What is Cataract?
Cataract is an eye disease in which the natural lens of the eye becomes cloudy, leading to blurred or dim vision. Normally, the lens is clear and helps focus light onto the retina, but in cataract, this clarity is lost—making vision appear hazy, like looking through a fogged glass.
Cataract is one of the leading causes of vision loss, especially in people above 50 years of age, but it is treatable and reversible with surgery.
Cataract: Disease Overview, Symptoms & Treatment
Types of Cataract
1. Nuclear Cataract
- Affects the center of the lens
- Common with aging
- Difficulty in distance vision
2. Cortical Cataract
- Develops at the edges of the lens
- Causes glare and light sensitivity
3. Posterior Subcapsular Cataract
- Forms at the back of the lens
- Affects reading and vision in bright light
4. Congenital Cataract
- Present at birth or develops in childhood
5. Traumatic Cataract
- Caused due to injury to the eye
Symptoms of Cataract
Common symptoms include:
- Blurred or cloudy vision
- Difficulty seeing at night
- Sensitivity to light and glare
- Halos around lights
- Fading or yellowing of colors
- Frequent change in glasses number
- Double vision in one eye
Causes of Cataract
The most common cause is aging, but other factors include:
- Diabetes
- Eye injury
- Long-term steroid use
- Excess UV exposure
- Smoking and alcohol
- Genetic factors
Risk Factors
You are at higher risk if you:
- Are above 50 years
- Have diabetes
- Smoke or drink alcohol
- Have prolonged sun exposure
- Have family history of cataract
Diagnosis
Cataract is diagnosed through an eye examination:
- Vision test
- Slit-lamp examination
- Retina check
- Refraction test
Treatment of Cataract
1. Early Stage
- Glasses or better lighting can help temporarily
2. Cataract Surgery (Best Treatment)
- Cloudy lens is removed
- Artificial lens (IOL) is implanted
Advanced Options:
- Laser cataract surgery
- Phacoemulsification
- Premium lenses (multifocal / toric)
Surgery is safe, painless, and takes 10–20 minutes.
What Happens if Cataract is Not Treated?
- Severe vision loss
- Difficulty in daily activities
- Risk of falls and accidents
- Possible complications like glaucoma
Prevention Tips
- Wear UV-protected sunglasses
