In the past, eye specialists often waited until the cataract became “ripe” and your vision was very poor before suggesting you had the cataract removed.
Nowadays, with modern surgery the operation is usually done as soon as your eyesight interferes with your daily life. This includes having any difficulties with looking after yourself or others, cooking, driving, getting out and about, being able to read, work or do the things you enjoy.
If you are a driver you must reach the visual standard required by the Department of Motor Vehicles, and it may be necessary to have the cataract removed in order to keep your license.
