超声乳化联合人工晶状体植入术对眼压的影响

The influence of phacoemulsification and intraocular lens implantation on intraocular pressure

目的观察白内障超声乳化摘除联合折叠式人工晶状体植入术后眼压的变化。方法选取具有正常前房深度、宽房角结构和浅前房、窄房角结构的白内障患者各30例(30只眼),均接受白内障超声乳化摘除联合人工晶状体植入术。对2组患者术前及术后2周、1、3个月行眼压检查,并进行统计学分析。结果手术后2周、1、3个月,2组患者眼压均较术前下降,差异有统计学意义(P<0.05),其中,浅前房深度组患者眼压下降更为明显;2组患者术后2周、1、3个月眼压相比较,差异无统计学意义(P>0.05)。结论白内障超声乳化摘除联合折叠式人工晶状体植入术能明显降低患者的眼压,可预防青光眼的发生,并可作为治疗闭角型青光眼合并白内障的一种手术方法。

Objective Observe the influence on intraocular pressure （IOP） of phacoemulsification and intraocular lens implan- tation. Methods Phacoemulsification and intraocular lens implantation were performed in 60 eyes of 60 patients whom were divided into two groups：one group with shallow anterior chamber and narrow anterior chamber angle structure, another group with normal anterior chamber structure. The IOP of all the patients was measured at the time before surgery and two week, one month and three months after surgery. Results The IOP of both groups was lower after operation than pre - operation （ P 〈 0.05 ）. The IOP of shallow anterior cham- ber depth group decreased more significantly （P 〈 0.05 ）. Comparing the IOP at each time after operation with another, there was no sig- nificant difference （ P 〉 O. 05 ）. Conclusion Phacoemnlsification and foldable intraocular lens implantation can significantly reduce the IOP of patients and avoid the occurrence of glaucoma. So that it is a surgery method of treating angle - closure glaucoma combined cata- ract patients.
