用于白内障超声乳化训练的活体白内障动物模型

目的：制备用于白内障超声乳化训练的活体白内障动物模型。方法：狗在全身麻醉下用26号带有斜面的针刺破左眼的晶状体前囊，制备白内障模型，形成白内障后，行超声乳化手术。结果：眼部检查显示晶状体后部皮质混浊开始于穿刺术后5～7d，并于术后75d白内障全部形成，在所有的白内障形成的眼上行超声乳化手术，并植入人工晶状体，所有的狗均恢复了视力。结论：考虑到无经验的眼科医生在行白内障超声乳化手术的初始阶段引起的巨大损失，我们认为这个活的动物模型明显优于目前用于训练超声乳化手术的尸体眼。

Live animal model of cataract for surgical training n phacoemulsification

AIM： To create a live animal model of cataract for training in phacoemulsification.
METHODS： The left eye of each dog was selected, and cataract was induced by puncturing the anterior capsule of the lens with the beveled end of the 26 gauge needle under general anesthesia. Phacoemulsification was performed in all the eyes following development of cataract.
RESULTS： Ophthalmologic examination showed posterior cortical opacification started from day 5 to 7 after the induction and the complete cataract formation was observed at 75 days post the induction. The phaco-chop technique was practiced in all the dogs, followed by placement of intraocular lens. Vision was restored in all the dogs following the phacoemulsification.
CONCLUSION： Considering the enormous losses caused initially by inexperienced surgeons while performing phacoemulsification, we suppose that this live animal model will be far superior to cadaver eyes that are commonly used for practice of phacosurgery.
