儿童白内障手术后眼球的屈光状态是变化的,且有普遍向近视发展的趋势,这现象称为近视漂移(my- opic shift)。儿童白内障手术后无晶体眼的矫正方法有框架眼睛、角膜接触镜、角膜屈光手术和人工晶状体植入等。框架眼镜和角膜接触镜的屈光度易调整,但眼镜成像质量差,而接触镜需常更换、易脱落丢失、还可能诱发角膜感染,患儿对这两种方法的依从性较差。人工晶状体植入可避免上述问题,可人工晶状体屈光度固定,植入后不能随意调换。因此,对儿童白内障手术后近视漂移的研究以及如何正确选择儿童人工晶状体度数显得尤其重要。现对近视漂移的研究进展进行综述。
The refractive status of the eyeball after cataract surgery in children is changing, and there is a general tendency to develop myopia. This phenomenon is called myopic opacity shift. Aphakia after cataract surgery in children with the correction of the framework of the eye, contact lenses, corneal refractive surgery and intraocular lens implantation. Frame glasses and contact lenses are easy to adjust the diopter, but the poor quality of the glasses, and contact lenses need to be replaced often easy to fall off, may also induce corneal infection, children with poor compliance of these two methods. Intraocular lens implantation to avoid the above problems, intraocular lens can be fixed refractive, can not be freely replaced after implantation. Therefore, the study of children with cataract surgery after myopia drift and how to correctly select the degree of child intraocular lens is particularly important. Now the research progress of myopia drift are reviewed.
