方法：随机选取2015-01/08在我院眼科接受LASEK的近视患者53例106眼，分别在术前、术后1、3、6mo，1a应用Sirius眼前节分析仪测量中央前房深度、前房角度、前房容积，并对测量结果进行统计学分析。

结果：LASEK术后1a内，中央前房深度和前房容积较术前显著减小(P<0.05)，前房角较术前无变化(P>0.05)； LASEK术后1a内各个时间点，中央前房深度、前房角度、前房容积均无变化(P>0.05)。

结论：LASEK术后中央前房深度、前房容积均较术前降低，而术后1a内中央前房深度、前房容积无变化，前房角度在LASEK手术前后无变化。因此，在随访期内LASEK术后前房形态无变化。

METHODS:A total of 53 cases(106 eyes)with myopia underwent LASEK were randomly selected from Jan.2015 to Aug.2015. Applications of Sirius anterior segment analyzer measure the eyes' central anterior chamber depth, anterior chamber angle and anterior chamber volume before operation and at 1, 3, 6mo, 1y after operation.

RESULTS: Within 1 year after LASEK, central anterior chamber depth and volume compared with the preoperative decreased significantly(P<0.05). The anterior chamber angle than preoperative no change(P>0.05). Each time point within 1 year after LASEK, central anterior chamber depth, anterior chamber angle, anterior chamber volume did not change(P>0.05).

CONCLSION: The central anterior chamber depth and anterior chamber volume is decreased after LASEK, but the depth of the anterior chamber and the volume of the anterior chamber are unchanged in 1 years after the operation. The anterior chamber angle is not changed after LASEK operation. Therefore, in the follow-up period, the morphology of the anterior chamber is stable after LASEK.
