To determine the risk for rhegmatogenous retinal detachment (RRD) after phacoemulsification.
Private and public facility, Auckland, New Zealand.
A retrospective study of 1793 consecutive patients having cataract surgery by phacoemulsification was performed. Patients younger than 40 years were excluded, as were patients who had cataract surgery after ocular trauma. Patients having cataract surgery combined with other ocular procedures such as keratoplasty, glaucoma drainage surgery, or posterior segment surgery were similarly excluded.
Rhegmatogenous retinal detachment occurred in 1.17% of the patients having cataract surgery. The risk was greater in patients younger than 50 years (5.17%) and less in those older than 70 years (0.64%). The median interval between cataract surgery and development of the retinal detachment was 39 months. The rate of retinal detachment was greater with complicated cataract surgery, but there was no increased risk for those eyes requiring neodymium:YAG laser capsulotomy.
The overall risk for RRD after cataract surgery by phacoemulsification was small. However, in the younger patient, the risk for pseudophakic detachment was higher. In light of this finding, the requirement for cataract surgery in this group should be reassessed.
确定白内障超声乳化术后发生孔源性视网膜脱离（RRD）的风险。
新西兰奥克兰的私立和公立机构。
对1793例连续接受白内障超声乳化手术的患者进行回顾性研究。排除40岁以下的患者以及眼部外伤后接受白内障手术的患者。同样排除接受白内障手术并联合其他眼科手术（如角膜移植术、青光眼引流手术或后段手术）的患者。
白内障手术患者中孔源性视网膜脱离的发生率为1.17%。50岁以下患者的风险更高（5.17%），70岁以上患者的风险更低（0.64%）。白内障手术与视网膜脱离发生之间的中位间隔时间为39个月。复杂白内障手术的视网膜脱离发生率更高，但对于需要钕:钇铝石榴石激光晶状体后囊切开术的眼睛，风险并未增加。
白内障超声乳化术后发生RRD的总体风险较小。然而，在年轻患者中，人工晶状体性视网膜脱离的风险更高。鉴于这一发现，该组患者白内障手术的必要性应重新评估。
