What Are Cataracts?
A cataract is the clouding of the eyeβs natural lens. The lens normally works like a camera lens, focusing light onto the retina for clear vision. Over time, proteins in the lens can break down and clump together, causing cloudy or blurry vision.
There are different types of cataracts:
- Nuclear cataracts β form in the center of the lens, common with aging.
- Cortical cataracts β wedge-shaped opacities around the edges.
- Posterior subcapsular cataracts β form at the back of the lens, progress faster.
- Congenital cataracts β present at birth due to genetics or infections.

Diagnosis of Cataracts
Cataracts are diagnosed during a comprehensive eye exam, which may include:
- Visual acuity test
- Slit-lamp examination
- Retinal exam
- Tonometry (to rule out glaucoma)
Early detection is crucial because it allows for better management before significant vision loss occurs.
Treatment Options for Cataracts
Cataracts cannot be treated with medication, diet, or eye drops. The only effective treatment is cataract surgery, which involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL).
Types of cataract surgery:
- Phacoemulsification (Phaco): The most common and minimally invasive method.
- Extracapsular cataract extraction (ECCE): Used for advanced cataracts.
- Laser-assisted cataract surgery: A newer, precise technique.
Recovery is usually quick, and most patients regain clear vision within a few days to weeks.
