How To Really Treat Cataract

The opacification of the normal transparent lens is called cataract. The Latin word ‘cataracta’ means ‘waterfall.’ Imagine trying to peer through a sheet of falling water or through a frosted window. In the early stages of cataract development, all that is needed to correct your vision with glasses is a change in prescription. As the cataract develops and begins to affect your lifestyle, it needs to be removed. Cataract surgery, the most commonly performed surgery, is safe and effective in 95 per cent patients with enhancement in vision.

The earliest surgery treatment that began in India was known as ‘couching.’ The sclera was incised and the lens was then dislocated backward into the vitreous and out of the optical axis. This procedure was performed for more than two thousand years until the mideighteenth century. Immense progress in cataract surgery has been made in recent years with the introduction of micro-surgical instruments, microscope and modern surgical techniques like phaco-emulsification.

The Phacoemulsification Technique
During this procedure, the surgeon first creates a small incision with an advanced diamond blade. He/she will then peel off the front layer of the lens capsule. Using ultrasound from small sophisticated instruments, the surgeon breakups the cataract into minute fragments. The instruments then use gentle suction to extract these fragments out of the eye. And an intraocular lens is implanted to replace the natural lens.
