When you are deciding whether to have surgery, you may find it very helpful to evaluate the effect that vision loss from a cataract has on your life. Your doctor may ask you to complete a questionnaire regarding the effect of the cataract on your daily activities.
If you already have some vision loss that cannot be corrected by cataract surgery, your doctor may do a low-vision evaluation to help find ways for you to make the most of your remaining vision and to keep your quality of life.
