What is Cataract?

A cataract is a condition in which the normally clear lens of the eye becomes cloudy, making vision appear blurry or hazy—similar to looking through a fogged window.

Cataracts usually develop slowly and are one of the leading causes of vision impairment worldwide, especially in older adults.

Types of Cataract

Cataracts are classified based on their location and cause:

1. Nuclear Cataract

Affects the center of the lens and mainly impacts distance vision.

2. Cortical Cataract

Develops in the outer layer of the lens and causes glare and light sensitivity.

3. Posterior Subcapsular Cataract

Forms at the back of the lens and affects reading and vision in bright light.

4. Congenital Cataract

Present at birth or develops in early childhood.

5. Secondary & Traumatic Cataract

Occurs due to eye injury, medical conditions, or after eye surgery.

Common Lens Disorders

Apart from cataract, several other conditions can affect the eye lens:

1. Presbyopia

Age-related loss of near vision due to reduced lens flexibility.

2. Aphakia

Absence of the natural lens, usually after cataract surgery or injury.

3. Lens Dislocation (Ectopia Lentis)

Lens shifts from its normal position.

4. Posterior Capsule Opacification (PCO)

Clouding of the lens capsule after cataract surgery.

These conditions can impact vision clarity and may require medical or surgical treatment.

Symptoms of Cataract & Lens Disorders

Symptoms may develop gradually and worsen over time:

• Blurred or cloudy vision
• Difficulty seeing at night
• Sensitivity to light and glare
• Halos around lights
• Fading or yellowing of colors
• Frequent changes in glasses number
• Double vision in one eye

If you experience any of these symptoms, it is important to consult an eye specialist promptly.

Causes of Cataract & Lens Disorders

The most common cause is aging, but several other factors can contribute:

• Aging-related protein changes in the lens
• Diabetes and other systemic diseases
• Eye injuries or trauma
• Long-term steroid use
• Excessive UV exposure
• Previous eye surgeries
• Genetic factors

These factors can lead to structural changes in the lens, affecting vision.

Risk Factors

You may be at higher risk if you:

• Are above 50 years of age
• Have diabetes or hypertension
• Smoke or consume alcohol
• Have prolonged sun exposure
• Have a family history of cataract

Diagnosis of Cataract & Lens Disorders

At ASG Eye Hospitals, a comprehensive eye examination is performed to diagnose lens disorders.

Diagnostic Tests Include:

• Visual acuity test
• Slit-lamp examination
• Retinal examination
• Refraction test

These tests help determine the severity and best treatment approach.

Treatment Options for Cataract & Lens Disorders

1. Non-Surgical Management

In early stages:

• Prescription glasses
• Improved lighting
• Anti-glare lenses

2. Cataract Surgery

The most effective treatment for cataract is surgical removal of the cloudy lens and replacement with an artificial intraocular lens (IOL).

Advanced Surgical Options at ASG:

• Phacoemulsification (laser-assisted surgery)
• Premium IOLs (multifocal, toric lenses)
• Micro-incision cataract surgery

Cataract surgery is safe, quick, and highly successful in restoring vision.

Complications if Left Untreated

Ignoring cataract or lens disorders can lead to:

• Severe vision impairment
• Increased risk of falls and accidents
• Glaucoma (in advanced cases)
• Permanent vision loss

Early treatment ensures better outcomes.

Cataract in Children

Though cataracts are common in older adults, they can also occur in children (congenital cataracts). Early detection is critical to prevent lifelong vision problems.

Prevention & Eye Care Tips

While cataracts cannot always be prevented, you can reduce risk by:

• Wearing UV-protective sunglasses
• Maintaining healthy blood sugar levels
• Avoiding smoking
• Eating a balanced diet rich in antioxidants
• Getting regular eye check-ups
