Cataracts


Cataract refers to the opacification of the natural crystalline lens of the eye responsible for bringing rays of light to a focus on the fovea, the most important part of the human retina.

Cataract formation is a part of the natural ageing process that every human being must go through. Certain conditions can result in early development of cataracts.
These include :

1.) Birth defects or pregnancy related illness
2.) Viral infections
3.) Systemic diseases present either at birth(such as galactosemia) or acquired later in life(such as diabetes mellitus)
4.) Use of steroids in any form
5.) Uveitis
6.) Injury to the eye by blunt or sharp objects
7.) Nutritional deficiency.


 

These are special situations and may warrant additional treatment. The surgical outcomes in these conditions are not as predictable as they are in age related cataracts

The only effective treatment today issurgical removal of the opacified natural crystallinelens and replacing it with a clear, biocompatible artificial intraocular lens. This is performed currently using the 'phacoemulsification procedure'. Regardless of whether 'laser technology' is used, phacoemulsification is the ultimate step in the surgical procedure used to remove cataracts.

The choice of intraocular lenses available today is vast. The latest type of lenses obviate the need for glasses(or at least bring it down to a minimum) and are known as multifocal lenses or multifocal-toriclenses(which incorporate a correction for cylindrical lenses as well). A variety of lenses(such as toric or trifocal lenses) are available to cater to everyone's individual requirements. The eye surgeon will advise you regarding the most suitable lens for your eye after performing certain tests.

A comprehensive eye check up is necessary prior to cataract surgery to make sure that there is no other co-existent disease that can account for the drop in vision or your complaints.

The latest technology renders cataract surgery very safe and predictable. The instruments currently available ensure total control over the phacoemulsification procedure. In some cases, a change of strategy is required on table.To view videos of how this technology
