INTRODUCTION
Thermal conditions during photorefractive keratectomy might be an important issue related to the corneal wound healing and long-term outcomes.
AIM
Authors tried to find out the importance of temperature conditions during the treatment.
METHOD
One eye of 90 patients has been included into the study. Photorefractive keratoctomy was applied with Carl Zeiss MEL 70, MEL 80 and Wavelight Allegretto excimer lasers. EBRO TLC 730 infrared thermometer was used for the measurement of surface temperature of the cornea before epithelial removal, as well as before and after the treatment. Average age of the patients was 25.5 ± 3 yr. Average myopic correction was -3.2 ± 0.8 Dpt.
RESULTS
Statistically significant difference was found in temperature change between MEL 80 and the other two types of excimer laser devices.
CONCLUSIONS
Different air flow conditions of the smoke removal system might have an influence on changes of the corneal temperature during treatment, but the refractive results were not influenced by this issue. Orv. Hetil., 2016, 157(43), 1717-1721.
引言
准分子激光原位角膜磨镶术（PRK）过程中的热条件可能是与角膜伤口愈合及长期预后相关的重要问题。
目的
作者试图探究治疗过程中温度条件的重要性。
方法
90例患者的一只眼睛纳入研究。使用卡尔·蔡司MEL 70、MEL 80和威视 Allegretto准分子激光进行准分子激光原位角膜磨镶术。采用EBRO TLC 730红外温度计测量上皮去除前以及治疗前后角膜表面温度。患者平均年龄为25.5±3岁。平均近视矫正度数为-3.2±0.8屈光度。
结果
发现MEL 80与其他两种准分子激光设备之间的温度变化存在统计学显著差异。
结论
排烟系统不同的气流条件可能会影响治疗过程中角膜温度的变化，但屈光结果不受此问题影响。《匈牙利医学周报》，2016年，157(43)，1717 - 1721。
