Why don't myopia cut lenses?

There are no blood vessels in the lens, and the nutrition it needs comes from aqueous humor. If the metabolism of aqueous humor is disordered, or the lens capsule is damaged, the lens will be turbid due to lack of nutrition, and the originally transparent lens will become milky white and opaque, which will eventually affect vision. This is a cataract.

I estimate that if the lens is cut, it will be damaged. It may be a water sac instead of a lens, and corneal ablation can automatically repair it.
