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：探讨大泡性角膜病变(bullous keratopathy，BK)患者行飞秒激光辅助的角膜内皮移植术(endothelium keratoplasty，EK)的围手术期护理。方法：回顾性分析在南京总医院眼科行飞秒激光辅助角膜内皮移植的BK20例患者，分析并总结患者术前的心理疏导、术前准备、眼科检查、术中如何配合医生、术后特殊体位、高眼压的护理及如何正确用药和出院健康教育等。结果：患者得到及时、有效的护理，术后视力均有所提高，内皮贴伏好，无排斥反应及其他并发症的发生。结论：通过对患者围手术期的护理，可提高护理质量，缩短患者住院时间。

Objective: To observe the perioperative nursing of femtosecond laser-assisted corneal endothelial transplantation in the treatment of patients with bullous keratopathy. Methods: A retrospective analysis of 20 patients with bullous keratopathy with femtosecond laser-assisted corneal endothelial transplantation in our department. The preoperative psychological counseling, preoperative preparation, ocular examination, how to cooperate with the doctors in operation, nursing of special position, high intraocular pressure after surgery, how to use eye drops correctly and health education after discharge were summarized. Results: Nursing were performed to the patients timely and effectively. Postoperative visual acuity of all the patients were improved, the endothelial and corneal stroma bed are well combined and no graft rejection and other complications occurred in the patients postoperatively. Conclusion: We concluded that the quality of nursing was improved and the time of hospitalization was shortened after perioperative nursing.

目的：了解行全飞秒激光小切口角膜基质透镜取出术(small incision lenticule extraction，SMILE)患者围手术期的体验感受。方法：采用定性调查的方法，选取广东省某医院的15名行SMILE的患者，进行半结构式访谈，将患者围手术期体验归纳为顾虑、紧张、疼痛、担心、放松5个主题概念，用现象学分析法整理、分析资料。结果：把5种体验汇总制成韦恩图，通过韦恩图提炼发现有1人有围手术期5种感受，3位有紧张、疼痛、担心、放松4种心理感受，2位只有紧张的感受，而无其余感受。结论：行SMILE患者的围手术期具有多种体验感受，分析不同感受状态和因素，为眼科医护人员对于寻求SMILE手术的患者做好围手术期的服务提供依据。

Objective: To investigate the perioperative experience after small incision lenticule extraction (SMILE). Methods: A semi-structured interview was conducted in 15 patients who underwent SMILE surgery in Zhuhai People’s Hospital.The data were collected and analyzed by phenomenological analysis. Results: The perioperative feelings of patients were summarized into five categories: concern, tension, pain, worry and relaxation. These feelings were compiled and extracted by Venn diagram. One patient had all five categories of feelings during the perioperative period. Three patients experienced four psychological feelings of tension, pain, worry and relaxation, and 2 patients had only nervous feelings during the full femtosecond operation period. Conclusion: Patients undergoing SMILE have avariety of experience feelings during perioperative period. Analysis of different feeling states and factors will provide evidence for ophthalmic medical staff to provide perioperative services for patients seeking SMILE surgery.
