What are cataracts?
Cataracts are an opacity or discoloration of a structure called the lens which is found inside the eye behind the iris (the coloured part of the eye) and pupil. Cataracts do not grow across the front of the eye as commonly thought.
Cataracts are most commonly caused by ageing – just as your skin changes as you age so does the lens of the eye. The lens is usually clear like a glasses lens at birth, and becomes more hazy and yellowed throughout your lifetime. Eventually it becomes more difficult to see through the lens, causing blurry vision and increased problems with glare. This may not be as noticeable as you would think because the cataract forms slowing over many years, allowing a person to get used to their vision not being as clear as it once was. For many people, one of their first symptoms of cataract is increasing difficulty reading small print, even when wearing their glasses. It is common to have some degree of cataract by age 60 even though the cataract may be having no impact on day to day vision at this time.
Cataracts are treated by surgical removal by an ophthalmologist (eye surgeon). The surgery is usually completed under local anaesthetic and patients go home the same day. The majority of patients have excellent results, and often find they no longer rely on glasses as much after the surgery.
