Cataract Surgery
What are cataracts?
A cataract is a clouding of the lens in the eye that may reduce your vision. The lens becomes more opaque and is therefore less able to transmit light rays onto the retina. The image on the back of the eye is then blurred. The structure of the lens also changes as the lens becomes less transparent. Often both eyes are affected.
Different types of cataract
There are different types of cataract, some of which are due to rare diseases or as a result of local eye injuries or inflammation.
However, the two main types are:
Senile (age-related) cataracts - the most common type
Congenital (present at birth) cataracts - which are relatively rare but important to diagnose early since vision and 'seeing' have to be learnt very early in infancy (cataracts present at birth stop the eye from learning to see and can cause blindness even if removed later in life)
Symptoms
You may get one or more of the following symptoms:
A worsening of your vision which may make you feel like your vision is cloudy, fuzzy or filmy spots in your vision glare.
Halos from lights or the sun - this may be severe, and you may also have difficulty driving at night.
Double vision.
Difficulty in telling the difference between colours, especially shades of blue.
Frequent changes in glasses prescription as eyesight deteriorates.
Second sight - your close-up vision and reading may improve temporarily as the lens changes shape
Cataract Surgery
Cataract surgery is very successful in restoring vision. In fact, it is the most frequently performed surgery in Europe, with millions of cataract surgeries done each year. Nine out of 10 people who have cataract surgery regain very good vision, somewhere between 20/20 and 20/40.
During surgery, the surgeon will remove your clouded lens, and in most cases replace it with a clear, foldable intraocular lens (IOL). New IOLs are being developed all the time to make the surgery less complicated for surgeons and the lenses more helpful to patients.We use in all our centres the most advanced IOL's on the market.
