These symptoms can also be signs of other eye problems. Just because you have a cataract does not mean that you need it removed right away. A change in your glasses, stronger bifocals, or the use of magnifying lenses and better lighting may help you see better and may be treatment enough. In fact, you may never need cataract surgery. Many people put off having surgery until their vision becomes difficult or unacceptable.
Cataract surgery involves two steps.
Sometimes the surgeon will use sound waves to soften the lens and remove it through a needle. In most cases, your lens is replaced with a clear plastic lens at the same time. This artificial disc, called an intraocular lens, is placed in the lens capsule inside your eye. If an intraocular lens is not inserted, you will require either contact lenses or cataract glasses. You probably won't need to stay overnight in a hospital to have cataract surgery.
