Presbyopia is a natural ageing process and affects everyone.
In young eyes the muscles within them contract and relax allowing the lens within to change shape and change focus. The medical terminology for this process is called accommodation.
From around the age of 40+, this process becomes less efficient and results in a loss of accommodation, also known as PRESBYOPIA.
Presbyopia or blurred vision due to age can be improved by wearing bifocal or multifocal glasses or contact lenses. They can take a while to get used to and not everyone can tolerate this form of correction.
The surgical option is to remove the lens within the eye and replace it with a lens capable of focussing at varying distances (a bifocal, multifocal or depth of focus premium lens).
The removal procedure is the same as removing a cataract and as a result, people who have lens replacement surgery do not develop cataracts in later life.
The treatment is called lens exchange or replacement or refractive lens exchange/replacement surgery and other similar variations.
Cataracts are usually age-related and can be in one or both eyes. They can also result from trauma to the eye and some babies are born with them.
The early formation of a cataract can sometimes be seen on examination before the symptoms are problematic. Progress is usually slow and eventually results in cloudy vision because the lens in the eye slowly changes from transparent to opaque.
If you have a cataract you may initially notice that your vision simply isn't as clear as it once was, even when wearing glasses. Over time, colours can fade. Some people liken it looking through a misty or dirty window.
Glasses and contact lenses cannot correct a cataract. Removal of the lens and replacement with a clear lens is one of the most common and beneficial of surgical procedures and it has an excellent safety profile.

Very few people have perfect vision. Most people have a little bit of astigmatism or maybe are a little long or short-sighted. Glasses or contact lenses can help correct our vision but relying on them to see is not for everyone.
Not everyone can tolerate contact lens wear, and glasses get scratched, they also change the perspective of the eye area, magnifying lines or making the eye look smaller. It isn't possible to wear glasses and sunglasses at the same time and life can be difficult if you lose or forget your glasses or enjoy hobbies where they steam up, get wet or fall off.
Providing the eye is healthy, long-sightedness (hyperopia) short-sightedness (myopia) and astigmatism can all be corrected with a short procedure;
