All About Cataract

Cataract is the clouding of ones eye's natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over the age of 40 and are the most common cause of blindness in the world. In fact, there are more cases of cataracts worldwide than there are of glaucoma, macular degeneration and diabetic retinopathy combined.
What are the different types of cataract?
The different types of cataract include:

• Sub capsular cataract: It occurs at the back of the lens. Diabetic people or those who are taking high dosage of steroid medications have a greater risk of developing a sub capsular cataract.
• Nuclear cataract: It is formed deep in the nucleus of the lens. Nuclear cataracts are usually associated with aging.
• Cortical cataract: It is characterized by the white, crescent shaped opacities that begin from the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs mainly in the cortex of the lens, which is that part of the lens which surrounds the central nucleus.

What are the signs and symptoms of cataract?

A cataract starts out small and at first and has little effect on the vision. The vision is blurred a little, similar to looking through a cloudy piece of glass. A cataract may make light from the sun or a lamp too bright or glaring. It may also come to notice that the oncoming headlights during the night causes more glare than before. Colors may not appear as bright as they once did.

What causes cataract?
The lens inside the eye works much like a camera lens, focusing light onto the retina for clear vision. It will also adjust the eye's focus, which lets us see things clearly both up close and far away.
The lens is mainly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and let’s light passes through it. But as we age, some of the protein may combine together and start to cloud a small area of the lens. A cataract may grow larger and cloud more on the lens over time, making it harder to see.
How is cataract treated?
Cataract surgery is very successful in restoring vision. During surgery, the surgeon will remove the clouded lens and in most cases replace it with a clear, plastic IOL. New and advanced IOLs are being developed with time to make the surgery less complicated for surgeons and the lenses more helpful to patients.

Open Your Eyes To Clear Vision

The lens of the eye is mainly composed of water and proteins. As we get older these proteins may begin to come together and cloud the lens. This clouding is called the cataract. Cataract surgery is the removal of the affected cataract from the eye and insertion of an artificial lens.

Before surgery you will be given eye drops to dialate your pupil. Area around eye will be washed and cleansed. Local anasthetic will be injected around your eye. You may also be offered a sedative. Most cataract surgeries last for more than one hour.

Types of cataract surgeries:
There are two types of cataract surgeries. The first procedure is phacoemulsification. In this procedure, the surgeon looks through an operating microscope and makes 3 small incisions less than one inch long in or near the cornea. An opening is made through the capsule of the lens and an ulstrasound probe is used to break the cloudy lens into tiny fragments. These fragments are vaccumed out through the incisions. Then an artificial intraocular lens is inserted. Intraocular lens is made of plastic, silicone or acrylic compounds. Stiching are generally not necessary in this procedure.

Another type of cataract surgery is called the Micro Phaco Cataract Surgery. It is nicknamed as pinhole surgery, as the incision size was very small. Faster healing and quicker rehabilitation is the main advantage of Micro Phaco Cataract Surgery. This surgery is ideally suited for people who want to start working soon after surgery. As this procedure is safer than conventional Cataract Surgery, patients with higher risk profile like diabetics and nephrology ideally opt for this procedure and is also the best option for complicated eye surgeries.

Generally cataract is seen in aged people.

When you become older, the lens of your eye becomes cloudy. It is because of the protein loss in the eye. But, no one feels that they have cataract, as it grows slowly. Cataract never blocks the vision at the starting stage. But when age passes by, it become dangerous and person who is having cataract lose the vision.

Aging is the main cause for cataract. Cataract is classified into 4 types :  

Secondary Cataract :- It may be developed as a result of medical conditions like diabetes or exposure to drugs.
Congenital Cataract :-  It may be developed as a result of medical conditions like diabetes or exposure to drugs.
Traumatic Cataract :- Injuries and infections may cause congenital cataract.
Age Related Cataract :- It may be developed as result of aging.

Symptoms :

1. Problems of glaring
2. Blurry or Cloudy vision
3. Frequent and sudden changes in prescription
4. Problems while you drive at night
5. Double Vision

You can’t live a normal life without sight. So, obviously you need a treatment for this. Cataract surgery is the effective treatment for cataract. Macro phaco cataract surgery, YAG Laser for after cataract and Microincision cataract surgery (phacoemulsification) are the different cataract surgery.

MacroIncision Cataract Surgery :- In Phacoemulsification surgery, for breaking the hard cataract into tiny pieces, ultrasound power is used. Then they are taken out through a small 1.5-2.8mm incision. A foldable lens of the required power is then implanted. The soft construction allows the lens implanted to be folded for insertion through a 1.5 to 2.8mm microincision. Once in place, the lens unfolds to its regular size of 6 mm.

Advantages of this surgery are :

* Final glasses can be prescribed within two weeks
* Minimum curvature changes occur in the eye following surgery
* Early visual rehabilitation for the patient
* Post surgery, the wound is very secure

Micro Phaco Cataract Surgery :- The procedure is same as that of the macro incision cataract surgery. But this surgery has lot of advantages over macro incision cataract surgery. Incision size is reduced by 40%. This heals very quickly. Main intention of this surgery is patient safety. This surgery is nicknamed into “pinhole surgery” .

YAG Laser for after Cataract :- YAG LASER produces a concentrated beam of light that can focus on the iris or any thick membrane behind the intraocular lens. This laser beam can create a smooth, fine opening of desired size in these structures without affecting other sensitive parts of the eye. Laser surgery is painless and safe with few complications. Special eye drops are put in the eyes to numb them. A small contact lens is placed on the eye to direct the laser light on to the desired site. This surgery takes only few minutes.
