Is old people eyesight drops to be caused by cataract

Not all cases of vision loss in the elderly are caused by cataracts, although cataracts are one of the most common causes. Other possible causes of vision loss in the elderly include age-related macular degeneration, retinal degeneration caused by myopia, diabetic retinal damage, etc. In addition, arteriosclerosis, narrowing of blood vessels, blockage of optic nerve vessels, and abnormal increase in intraocular pressure may also cause vision loss.

Therefore, when vision loss occurs in the elderly, it should be promptly seen to determine the cause. If cataract is caused, the elderly can be treated by intraocular lens implantation, laser surgery, etc.
