Cataract Surgery At A Glance

Cataract is a clouding of the eye’s lens, the part of the eye responsible for focusing light and producing clear, sharp images. A cataract occurs when the crystalline lens of the eye becomes cloudy or opaque as a result of age, illness or trauma. This cloudiness can interfere with the eye’s natural ability to direct light and focus an image on the retina. As a result, individuals with cataracts frequently experience a loss of vision.

The most common cause of cataract is the deterioration of the normal structure within the lens of the eye with age. There may be another cause like diabetes, kidney disease, glaucoma, smoking, eye injuries, infection and inflammation inside the eyes. Prolonged use of certain medication cans also let to cataract formation.

Common symptoms are blurry vision, colors seems faded, glare, poor night vision, double vision, frequent prescription changes in the eye wear etc. adults over the age of 40 should schedule routine eye examination on an annual basis to determine whether cataract or other eye disorders are present.

A thorough examination by an ophthalmologist or qualified eye care professional usually includes:

• A visual acuity test to measure clarity at various distances
• Pupil dilation to examine the lens and retina for other eye problems.
• Tonometry, a standard procedure to measure fluid pressure inside the eye.

Patients with cataract often experience the following symptoms:

• Blurring of vision
• Glare or sensitivity of light
• Double vision in one eye
• Frequent changes in eye glasses prescription
• Difficulty in reading in low light
• Declined night vision
• Fading colors

Types of cataract

• Secondary cataract:

Cataract can form after the surgery for other eye problems, such as glaucoma. Cataract also can develop in people who have other health problems, such as diabetes. Cataracts are sometimes linked to steroid use also.

• Traumatic cataract:

Cataract can develop after an eye injury, sometimes years later after the injury also.

• Congenital cataract:

Some babies are born with cataract or develop them in early childhood, often in bothh eyes. These cataracts may be so small that they do not affect the vision. If they do, the lense may need to be removed

• Radiation cataract

Cataracts can develop after exposure to some types of radiation.

Causes and risk factors

The lens lies behind the iris and the pupil. It works much like a camera lens. It focuses light onto the retina at the back of the eye, where the image is recorded. The lens also adjusts the eye’s focus letting us see things clearly both up close and far away. The lens is made of mostly 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 clump together and start to cloud a small area of the lens. This is a cataract, over time; the cataract may grow larger and cloud more of the lens, making it harder to see. Researchers suspect that there are several causes of cataract, such as smoking and diabetes. Or it may be the protein in the lens just changes from the wear and tear it takes over the year.

The doctors and staff at the https://www.delhieyecentre.in/ hospital are very experienced and knowledgeable about the cataract and thus successfully treat the patients without any complication. Full attention is given to patients during and after the surgery and seen that the patients are not in any pain.
