常规白内障囊内摘除术,完成180°角膜缘切口后,常引起瞳孔缩小,继而影响晶状体的娩出。实验证明此现象与手术刺激使前列腺素大量合成与释放有关。消炎痛可以抑制前列腺素的合成,起到对抗瞳孔缩小的作用,已为临床所采用。本文旨在观察口服消炎痛在白内障摘除术中对缩瞳的抑制作用。 Conventional cataract extraction, the completion of 180 ° limbal incision, often cause miosis, which in turn affects the delivery of the lens. Experiments show that this phenomenon and surgical stimulation of prostaglandin synthesis and release of a large number of related. Indomethacin can inhibit prostaglandin synthesis, play a role in confrontation pupil reduction, has been used clinically. This article aims to observe the inhibitory effect of oral indomethacin on miosis in cataract extraction.
