A cataract is a clouding or development of opacity in the natural intraocular crystalline lens. The crystalline lens is the one that focuses the light entering the eye into the retina so that we can see clearly.
In the initial stages of cataract, the symptoms are mild and sometimes not at all noticed by patients esp if the cataract is developing gradually in both eyes or if only in one eye and the other eye lens is clear.
Cataract development is multifactorial.
Causes of age-related cataract1. There is an accumulation of lens material over the existing crystalline lens which leads to compaction and stiffening of the lens.2. Abnormal changes in lens protein lead to loss of transparency. Due to the accumulation of fibers and or changes in lens protein of different parts of the lens we have different types of cataracts like nuclear, cortical, post, and anterior subcapsular.
3. Pigmentation of lens protein leads to a change in color of the lens from transparent to yellowish to yellow to brine scent to dark brown to black cataract.
In the subsequent series wherein we shall see different types of cataracts I will discuss in detail about them.
This is a million-dollar question literally and figuratively. There is no medical line of treatment to treat or prevent the development or progression of cataracts. No spectacles or contact lenses can treat cataracts. The only line of management is the surgical removal of the cataractous lens and implantation of the artificial intraocular lens, irrespective of the type or mode of cataract surgery used. In the subsequent series, I shall discuss different types of cataracts and their causes.
