Apart from regular cataract surgery using rigid and foldable IOLs, the most modern cold phaco system with sonolase technology is also perfected by the doctors and surgeons. Cataract is the opacity of the lens of the eye resulting in blurring vision. It may be congenital, arising from some metabolic disorder, eye disease, exposure to prolonged periods of infrared radiation, injury to the eye or most commonly due to old age.
A cataract is a condition in which the clear lens of the eye becomes cloudy, preventing sufficient light rays from entering the eye and impairing vision. Cataract is not a tumor or a growth over the eye as is commonly feared. It is normally a part of the ageing process and is due to the physical changes taking place in the lens. A common condition among the elderly, cataracts can also be caused by injury, be present at birth or due to illnesses such as diabetes.
The first sign is usually a blurring of vision which cannot be corrected by glasses. Pacification, or clouding, nearly always develops at the edges of the lens and if progressive, impairs vision as it spreads inwards. Other symptoms may include seeing multiple images, poor vision in bright light, seeing a large black spot in front of the eye or haloes around lights.
At present, there is no recognized or effective treatment for cataracts once they become advanced, apart from surgery. Depending on the patients needs, and as long as vision remains satisfactory, surgery is not necessary. However, your surgeon will advise that the cataract be removed when poor vision interferes with your daily activities. Cataract microsurgery is usually highly successful and more than 90% of patients are able to regain good vision. With the removal of the cloudy lens, an artificial lens is needed to substitute its function of focusing light rays onto the retina. This is achieved in one of three ways by special cataract glasses, contact lenses or intraocular implants which are plastic discs inserted into the eye.
Artificial lenses implanted inside the eyeball by surgery have been used for over thirty years with excellent results achieved, particularly. However, occasional complications still exist such as raised eye pressure (glaucoma) and inflammation (iritis). Sight may also deteriorate several months or years after surgery due to thickening of the lens capsule, which is left behind. This condition may be improved either through an operation known as capsulotomy or treatment using the YAG laser. As each patient has special needs and problems, your ophthalmologist will discuss your treatment with you during your consultation.
The two most common types of cataracts are: the cortical or nuclear cataract and a posterior subcapsular cataract. Depending on the type of cataract, a patient will experience different vision problems, but the most common cataract symptoms include:
sensitivity to light or glare
double vision in one eye
poor night vision
needing brighter light to read
Experiencing fading or yellowing of colors.If the cloudiness is not near the center of the lens, you may not be aware that you have a cataract.
At our clinic, different types of diagnosis and treatment facilities are available.
