A cataract is a clouding of the eye’s naturally clear lens. The lens focuses light rays on the retina – the layer of light-sensing cells lining the back of the eye – to produce a sharp image of what we see. When the lens becomes cloudy, light rays cannot pass through it easily, and vision is blurred.
There are no medications, eye drops, exercises or glasses that will help cataracts to disappear once they have formed. Surgery is the only way to remove a cataract. When you are not about to see well enough to do the things you like to do, cataract surgery should be considered.
Usually, with cataract surgery, a small incision is made in the eye. The front portion of the thin outer covering of the lens is opened to allow removal of the cataract inside.
The cataract is gently broken up and vacuumed out. Then a folded lens implant is inserted through the small incision and into the capsule where it unfolds and permanently takes the place of the clouded natural lens.
With the cataract removed, the new lens implant clearly focuses light rays onto the retina. The power of the lens implant is selected for your individual eye. However, you will probably need glasses to get your best near and far vision.
