To see clearly, all parts of the eye need to function properly. Poor eyesight maybe due to a number of reasons, and cataracts maybe one of those reasons.
The anatomy of the eye is similar to that of a camera. several parts are responsible for the clarity of the image you actually see, and all need to be working properly.
Within the eye, between the vitreous and the iris, is a crystalline lens which is responsible for ' fine tuning' our vision, so that images are clear and focused.
Ordinarily the lens is clear. When the lens loses its clarity and becomes cloudy this is called a cataract.
Some babies are born with cataracts and these are called ' congenital' cataracts. The most common type however are age related and develop in middle age and later years.
Cataracts are not always apparent without the use of diagnostic equipment and unless caused by trauma to the eye, usually form over a number of years.
The cataract on the left is clearly visible because of its density (advanced stage) and because the pupil has been dilated.
Over a period of time, images become ' washed out'. Colours are less vibrant and vision becomes more blurred. Some people experience double vision and it is common to experience glare from bright lights, which can cause problems for drivers.
Spectacles cannot correct the problems caused by cataracts, however for non drivers whose quality of life is uneffected, an operation may not always be necessary.
Mr Aggarwal will discuss all options with you, and will make recommendations in conjunction with your lifestyle.
Patients usually gain enormous benefits from undergoing a cataract procedure. Mr Aggarwal carries out Advanced Refractive Cataract Surgery combining 'Refractive Surgery' with 'Cataract Surgery'. The cataract procedure removes the opaque lens and the refractive procedure reduces or eliminates astigmatism and then replaces the lens with a multifocal style lens. This reduce or eliminates the need for glasses afterwards to ensure the best possible outcome for his patients.
