必须强调,白内障囊内或囊外摘出术时,晶体囊的处理正确与否,是关系到手术的过程和术后效果的决定性因素。就人工晶体植入术而言,晶体囊为虹膜-囊型和后房型人工晶体的主要支持物,并与睫状小带一起稳定和分隔着眼球内容物。本文就晶体囊的组织、生理、病理以及在白内障手术中的处理进行综述。一、晶体囊的解剖晶体囊与角膜后弹力膜和Bruch膜同属来自外胚层的透明膜。胚长12mm时,晶体泡自体表外胚层分离形成晶体囊原基,在此前若用扫描电镜检查即可辨认。有人认为,晶体囊于出生后
It must be emphasized that the cataract cyst or extracapsular cataract extraction, the treatment of crystal capsule is correct or not, is related to the operation process and postoperative outcome of the decisive factor. For intraocular lens implantation, the crystalline capsule is the primary support for iris-capsule and posterior chamber intraocular lenses and, together with the ciliary strip, stabilizes and separates the contents of the eyeball. This review summarizes the organization, physiology and pathology of lens capsule and the treatment of cataract surgery. First, the anatomy of the crystalline capsule Crystal capsule and the corneal membrane and Bruch film belong to the ectoderm from the transparent membrane. When the embryo length is 12mm, the crystal vesicles are separated from the epidermal ectoderm of the epidermis to form the crystalline capsule primordium, which can be identified by scanning electron microscopy before. Some people think that the crystal capsule after birth
