手术室温度对FS-LASIK术后结果的影响

The Effect of Operating Room Temperature on FS-LASIK Outcomes

摘要: 目的：探讨手术室温度对飞秒激光制瓣的准分子激光原位角膜磨镶术(Femtosecond laser-assisted in situ keratomileusis, FS-LASIK)术后结果的影响。方法：回顾性研究。收集我院2023-05/2023-10行FS-LASIK的病例，抽取年龄、屈光度数、角膜厚度、角膜曲率、手术室湿度差异小，但手术时温度不同的病例分为三组，每组20人40只眼，共60人120只眼。A组手术室温度为20.0℃~20.5℃，B组为22.0℃~22.5℃，C组为24.0℃~24.5℃。手术由同一位手术医生、同样的设备完成，术后统一用药。比较三组术后3个月时裸眼视力与屈光度的差异情况。结果：不同手术温度组在术后3月比较时，未发现裸眼视力及屈光度之间存在统计学差异(P > 0.05)。三组患者术后3个月裸眼视力、等效球镜度数不满足正态分布，采用Kruskal-Wallis法进行检验。术后裸眼视力比较无统计学意义(H = 2.648, P = 0.266)。三组患者术后等效球镜度数比较无统计学意义(H = 1.010, P = 0.604)。结论：空气中的温度及湿度的明显变化才能对准分子激光能量产生显著影响。湿度可能较温度的影响更大。本文研究结果未发现在设备商推荐温度范围内变化时，对FS-LASIK术后视力屈光度产生有统计学意义的显著影响。

Abstract: Aim: To explore the effect of operating room temperature on the postoperative outcomes of femtosecond laser-assisted in situ keratomileusis (FS-LASIK). Methods: Retrospective study. Collecting cases that underwent FS-LASIK in our hospital from May 2023 to October 2023, cases were extracted with small differences in age, diopters, corneal thickness, corneal curvature, and operating room humidity. Cases with different temperatures during surgery were divided into three groups. Each group has 20 people with 40 eyes, a total of 60 people with 120 eyes. The operating room temperature in group A was 20.0˚C~20.5˚C, in group B was 22.0˚C~22.5˚C, and that in group C was 24.0˚C~24.5˚C. The surgery was completed by the same surgeon and the same equipment, and the same postoperative medication was used. The differences in naked eye visual acuity and diopters between the three groups were compared 3 months after surgery. Results: Comparing different surgical temperature groups 3 months after surgery, no statistical difference was found between naked eye visual acuity and diopters (P > 0.05). The naked visual acuity and spherical equivalent refraction of the three groups 3 months after surgery did not satisfy the normal distribution, and the Kruskal-Wallis method was used to test. There was no statistical significance in postoperative naked eye visual acuity (H = 2.648, P = 0.266). There was no statistical significance in the postoperative spherical equivalent refraction of the three groups (H = 1.010, P = 0.604). Conclusion: Only significant changes in temperature and humidity in the air can have a significant impact on excimer laser energy. Humidity may have a greater impact than temperature. The results of this study did not find that changes in the temperature range recommended by the equipment manufacturer have a statistically significant impact on the visual acuity and diopters after FS-LASIK.
