Cataract surgery is done to remove the natural lens in the eye by separating cataract from the lens capsule. Cataract is the cloudy part inside the eye and the lining around it is called lens capsule. Due to certain metabolic changes, cataract is formed causing loss of transparency in the eye. This leads to serious eye sight problems and development of glare. There are different types of cataracts: subcapsural cataract that forms at the back of the lens, nuclear cataract which is seen in the centre and cortical cataract formed around the lens.
Eye for details
The first extracapsular cataract extraction was done in 1747 by French ophthalmologist Jacques Daviel
Certain historic evidences and documentation suggest that Egyptians knew about the procedure way back in the 5th century
The word cataract has its root in Latin word cataracta which means waterfall.
Cataract removal surgery is a common eye surgery and is a safe procedure performed by ophthalmologists under local anaesthesia. It is done for about an hour or a little more. There are different cataract surgeries performed by ophthalmologists:
Phacoemulsification surgery which is a common cataract surgery and is also called small incisions category where small cuts are made.
Standard extra capsular cataract extraction or Standard ECCE where 8mm to 10mm cut is made to the eye and another cut is made to the lens.
In cataract removal surgery, the lens is removed and is often replaced with intraocular lens (IOL) made of clear plastic.
Cataract laser surgery is also gaining popularity where the surgeon uses laser to make an opening in the eye and remove the cataract.
The lens inside the eye is generally clear. It is made up of water and protein. It focuses light on the retina and adjusts eye focus which helps us see things from a distance or close up. As we age, the protein inside lens accumulates and becomes cloudy, affecting our vision. This is called cataract. Besides age, diabetes, sun rays, hypertension, eye injuries, over-weighing and genetic reasons also lead to cataract. Cataract cannot be ignored because it causes loss of eyesight and difficulty in facing bright lights. This makes cataract surgery important. Also, it is wiser to opt for cataract surgery at the earliest to avoid further complications to the eye. These complications cause problems affecting work, family life and driving.
