病变根本在晶状体呀。其他都是陪跑。相当于眼睛近视,戴眼镜鼻子耳朵遭罪。OK镜是角膜遭罪。从角膜正中点 ...
谢谢分享,我很好奇搜索了一下
看下来近视有几种情况,我们认为的是第一种,你说的第三种
The classification of myopia is essential for its appropriate management.
Axial myopia is the most common type observed in clinical practice and is caused by an increase in the axial length of the globe. A 1-mm increase in the axial length correlates with a myopic shift of 3 D, also known as spherical myopia.
Meridional myopia, also termed myopic astigmatism, is a condition in which myopia exhibits two foci along two axes. Regular myopic astigmatism is diagnosed when the meridional difference is along the vertical and horizontal axes. Oblique astigmatism occurs when the axis is not at 90 degrees or 180 degrees. The corneal curvature, not the axial length of the globe, mostly contributes to meridional myopia.
Lenticular myopia is the third most critical component of the myopic classification.
The crystalline lens undergoes substantial modifications with age, eventually contributing to changes in refractive error. Thus, the lenticular component should be examined for any myopic progression in adults. The severity of myopia is categorized as mild (between −0.5 and −4 D), moderate (between −4 and −8 D), and severe (> −8 D).
