Ophthalmology Department at Zydus Hospital offers state of the art medical and surgical care encompassing Adult and paediatric ophthalmology. Our Ophthalmology unit performs almost all Ophthalmic procedures using most recent surgical and reconstructive techniques. As a part of multi-disciplinary approach the department also treats secondary eye problems related to some systemic disease like diabetes, hypertension, autoimmune disease etc.
We have a team of highly experienced surgeons which is supported by most advanced medical equipment and techniques.
A cataract is a clouding of the eye’s lens, which lies behind the iris and the pupil. It can affect one or both eyes. Often it develops slowly. It is one the leading cause of vision impairment.
Cataracts can be classified by anatomical location within the lens, degree of clouding of the lens, or by the cause of the cataract.
Some of them are :
A subcapsular cataract occurs at the back of the lens. People with diabetes or those taking high doses of steroid medications have a greater risk of developing a subcapsular cataract.
A nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging.
A cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs in the lens cortex, which is the part of the lens that surrounds the central nucleus.
Congenital cataracts, which are present at birth or form during a baby’s first year, are less common than age-related cataracts.
Secondary cataracts are caused by disease or medications. Diseases that are linked with the development of cataracts include glaucoma and diabetes. The use of the steroid prednisone and other medications can sometimes lead to cataracts.
Traumatic cataracts develop after an injury to the eye, but it can take several years for this to happen.
There ac be various factor behind development of cataract, some of the most common reasons are:
A cataract develops slowly and at first has little effect on your vision. You may notice that your vision is blurred a little, like looking through a cloudy piece of glass. As the disease progresses your vision gets impaired and my cause total blindness.
Apart from blurring vision other symptoms may include faded colors, halos around light, trouble with bright lights, and trouble seeing at night. This may result in trouble driving at night or reading.
A cataract can be diagnosed easily through a proper eye examination.
Phacoemulsification is the most common surgical procedure to remove cataract. In this procedure an ultrasound device is used to break the clouded lens, which is then removed. A new intraocular lens is inserted immediately after removing the emulsified lens.
Extra Capsular Cataract surgery is another method of removing cataract. It is generally used for advanced cases of cataracts where it is difficult to break the lens. The lens is removed in one piece which is replaced by the new IOL. It generally requires a larger incision then phacoemulsification.
