The eye is like a camera. The natural lens is directly behind the pupil. It focuses on the light entering the retina located behind the eye. It also acts as regulator of the eye and give us a chance to see clearly things near and far.

The lens is composed of a number of proteins and water. When you age, the concentration of the protein can form small lumps and cloud the lens. This is called a cataract, and over time, clouding may become a cause greater and obstruction in our line of vision.

Cataract starts as a harmless thing. Maybe you won’t even notice its existence, except maybe a little blurred vision. Sunlight or bright lights may seem too strong. Cataract once developed, do not require immediate surgery to remove it. Your doctor may suggest some increased aid visual aids, and more powerful bifocal glasses, magnifying glasses or adequate lighting is suitable for you. Cataract eye surgery becomes inevitable when your ability to see is affected significantly and causes serious problems in your vision.

There are many who believe that a cataract is a normal phenomenon associated with aging – but cataract surgery is very popular and otherwise simple and painless way to return to normal vision. It is also one of the most commonly performed eye operation of the United States, which has more than 1.5 million procedures done each year. Ninety percent of the people who have made cataract eye surgery back in their views.

Since cataracts caused by cloudy vision, the basic ideal behind cataract laser surgery is to remove the cloudy lens and replace it with an artificial lens, which is made of silicone and plastic. These lenses are called intraocular pressure of the lens, or IOL. It is a major research and development and production of IOL today, thanks to state of the art IOL available, cataract laser surgery has become easier for physicians and convenient to patients. The different types are available on IOL’s vision correcting IOL, which allows you to see things which are at different distances. Another type of IOL creates obstacles to ultra-violet and blue lights, which according to survey damage the retina.

During cataract laser surgery the natural lens can be replaced by a permanent IOL implant. From the cover surgery to collapse cloudy lens, or cataract, using a process of ultrasound. This process is called phacoemulsification, in which the lens is cloudy, when they are divided is suctioned eye. The second process, called phacofracture sharing is a cloudy lens of the eye was a small eye.
