What happens if they remove the lens from eye?

If the lens is surgically removed from the eye, a condition called aphakia occurs. Aphakia results in severe hyperopia, or farsightedness, making it difficult to see objects up close. This condition can be corrected with eyeglasses or contact lenses that have a strong positive refractive power, or with intraocular lens implants (IOLs).

IOLs are artificial lenses that are implanted in the eye to replace the natural lens that has been removed. They are typically made of a flexible material and are inserted through a small incision in the cornea. IOLs help to restore clear vision and reduce the need for corrective eyewear.

The process of removing the lens from the eye is known as lens extraction or cataract surgery. It is a common surgical procedure that is performed to treat cataracts, which are a clouding of the natural lens that can lead to blurred vision, glare, and other symptoms.
