraoperative accident, all of the patients cooperated actively.
