Thirty-seven Q-switched neodymium-YAG laser posterior capsulotomies were performed on 33 aphakic or pseudophakic eyes. The average intraocular pressure increase during the first 24 hours after treatment was 12.0 +/- 6.9 mm Hg from a baseline value of 17.7 mm Hg in the treated eye v +0.7 +/- 3.5 mm Hg in the untreated eye. Seven eyes had larger capsulotomies performed, averaging 250.7 millijoules (mJ) of energy per treatment. Thirty eyes had smaller posterior capsulotomies performed, averaging 48.3 mJ per treatment. Average IOP increases within the first day were 16.1 and 12 mm Hg, respectively. All eyes in which IOP increased more than 5 mm Hg showed the increase within the first 48 hours. In some eyes, IOP remained elevated more than 10 mm Hg above preoperative levels for several weeks. Higher pressures were associated with larger capsulotomies and increased energy. Minimizing debris and shock waves are recommended as well as thorough postoperative pressure monitoring.
对33只无晶状体或人工晶状体眼进行了37次Q开关钕钇铝石榴石激光后囊切开术。治疗后第1天，治疗眼的眼压平均升高12.0±6.9mmHg，治疗前眼压基线值为17.7mmHg，而未治疗眼的眼压升高0.7±3.5mmHg。7只眼进行了较大的囊切开术，每次治疗平均能量为250.7毫焦（mJ）。30只眼进行了较小的后囊切开术，每次治疗平均能量为48.3mJ。第一天内眼压平均升高分别为16.1和12mmHg。所有眼压升高超过5mmHg的眼均在最初48小时内出现眼压升高。在一些眼中，眼压持续高于术前水平10mmHg以上数周。较高的眼压与较大的囊切开术和增加的能量有关。建议尽量减少碎片和冲击波，并进行全面的术后眼压监测。
