WHAT IS CATARACT?
Cataract is a common eye condition characterized by the clouding of the eye’s lens. Normally transparent, the lens becomes opaque when cataract develops, leading to vision loss. Cataracts usually develop due to aging but can also be triggered by various other factors.
SYMPTOMS OF CATARACT
SYMPTOMS OF CATARACT
- Blurred or hazy vision
- Fading or yellowing of colors
- Difficulty seeing at night
- Sensitivity to light and glare
- Double vision or multiple images in one eye
- Frequent changes in glasses or contact lens prescriptions
FACTORS CAUSING CATARACT FORMATION
FACTORS CAUSING CATARACT FORMATION
- Aging: Cataracts are more common in individuals over 60 years old.
- Eye injuries: Physical trauma to the eye can lead to cataract formation.
- Genetic factors: People with a family history of cataracts have a higher risk.
- Other health conditions: Diabetes, high blood pressure, and eye inflammations can increase cataract risk.
- Prolonged exposure to UV rays
- Smoking and alcohol consumption
TREATMENT METHODS
TREATMENT METHODS
Early-stage cataracts can often be managed with glasses or contact lenses. However, as the cataract progresses, surgical intervention may be necessary. Cataract surgery involves removing the clouded natural lens and replacing it with an artificial one. This is generally a safe and effective procedure, with most patients regaining significant vision after surgery. It is also possible to reduce dependence on glasses by using smart lenses implanted during cataract surgery.
MEASURES TO REDUCE CATARACT RISK
MEASURES TO REDUCE CATARACT RISK
- Wear sunglasses: Use quality sunglasses to protect against UV rays.
- Eat healthily: Consuming antioxidant-rich foods can help protect eye health.
- Avoid smoking: Smoking increases the risk of cataracts.
- Regular eye check-ups: Have your eyes checked regularly, especially as you age.
FAQ
Frequently Asked Questions
Cataract surgery involves removing the cloudy natural lens of the eye and replacing it with an artificial lens. It is generally a short and safe operation.
Cataract surgery usually lasts between 15-30 minutes. However, including preparation and recovery time, hospital stay might be slightly longer.
Cataract surgery is generally painless. Local anesthesia is used, so the patient does not feel any pain during the procedure. Mild discomfort may occur afterward but usually lasts for a short time.
Most patients can return to normal activities within a few days after surgery. However, heavy lifting and strenuous activities should be avoided for several weeks as per doctor's advice.
The eye begins to heal within a few days after surgery. Full recovery typically takes several weeks. During this time, prescribed eye drops should be used regularly and eye hygiene should be maintained.
Glasses may be needed for near or distance vision after surgery, depending on the type of artificial lens implanted. If trifocal lenses are used, glasses may not be necessary. Your doctor will recommend the best option for you.
Cataracts develop in the natural lens and do not recur once removed. However, the membrane behind the artificial lens can become cloudy (posterior capsule opacification). This can be corrected with a simple laser treatment.
Cataracts usually occur at an older age, making elderly years the most common period for surgery. However, cataract surgery can be performed at any age if vision loss affects quality of life.
Both eyes are operated on different days with at least one day gap in between.
No. Patients are discharged after surgery.
A detailed eye examination is done before surgery. On the surgery day, wear comfortable clothes and you may need to take or stop certain medications as advised by your doctor. Your doctor will provide detailed instructions.
