目的探讨白内障囊外摘出人工晶状体植入术后眼压的变化。方法63例随机分为甲组（不用药组）、乙组（用降眼压药组），观察和对比术后72小时内眼压。结果术后12小时＞2．80kPa者，甲组占54．5％，乙组占26．67％。24小时后眼压下降。72小时平均眼压甲组明显高于乙组（P＜0．05）。结论术后预防性应用降眼压药对降低人工晶状体植入术后眼压升高有明显作用。
Objective To investigate the changes of intraocular pressure after extracapsular cataract extraction with intraocular lens implantation. Methods 63 cases were randomly divided into group A (no drug group) and group B (intraocular hypotensive group). Intraocular pressure (IOP) was observed and compared within 72 hours after operation. Results After 12 hours> 2.80kPa, group A accounted for 54.5%, group B accounted for 26.67%. IOP drops after 24 hours. The average intraocular pressure in 72 hours group was significantly higher than that in group B (P <0.05). Conclusions The prophylactic use of antihypertensive drugs after IOP has a significant effect on lowering intraocular pressure after intraocular lens implantation.
