What type of cataract is associated with myopia?

How does myopia cause cataract?

While the exact cause remains a gray area, researchers suggest that the increasing axial eyeball length in myopic eyes may prevent nutrient delivery to the back side of the lenses. As a result, they lose their clarity and begin forming cataracts.

Can high myopia cause cataract?

Unfortunately, patients with high myopia can develop cataracts earlier than those with no refractive errors, perhaps with visible cataracts appearing before 60. They’re about 3 times more likely to develop cataracts than those without, and recovery from cataract surgery is worse.
