摘要
散光根据来源分为角膜散光和眼内散光,角膜屈光力占全眼屈光力的70％,角膜是人眼散光的主要来源.角膜散光的来源分为先天性散光及后天性散光,某些微量元素缺乏可引起先天性散光,后天性散光的来源包括眼表因素、眼眶因素、手术因素及其他相关因素,后天性散光可通过手术或改变原有手术方式而降低.了解角膜散光的来源为未来探索新的减少术源性散光手术方式提供参考,并且为早期未影响视力时规避后天性散光的方法提供临床思路.(国际眼科纵览,2024,48:224-228)
Abstract
Astigmatism can be divided into corneal astigmatism and intraocular astigmatism based on their sources.Corneal astigmatism accounts for 70％of the total refractive power of the eye,and the cornea is the main source of human astigmatism.The sources of corneal astigmatism can be divided into congenital astigmatism and acquired astigmatism.Congenital astigmatism can be caused by certain trace element defi-ciencies,while acquired astigmatism can be caused by ocular surface factors,orbital factors,surgical fac-tors,and other related factors.Acquired astigmatism can be reduced through surgery or changing the original surgical method.Understanding of the sources of corneal astigmatism aims to provide clinical evidence for the development of new surgical methods to reduce surgical astigmatism in the future,and to provide clinical ide-as for avoiding acquired astigmatism in the early stages without affecting vision.(Int Rev Ophthalmol,2024,48:224-228)
