Cataract is the clouding of the natural lens of the eye. This results in blurring of vision and if left untreated it can even cause blindness. Cataract surgery is the commonest surgery performed in the world. It is also the most safely performed operation with the highest success rate.
Cataract is the clouding of the natural lens of the eye. The hitherto clear lens that allows light to pass through and focus a sharp image on to your retina, now becomes opacified, hindering the passage of light and hence debilitating your vision. Cataract surgery is removal of this opacified lens (cataract) and placement of an artificial lens, also known as intraocular lens (IOL) to restore your vision.
Children could be having cataracts right from birth. We refer to them as congenital cataracts. Fortunately, they are rare occurrences. Like many others, you may not even be aware that your child is having a cataract because children generally never complain of poor vision. It might be even more difficult when the child of suffering from poor vision due to cataracts in both eyes. Therefore, only the ophthalmologist, who puts the child through a complete eye examination, will be able to help you with the right assessment.
Cataract surgery is known to humanity since ages. The first documented cataract surgical procedure dates back in the fifth century BC. Today, the advanced and sophisticated technologies used in cataract surgery have made it incredibly useful and virtually painless.
Cataract is a very common eye problem and affects millions of people worldwide. If your vision is hampered due to cataract, your eye specialist will ask you to undergo surgery. Although the term ‘cataract surgery’ may sound scary at first, with the help of advanced technology and a qualified and skilled surgeon, it can improve your vision instantly.
Due to the ageing process, cataract develops either in one eye or both. This clouding occurs in the natural lens of the eye. Apart from age, other factors contributing to this condition are genetic disorders, past eye surgery, diabetes, uveitis, eye trauma, etc. Basically, cataract occurs due to protein denaturation which prevents light from passing through the natural lens of the eye and thereby causing hazy vision.
The natural lens of the eye helps to focus light on the retina for clear vision. However, our clear natural lens begins to become cloudy over a period of time and this is known as cataract formation. It is a degenerative condition that interferes with vision. This impairment of vision affects the quality of life. Generally, cataract formation is age-related, but very rarely this condition can occur at birth or in younger people as well. If left untreated,
Cataract, a very common eye condition affects many people worldwide. Generally, cataracts are found in people older than 40 years of age. It is basically clouding of the eye lens due to ageing. But this eye condition affects vision and thereby the quality of life.
Cystoid macular oedema is a painless condition which affects the macula – the central part of the retina (Figure 1.1 and 1.2). This condition occurs when fluid collects in the tissue at the back of the eye, including the area responsible for our central vision. This accumulation of multiple pockets of fluid as cysts in the macular area, is known as cystoid macular oedema.
