白内障是目前最主要的可治疗儿童致盲眼病。据估计,全世界有20万例因白内障而致盲的儿童(好眼的最佳矫正视力<0.05),每年又有约2～4万例患双眼发育性白内障的儿童出生,加之外伤性白内障,使得儿童病人占很大比例。特别是在发展中国家,需要提高对这些病例的早期诊断及相关处理水平。本文仅就儿童白内障人工晶体植入研究中的几个有争议的问题综述如下。1 儿童人工晶体植入和眼轴长度变化的关系 由于儿童眼球生长发育迅速,特别是2岁以前的婴幼儿,在其眼中植入人工晶体后将对其眼轴产生何种影响尚不十分清楚。Larmbert等选用新生猴子单眼植入普通长度的人工晶体后发现,所有人工晶体限眼轴长度均小于另一只
Cataracts are by far the most important eye diseases that can be treated in children. It is estimated that there are 200,000 children in the world who have been blind due to cataract (good eyes best corrected visual acuity <0.05) and about 240,000 children with cataract who are born with binocular development each year, combined with traumatic cataract , Making a large proportion of children’s patients. In developing countries in particular, there is a need to increase the level of early diagnosis and treatment of these cases. This article only summarizes several controversial issues in the study of cataract implantation in children. 1 children with intraocular lens implantation and changes in the length of the axial length of the child due to the rapid growth of eyeballs, especially infants and children before the age of 2 years, in their eyes implanted intraocular lens will have what effect on their ocular axis is not yet clear . Larmbert and other use of newborn monkeys monocular implantation of ordinary length of the intraocular lens and found that all the artificial lens axis length less than the other one
