BACKGROUND AND OBJECTIVE
To measure the foveal thickness change after Nd:YAG laser capsulotomy by optical coherence tomography (OCT).
PATIENTS AND METHODS
Fifty-four eyes of 54 patients who had posterior capsule opacification underwent Nd:YAG laser capsulotomy. OCT of the foveal region was performed preoperatively and postoperatively (on days 1 and 7 and months 1, 3, 6, and 12). The preoperative and postoperative measurements were compared.
RESULTS
The foveal thickness did not significantly change in the first year after laser treatment. Cystoid macular edema developed in only 1 patient (2%). Patient age and gender, time between surgery and laser capsulotomy, total laser shots, total laser energy, or mean laser energy per shot did not affect the foveal thickness.
CONCLUSION
Foveal thickness does not change in the first year after Nd:YAG laser capsulotomy, as determined by OCT.
背景与目的
通过光学相干断层扫描（OCT）测量钕钇铝石榴石激光晶状体后囊切开术后黄斑中心凹厚度的变化。
患者与方法
54例患有后囊膜混浊的患者的54只眼睛接受了钕钇铝石榴石激光晶状体后囊切开术。在术前以及术后（第1天、第7天、1个月、3个月、6个月和12个月）对黄斑区进行OCT检查。比较术前和术后的测量结果。
结果
激光治疗后的第一年，黄斑中心凹厚度没有显著变化。仅1例患者（2%）发生了黄斑囊样水肿。患者的年龄和性别、手术与激光晶状体后囊切开术之间的时间间隔、激光总击射次数、激光总能量或每次击射的平均激光能量均未影响黄斑中心凹厚度。
结论
根据OCT测定，钕钇铝石榴石激光晶状体后囊切开术后的第一年，黄斑中心凹厚度没有变化。
