人工晶体植入术中,晶体的位置,支架的形状和固定方法要占主要地位。迄今为止能满足这种要求的首推SimcoeC型半环支架晶体,而一度受人鉴赏的ShearingJ型支架晶体,J的顶端角度虽几经改变仍不能与之比拟。C型半环支架晶体的优点在于最适合人眼 Intraocular lens implantation, the location of the crystal, the shape of the stent and the fixation method to dominate. So far to meet the requirements of the devaluation of SimcoeC half-ring stent crystal, once appreciated ShearingJ stent crystal, J’s top angle after several changes still can not be compared with. The advantage of a C-half-ring stent crystal is that it is best for the human eye
