探讨和分析准分子激光屈光性角膜术后（ＰｈｏｔｏｒｅｆｒａｃｔｉｖｅＫｅｒａｔｅｃｔｏｍｙ，ＰＲＫ）和准分子激光原位角膜磨镶术（Ｌａｓｅｒｉｎ－ｓｉｔｕＫｅｒａｔｏｍｉｌｅｕｓｉｓ，ＬＡＳＩＫ）治疗近视后非接触式眼压的变化。方法：对ＰＲＫ术后７０例１３０眼和ＬＡＳＩＫ术后３１例６０眼采用非接触式眼压计（ＮｏｎｃｏｎｔａｃｔＴｏｎｏｍｅｔｅｒ，ＮＣＴ）测量眼压，随访半年以上，将术前和术后眼压平均值进行比较。结果：术前两组眼压平均值差异不显著（ｕ检验，Ｐ＞０．０５），术后两组较术前下降均明显（Ｐ＜０．０１），且ＬＡＳＩＫ组术后眼压下降比ＰＲＫ组更显著（Ｐ＜０．０１），而切削量相当的两组术后眼压下降均值差异不显著（ｔ检验，Ｐ＞０．０５）。结论：ＰＲＫ和ＬＡＳＩＫ术后６月以上非接触式眼压均值较术前明显下降，随着切削量的增加，眼压值下降趋于明显，术后非接触式眼压值并不能完全反映其实际眼内压，对其判断需考虑多方面的因素，出现以下情况应进一步检查以免影响对激素性高眼压和／或激素性青光眼的判断和处理：（１）术后非接触式眼压高于术前。（２）术后非接触式眼压结合切削量酌情加０～１．４５ｋＰａ达激素性高眼压标准。（３）术后随访过程?
To investigate the changes of non-contact intraocular pressure (IOP) after laser photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) for the treatment of myopia. Methods: The intraocular pressure (IOP) was measured in 130 eyes after PRK and in 31 eyes (60 eyes) after LASIK. The intraocular pressure was measured by noncontact tonometer (NCT). The mean IOP before and after surgery were compared . Results: There was no significant difference between the two groups in preoperative IOP (u test, P> 0.05). The postoperative IOP decreased significantly in both groups (P <0.01), and the IOP decreased in LASIK group (P <0.01). However, there was no significant difference between the two groups in the amount of postoperative IOP reduction (t test, P> 0.05). CONCLUSIONS: The average non-contact intraocular pressure (IOP) of patients undergoing PRK and LASIK for more than 6 months decreased significantly compared with that before operation. With the increase of the amount of cutting, the intraocular pressure (IOP) decreased significantly, and postoperative non-contact IOP did not fully reflect The actual intraocular pressure, to judge its need to consider many factors, the following conditions should be further checked so as not to affect the determination and treatment of steroid-induced hypertension and / or hormonal glaucoma: (1) postoperative non-contact intraocular pressure Higher than preoperative. (2) postoperative non-contact intraocular pressure combined with cutting appropriate amount of 0 ~ 1.45kPa up to the standard high intraocular pressure. (3) postoperative follow-up process?
