方法：收集2014-01/06在我院就诊符合常规手术适应证并接受飞秒LASIK手术的患者共90例90眼，其中男47例47眼，女43例43眼，年龄18～33(平均22.38±3.96)岁。根据屈光度分为三组：A组：轻度近视组，30例30眼，≤3D； B组：中度近视组，30例30眼，>3～6D； C组：高度近视组，30例30眼，>6D。分别于术前、术后1，3mo行Pentacam检查测量前房相关参数，包括前房深度(ACD)、前房容积(ACV)、前房角(ACA)变化值。

结果：所有手术顺利，无并发症。A，B，C组术前与术后1，3mo时ACD和ACV比较，差异均有统计学意义(P<0.05)，而A组术后1，3mo时ACD和ACV值比较差异有统计学意义(P<0.05)，B组和C组术后1，3mo时ACD和ACV值比较差异无统计学意义(P>0.05)； 无论A组和B组还是C组，ACA值差异均无统计学意义(P>0.05)。屈光度与ACD，ACV，ACA变化值无明显相关性。

结论：飞秒LASIK术后早期引起前房参数变化，包括ACD变浅，ACV变小，但对周边前房角无明显影响，对屈光手术后行内眼手术患者有进一步指导作用。

METHODS:A total of 90 patients(90 eyes)in routine operation indications received FS-LASIK operation from January to June 2014 in our hospital were collected, including 47 males(47 eyes), 43 females(43 eyes), aged 18-33 years old(mean age 22.38±3.96 years). According to the diopter, the patients were divided into three groups: 30 cases(30 eyes)were in mild myopia group(group A)with diopter ≤3D; 30 cases(30 eyes)were in moderate myopia group(group B)with diopter >3D and ≤6D; 30 cases(30 eyes)were in high myopia group(group C)with diopter >6D. Pentacam measurements were used to measure the anterior chamber parameters including the changes of anterior chamber depth(ACD), anterior chamber volume(ACV), anterior chamber angle(ACA)before surgery and at 1, 3mo after surgery respectively.

RESULTS:All surgical procedures were performed successfully without complications. Compared with the value of ACD and ACV at pre-operation and 1, 3mo post-operation among groups A, B, C, there was statistically significant difference(P<0.05). In group A, there was statistically significant difference between the values of ACD, ACV at 1, 3mo post-operation(P<0.05), while in groups B, C, there was no statistically significant difference(P>0.05). However, in groups A, B and C, the value of ACA had no statistically significant difference(P>0.05). Diopter had no obvious relevance with the changes of ACD, ACV, ACA values.

CONCLUSION:The early changes of anterior chamber parameters after FS-LASIK, including that ACD become shallow, ACV become smaller, but there was no obvious effect on the peripheral anterior chamber angle. There will be a further instruction for those people who want to perform intraocular surgery after ocular refractive surgery.
