Structural changes of the eye in old paitent?
There are many different things, depending on the eye of the patient. The main thing is that the crystalline lens becomes thicker and stiffer removing the ability to focus. The lens can also become cloudy which is called a cataract. There are also lots of other things that can occur.
What causes of cataract?
A cataract is a very common condition of the lens (a structure located inside the eye which, along with the cornea, focuses light on the retina for clear vision). A cataract is a clouding or opacity of the lens that results in decreased vision, glare, and/or haloes around lights. If these symptoms interfere with one's quality of life, an ophthalmologist can remove the lens and replace it with an artificial lens. Cataract surgery is one of the most common surgeries performed in developed countries. A number of factors increase the likelihood of cataract formation, with increasing age being the most common cause, in addition to trauma, frequent ocular steroid administratioon, prior intraocular surgery (e.g., for glaucoma and retinal detachment), various disorders of the body (e.g., diabetes), other disorders of the eye (e.g., intrraocular inflammation called "uveitis"), the use of non-ocular medications (e.g., amiodarone, which is used to treat abnormal heart rhythms), and many others. Congenital cataracts (meaning present at birth) require prompt removal because they can cause irreversible vision loss in infants; by preventing light from reaching the retina, the area of the brain responsible for interpreting signals from the eye do not have an opportunity to develop properly. It is important to note that almost everyone over rhe age of 40 has some degree of lens clouding and thus technically has a cataract. But only visually signicant cataracts (i.e., those causing symptoms) should be of any concern to the patient or physician.

Will you need far or near glasses after Cataract Surgery?
Now when they remove the cloudy lenses in Cataract Surgery they replace them with plastic lenses focused for far vision, so you will need glasses for near vision. Many people get bifocals with no prescription for the main lens part and the near vision prescription for the bifocal part. Other people just carry prescription near vision glasses for when they need to look at things close up but normally wear no glasses at all.Years ago (before they began putting in plastic lenses) everyone needed glasses all the time after having Cataract Surgery, because there was no longer any lens in the eye to focus the light.

What part of the eye causes blindness?
A cataract is the clouding of the lens. Crystallins are water-soluble structural proteins found in the lens of the eye; these are what are responsible for the transparency in the lens. These proteins are arranged in a precise way that keep the lens clear and let light pass through it. As we age, the proteins begin to clump together causing that part of the lens to cloud. Essentially it is the lens that is affected.
