Contact lens Most people who do not have an IOL wear soft contact lenses. Extended-wear lenses are helpful if you have trouble putting in and taking out contacts. With all contact lenses, it's important for you to follow instructions about proper use and care. Cataract glasses Some people don't want to use contact lenses or their eyes are too sensitive to wear them. For these people, cataract glasses may be the best choice.
Cataract glasses affect vision differently than regular eyeglasses.
Until you've adjusted to these changes, you will need to be careful when you drive or do other activities. Before surgery, your eye care professional will do some tests. Other tests may help to determine the health of the retina and to guide the surgery. Photographs of your eye may also be taken before or after surgery. Many people choose to stay awake during surgery, while others may need to be put to sleep for a short time.
