白内障超声乳化囊膜破裂人工晶状体植入术后并发症

探讨了白内障超声乳化囊膜破裂行后房型人工晶状体植入术后并发症及视力结果．病例为解放军总医院眼科1999年1月至2002年12月因老年性白内障实施超声乳化及后房型人工晶状体植入术的患者．其中囊膜破裂64眼；囊膜完整164眼．结果表明视力在0．8或以上病例囊膜完整组明显多于囊膜破裂组．视网膜脱离、黄斑囊样水肿、眼压升高、人工晶状体偏位等并发症囊膜破裂组明显高于囊膜完整组．囊膜完整组视力明显好于囊膜破裂组．囊膜破裂组视网膜脱离、黄斑囊样水肿、眼压升高及人工晶状体脱位等并发症比较常见．因此，这些病例应该给予较长时间观察．

Complications of posterior chamber intraocular lens implantation after capsular tear during phacoemulsification

OBJECTIVE: To determine the visual outcome and complications of posterior chamber intraocular lens implantation after capsular tear in patients undergoing phacoemulsification. METHODS: The patients who underwent phacoemulsification surgery for senile cataract from January, 1999, to December, 2002, were reviewed. Patient inclusion criteria were implantation of a posterior chamber intraocular lens after phacoemulsification, being operated on by one of the surgeons, and a follow-up of at least 1 year. There were 64 eyes in the group with capsular tear and 164 eyes in the group with intact capsule. RESULTS: A final visual acuity of 0.8 or more in the group with intact capsule was more common. Complications such as retinal detachment, cystoid macular edema, increased intraocular pressure and decentration of the intraocular lens were more frequently observed in eyes with capsular tear. CONCLUSIONS: A final visual acuity in the group with intact capsule was more better than that in the group with capsule tear. Complications such as retinal detachment, cystoid macular edema, increased intraocular pressure and decentration of the intraocular lens are more common in these patients with capsular tear, and therefore they should be observed for a longer period of time.
