What is cataract..?

 What is cataract..? A cataract is an eye disease which causes a clouding of the lens inside the eye; normally the lens is clear, but as cataract develops it becomes cloudy and opaque. This can be likened to a glass that has been through a dishwasher too many times and your vision appears as if you are looking through a dirty windscreen or frosted glass. As the cataract becomes more mature it can be seen as a clouding of the eye which reduces the ability of light to pass through it which causes a decrease in vision.

The lens of the eye works by focusing the rays of light which enter the eye onto the retina which is the light-sensitive tissue located at the back of the eye. The parts of the eye in front of the retina, which include the lens, must be clear and transparent in order to allow light to reach the retina unhindered. As the light reaches the retina a chemical reaction takes place which generates tiny electrical impulses which are then transmitted to the brain where they are processed and translated into what we all perceive as sight.

In a normal healthy eye, the light passes through the clear and unclouded lens to the retina located behind. In the case of a cataract, the lens is clouded which hinders the passage of light to the retina and so the resulting image hitting the retina will be blurred and thus the vision itself will also be blurred in exactly the same way. The extent to which the vision will be disturbed is dependent upon how severely the lens has become clouded by cataract.

The most common cause of cataract is age-related cataract and this form are usually referred to as senile cataract. Other causes include; diabetes, traurma induced by injury, congenital cataract and drug induced. Cataract is very common among the elderly; by the age of eighty, more than fifty percent of all Americans either have at least some degree of cataract forming, or have already undergone cataract surgery. By the age of ninety-five, virtually all will have experienced the same problem.

A cataract can occur in one or both eyes and people with cataract in one eye will eventually usually develop a cataract in the other eye as well. A cataract is not infectious nor contagious and cannot be transmitted from one eye to another eye or from one person too another person. Impaired and clouded vision are the only noticeable effects of a cataract and they are neither painful, itchy or cause any redness or swelling of the eye.

Different types of cataract

A cataract can affect different parts of the lens of the eye and, depending upon which area, or areas, are affected, they are given different names to identify them. Your eye specialist or ophthalmologist will examine your eyes and determine whereabouts in your lens the cataracts originally started to form and your accompanying symptoms will be dependent upon which type of cataract you have.

Some cataract begin to form around the edges of your lens and then grow in a spoke-like pattern, very similar to the spokes on a bicycle wheel. This type of cataract is referred to as cortical cataract and the main symptoms of this type of cataract are glare sensitivity and starting to see a ring or halo around lights. These symptoms can be especially noticeable when driving at night and the oncoming headlights shining in your eyes bother you more than they did before, or when the sun is low in the sky.

Another type of cataract can be diagnosed by the middle of your lens turning a yellowish-brown colour and the lens becoming harder. This type of cataract is referred to as nuclear cataract and the usual symptoms are blurred vision.

Some cataract occur when grainy cells get in between the back of the lens and the eye capsule and are referred to as posterior subcapsular cataract. The usual symptoms associated with this type of cataract are that you begin to experience bad glare from lights and posterior subcapsular cataract can quite often develop in younger people.

It is also possible to have a combination of any of these three different types of cataract and, if you have combination of different types, it is then referred to as a mixed cataract. Almost one-third of all cataract cases have a mixture of different types and so fall into this category.

Who is at most risk of developing a cataract..?

Cataract are extremely common and can develop at any age, but as you get older the chances of developing a cataract increase greatly. In the early stages it probably won't bother you that much, but the sooner treatment is started the easier it will be to clear. Your chances of developing a cataract are greatly increased if you smoke or if you spend a lot of time in the sun. Other risk factors include; diabetes, the prolonged use of steroidal type drugs, having high blood pressure and/or heart disease, getting too dehydrated at some point in your life i.e. having severe diarrhea can make you very dehydrated, or having a history of cataracts running in your family.

Cataract treatment

Previously, the only way to clear a cataract was surgery; where the lens of the eye was surgically removed and then replaced with a new man-made replacement. But now there is a new and natural alternative to surgery using a simple course of N-Acetyl-Carnosine (or NAC for short) eye drops. The NAC eye drops are applied hourly throughout the day and immediately go to work to dissolve the cataract and return the lens back to full clarity once again; thus restoring normal vision.
