摘要： 目的观察准分子激光原位角膜磨镶术(LASIK)对视网膜功能和视神经纤维层厚度的影响。方法近视眼患者15例30眼,术前经严格检查后行LASIK。术前、术后1d、7d、1个月、3个月、6个月检查裸眼和矫正视力,散瞳验光测量屈光度,非接触眼压计测量眼压,AB超测量角膜厚度及眼轴长度,角膜地形图扫描,间接眼底镜散瞳下检查眼底,并行视网膜电流图、视觉诱发电位测定及光学相干断层扫描。结果LASIK术后早期眼压无明显变化,视觉电生理无明显变化;术后1周,平均视神经纤维层厚度降低(P<0.05),术后1～6个月神经纤维层厚度逐渐恢复至术前水平。结论LASIK对近视眼患者术后的视网膜功能和视神经纤维层厚度无明显影响。

Abstract: ObjectiveTo observe the retinal function and nerve fiber layer (RNFL) thickness after laser in situ keratomileusis (LASIK). MethodsLASIK was performed in 15 cases (30 eyes) with myopia after strict preoperative examination. All examinations such as vision, correction vision, diopter, intraocular pressure, corneal thickness, ocular axis, topography scan and fundus of eye examination were performed before and 1 day, 1 week, 1 month,3 months and 6 months after operation, as well as electroretinography (ERG), visual evoked potential (VEP), optical coherece tomography at same time. ResultsThere was not significant difference in the intraocular pressure, ERG and VEP 1 day after LASIK. The thickness of RNFL decreased 1 week after LASIK (P<0.05) and recovered 1～6 months later. ConclusionLASIK does not disturb the retinal function and RNFL thickness irreversiblely.
