Cataracts: Types, Diagnosis and Treatment

Cataracts are a leading global cause of blindness, gradually clouding vision and impeding daily tasks. When ignored, cataracts can disrupt focused light and cause blurred vision, similar to looking through a foggy windshield. Early detection is key for eye conditions like cataracts as it allows for effective sight-restoring treatments. 

Read on as Six One Six Vision Center discusses the types of cataracts and the ways to diagnose and treat these eye problems.

Types of Cataracts

There are several types of cataracts you should know about.

• Nuclear sclerotic cataracts – These cataracts form deep in the nucleus of the lens and are typically associated with aging. Symptoms may include a yellowish-brown tinge to your vision.
• Cortical cataracts – Developed in the lens cortex, these cataracts are characterized by a wedge or spoke appearance. Common symptoms include difficulty with glare and contrast.
• Posterior subcapsular cataracts – These occur at the back of the lens and often affect your reading vision, reduce your vision in bright light and cause glare at night.
• Congenital cataracts – These are present at birth or form in childhood. Often small, they may not affect vision. If they do, removing the lens may be needed.

The Diagnosis of Cataracts

Here’s where eye care comes into play. Proper diagnosis of cataracts requires regular, comprehensive eye exams. These involve specialized tests such as:

• Visual acuity test – This common eye chart test measures how well you see at various distances.
• Dilated eye exam – Your eye professional places drops in your eyes to widen the pupils and examine the lens for signs of cataracts.
• Tonometry – This test measures the pressure inside your eye.

Treatment Options

Non-surgical options involve updated eyewear, better lighting and magnifying lenses for mild vision issues. For more advanced cataracts, the following cataract surgery is required. This involves:

• Phacoemulsification – Dissolving the cloudy lens with ultrasound waves
• Intraocular lens (IOL) implantation – Replacing the natural lens with an artificial one after removal
• Laser-assisted cataract surgery – The surgeon may choose to use laser technology for precise incisions and lens fragmentation.
