What do you expect?

Before cataract surgery, your eye doctor performs a painless ultrasound test to measure the size and shape of your eye. This helps determine the right type of artificial lens, called an intraocular lens.

You won’t be able to see or feel the artificial lens. It requires no care and becomes a permanent part of your eye.

The artificial lens does some of the work of eyeglasses or contact lenses. Some of the types of artificial lenses available include:

• Fixed-focus monofocal. This type of lens focuses light to see clearly at one distance. Distance vision is usually the preferred correction, but near or reading vision can be chosen, depending on your preferences. If distance vision is corrected, you’ll need reading glasses for near vision or reading.
• Multifocal or extended depth of focus. These types of lenses have different areas that can help to see various combinations of near, medium and distance. These lenses are like glasses with bifocal or progressive lenses.
• Astigmatism correction, also called toric. If you have significant astigmatism, a toric lens can help correct your vision.
