Cataracts

What are cataracts?

A cataract is the clouding of the eye’s lens, which is a transparent structure behind the iris that helps focus light onto the retina. As we age, the lens can become less flexible and start to develop cloudy areas. These cloudy areas, known as cataracts, can interfere with vision, causing it to appear blurry or hazy.

What causes a cataract?

While age is the most common risk factor, other factors can contribute to the development of cataracts, including:

• Diabetes: High blood sugar levels can accelerate cataract formation.
• Eye injuries: Trauma to the eye can lead to cataract development.
• Certain medications: Some medications, such as corticosteroids, can increase the risk of cataracts.
• Exposure to ultraviolet (UV) radiation: Excessive exposure to sunlight can contribute to cataract formation.
• Smoking: Smoking can damage the lens and increase the risk of cataracts.

It’s important to note they are NOT caused by eye strain, and they are not a cancer or a tumor.

How do I know if I have a cataract?

As a cataract grows, it can cause a variety of symptoms, including:

• Blurred or hazy vision
• Faded colors
• Double vision
• Sensitivity to light
• Difficulty with nighttime driving
• Frequent changes in eyeglass prescriptions

What are the best cataract treatment options?

Surgery is the best treatment. During the procedure, the cloudy lens is removed and replaced with an artificial lens called an intraocular lens (IOL). Today’s cataract surgery is a minimally invasive procedure that typically involves a tiny incision (about three millimeters; less than ⅛ inch), no stitches, and is performed under local anesthesia. The surgery usually lasts less than 15 minutes.

There are several types of IOLs available to use in surgery, including:

• Monofocal IOLs: These lenses correct vision for one specific distance, such as far vision or near vision.
• Multifocal IOLs: These lenses can correct vision for multiple distances, reducing the need for reading glasses or bifocals.
• Toric IOLs: These lenses can correct astigmatism, a common eye condition that causes blurred vision.

Recovering from cataract surgery

Cataract surgery is usually a very successful procedure with a high rate of patient satisfaction. Recovery time is typically short, and most patients can resume their normal activities within a few days.

If you’re experiencing symptoms of cataracts, it’s important to consult with an eye care professional for an evaluation. Early diagnosis and treatment can help prevent vision loss and improve your overall quality of life.
