What is Cataract?
A cataract is a clouding of the natural lens inside the eye, which leads to decreased vision. The lens of the eye is normally clear and helps to focus light onto the retina, allowing us to see clearly. However, as we age, the proteins in the lens may start to clump together, causing clouding or opacification of the lens. This clouding prevents light from passing through the lens properly, resulting in blurred or hazy vision.
Cataracts are a common age-related condition and are one of the leading causes of vision loss and blindness worldwide. They typically develop gradually over time, and the progression of cataracts can vary from person to person. In the early stages, cataracts may not cause noticeable vision changes, but as they advance, they can significantly impact visual clarity.
Symptoms
Symptoms of cataracts may include:
-
Blurred or hazy vision: Objects may appear blurry or less sharp than before.
-
Increased sensitivity to light: Bright lights may cause discomfort or glare.
-
Poor night vision: Difficulty seeing in low-light conditions or at night.
-
Fading or yellowing of colors: Colors may seem less vibrant or appear yellowish.
-
Double vision: Seeing multiple images of a single object.
-
Need for frequent changes in prescription glasses or contact lenses.
Treatments
Treatment for Cataracts:
-
Surgical removal of the cloudy lens
-
Replacement with an artificial intraocular lens (IOL)
Here's an overview of cataract surgery
Cataract Surgery: Cataract surgery is typically performed on an outpatient basis and is generally painless due to the use of local anesthesia. During the surgery, the eye surgeon makes a small incision in the cornea and uses ultrasound or laser technology to break up and remove the cloudy lens (cataract). Once the cataract is removed, an IOL is implanted to replace the natural lens. IOLs come in various types, including monofocal, multifocal, and toric lenses, which can correct vision for distance, near, or astigmatism.
Common FAQ's for Cataract
1
Who is at risk of developing cataracts?
Cataracts are most commonly age-related and tend to occur in individuals over the age of 60. Other risk factors include a family history of cataracts, excessive sun exposure, smoking, diabetes, certain medications, and eye injuries.
2
Does cataract surgery hurt?
Cataract surgery is usually painless as it is performed under local anesthesia. Patients may experience mild discomfort or pressure during the procedure, but it is generally well-tolerated.
3
How long does it take to recover from cataract surgery?
The recovery time after cataract surgery is relatively short. Most people can resume normal activities within a few days after surgery. Vision may continue to improve in the weeks following the procedure as the eye heals.
