Cataract is the opacity that affects the lens of the eye, which is inherently transparent and located behind the iris, and when the cataract is formed, the natural lens begins to gradually lose its transparency and become opaque, preventing light from passing through it, and then the vision becomes blurred and blurred. It may affect humans at an age. It is one of the most important causes of total or partial blindness in the long run.

For Cataract diagnosis your doctor will perform a comprehensive eye examination to check cataracts and assess your vision, this will include an eye chart test to check your vision at different distances and measure pressure to measure eye pressure. It also uses the most common stress measurement test, where a painful puff of air is used to flatten the cornea and test your eye pressure. Your doctor will put drops in your eyes to make your eyes wider, making it easier to check the optic nerve and retina at the back of your eye for any damage. Other tests your doctor may perform include checking your sensitivity to glare and your perception ofcolors.

Symptoms vary from person to person and the most important symptoms are:
• Progressive weakness of vision without pain.
• Blurry vision with blurred.
• Inability to withstand bright light.
• Lens opacity, generally blurry vision.
• In advanced cases, the color of the eye lens gradually changes to white.

What causes Cataract?
Factors that contribute to the disease include:
• Aging.
• Diabetes.
• Smoking.
• High blood pressure.
• Diseases caused by obesity.

The diagnosis is made by an ophthalmologist by examining the patient’s vision and medical history.

When the disease affects the lens, it can cause partial or total vision loss and the only treatment is surgical intervention, and one of the most important surgical interventions: removing the cataract-affected lens and replacing it with another new, lifelong lens. This process has different ways of different situations.

The effective treatment for white water is to lift the affected lens and replace it with a surgically artificial lens called a lens implant.
A decade or more ago the patient was given time until the water is collected to include all parts of the lens, but now, thanks to medical and technological advances surgical and using modern advanced devices, it is possible to perform the operation at any time the treating physician decides to do so and in agreement with the injured patient, as it is possible to perform cataract lift in both eyes at the same time contrary to what was going on in the past, which is the second operation at least six months after the first operation, of course this depends on the general conditions of the patient, his health condition and other symptoms.

Some patients do not need to use glasses after the surgery, and some of them need, and the review of the attending doctor from time to time remains very important to check the position of the lens or the implanted lenses.
