A cataract is a clouding of the eye's naturally clear lens. Your eyesight gets blurry, like looking through a frosted window.
This vision simulator demonstrates how eyesight changes when you suffer from cataracts and other vision disorders, such as presbyopia and astigmatism. It also shows how you can improve your vision with cataract surgery. The images simulate the postoperative visual results that can be achieved with different types of intraocular lenses (IOLs).
The visual quality provided by the different IOL types at different light conditions depends on the characteristics of the IOL. It also depends on many individual patient factors such as: the general health of your eye, the individual healing time and adaptation of the brain to the new conditions.
This visual demonstration is meant to give you a rough idea of what to expect depending on what IOL you chose. Results vary individually from person to person and cannot exactly be predicted after the surgery.
