Frequently asked questions

What is a cataract?

A cataract is a clouding of the eye’s natural lens. It usually develops gradually with age and can make vision blurry, hazy, or less clear.

When should cataract surgery be considered?

Surgery is usually recommended when cataracts begin to interfere with daily activities such as reading, driving, working, or recognizing faces. The decision depends more on how much your vision affects your daily life than on how “mature” the cataract is.

What are the common symptoms of cataracts?

Common symptoms include blurred or cloudy vision, glare or halos around lights, difficulty seeing at night, faded colors, and frequent changes in eyeglass prescription.

How is cataract surgery performed?

During cataract surgery, the cloudy natural lens is removed and replaced with a clear artificial lens called an intraocular lens or IOL. The procedure is usually performed through a very small incision and typically does not require stitches.

How long does recovery take after cataract surgery?

Many patients notice clearer vision within a few days, although some blurring or mild irritation may occur initially. Most people can resume many normal activities within several days, while complete healing usually takes about 4–6 weeks.

Is cataract surgery painful?

Cataract surgery is usually not painful because numbing eye drops or local anesthesia are used. You may feel mild pressure, cool fluid, or slight discomfort during the procedure, but significant pain is uncommon.

What causes cataracts?

Most cataracts occur naturally with aging. Other factors such as diabetes, eye injuries, prolonged steroid use, previous eye surgery, and excessive ultraviolet exposure may increase the risk.

Can cataracts be treated with eyeglasses or medicines?

In the early stages, changing your eyeglass prescription or improving lighting may help. However, there are currently no proven eye drops or medicines that can permanently remove a cataract.

How long does cataract surgery take?

The operation itself commonly takes around 10–30 minutes.
