We retrospectively studied the long-term change in intraocular pressure after neodymium-YAG laser posterior capsulotomy. Uncomplicated extracapsular cataract extraction with posterior chamber intraocular lens implantation was performed in 446 consecutive normal eyes (401 patients), 237 (53%) of which subsequently underwent uncomplicated neodymium-YAG laser posterior capsulotomy. Late-onset elevation in intraocular pressure was seen in three eyes (1.4%) after cataract surgery alone (mean follow-up, 2.7 +/- 1.7 years) and in 14 eyes (5.9%) after cataract and laser surgeries (mean follow-up, 3.0 +/- 1.1 years). This difference was statistically significant (P less than .03). These results suggest that, in addition to immediate changes in intraocular pressure, neodymium-YAG laser posterior capsulotomy may be associated with an increase in intraocular pressure long after the laser surgery, even in normal eyes without obvious postoperative complications.
我们回顾性研究了钕-YAG激光后囊切开术后眼压的长期变化。对446只连续的正常眼（401例患者）进行了无并发症的囊外白内障摘除联合后房型人工晶状体植入术，其中237只眼（53%）随后接受了无并发症的钕-YAG激光后囊切开术。单纯白内障手术后3只眼（1.4%）出现迟发性眼压升高（平均随访2.7±1.7年），白内障和激光手术后14只眼（5.9%）出现迟发性眼压升高（平均随访3.0±1.1年）。这种差异具有统计学意义（P<0.03）。这些结果表明，除了眼压的即时变化外，钕-YAG激光后囊切开术可能与激光手术后很长时间眼压升高有关，即使是没有明显术后并发症的正常眼。
