Temporary measures to improve your vision can be taken when symptoms of cataract begin to appear. These include strong bifocals spectacles, magnification lenses, and brighter spotlights. Eventually cataracts will progress, to seriously impair your vision and affect your daily life. This is the time to consider cataract surgery. You do not have to accept poor vision as an inevitable fact of ageing. Cataract surgery is a common, relatively painless procedure to help improve your vision.
Cataract surgery is very successful in restoring vision. Nine out of 10 people who have cataract surgery regain very good vision, somewhere between 20/20 (6/6) and 20/40 (6/12), as long as there are no other conditions such as diabetes or macular degeneration. During surgery, the surgeon will remove your clouded lens with a machine that will break up and vacuum your old lens. He will then replace it with a new clear, plastic intra-ocular lens implant ("IOL"). This stays inside your eye and does not have to be changed or replaced, unless there are late complications such as dislocation eg caused by blunt trauma after surgery.
New lens implants, or "IOL"s, are being developed all the time to make the surgery even safer, for surgeons and patients. Presbyopia-correcting IOLs, or "Premium IOLs", potentially help you see at most distances, not just one, and may eliminate the need for glasses for most people. Some may still need glasses for fine print.
