The lens that is implanted in your eye is usually designed to give you clear distance vision without needing glasses. Sometimes this is not quite achieved and you will need a pair of distance glasses to fine tune the focus and get the best possible distance vision. Because the lens implant is not always able to provide in-focus near vision, many people will need to wear reading glasses after the operation and usually this will be a different pair than you had before the operation. In most cases an eye test called a refraction, will be done 4 to 6 weeks after the operation. This may be done by an optometrist in the hospital or you can see your own usual optometrist. If you had a multi-focal lens implanted, you may not require glasses as this can provide clear vision in the distance and up close most of the time.
