The effects of using epinephrine in the irrigating fluid and intracameral acetylcholine were studied by measuring changes in pupil size in the 48 hours following extracapsular cataract extraction and intraocular lens implantation in 39 eyes. Epinephrine reduced peroperative pupil constriction, but its effect was insignificant thereafter. The pupil constriction following acetylcholine was maximal at 2 hours and was still significant at 4 hours, but pupils redilated by 6 hours. Neither drug had any effect after this time. The edge of most lens implants was visible at 6 hours, after which pupils steadily constricted.
通过测量39只眼睛在白内障囊外摘除及人工晶状体植入术后48小时内瞳孔大小的变化,研究了在冲洗液中使用肾上腺素及前房内使用乙酰胆碱的效果。肾上腺素减少了术中瞳孔收缩,但此后其效果不显著。乙酰胆碱引起的瞳孔收缩在2小时时最大,4小时时仍显著,但6小时时瞳孔重新散大。在此之后两种药物均无任何作用。大多数人工晶状体的边缘在6小时时可见,此后瞳孔逐渐收缩。
