A cataract is a clouding of the eye’s natural lens. A normal lens is clear and lets light pass to the back of the eye (the retina). If the lens becomes cloudy, it is called a cataract. Over time, it may become cloudier, making it harder to see.
Cataract formation only affects the lens of the eye, none of the other important structures such as the cornea, iris, retina or optic nerve.
Symptoms you may notice include:
• your vision may be a little blurred, like looking through a cloudy glass
• light from the sun or a bulb may seem bright or glaring
• when you drive at night, oncoming headlights may cause glare or haloes
• colours may not appear as bright as they used to
• your glasses prescription may change
• you may have double vision
Removal of a cataract is the most common eye operation and one of the most common surgical procedures performed in India today. It has a high rate of success due to the modern methods used.
Cataract surgery is a safe, effective way to improve your vision. Cataract surgery is a microsurgery, a tiny incision (3mm) is made on the side of the cornea. Through this insertion the doctor inserts a tiny probe, using high frequency sound waves (phacoemulsification) the cataract is broken up & removed from the eye via the fine probe. The membrane that surrounds the natural lens of the eye is left intact. This membrane (capsular bag) provides support for the new, intraocular lens (IOL).The IOL is made of plastic, silicone or acrylic. The IOL is folded and inserted through the same micro- incision; it unfolds in the eye into its permanent position. Because of the size and location of the incision, stitches are rarely needed, and the eye heals rapidly.
