Cataract Surgery

What is a Cataract?

A cataract occurs when the natural lens of the eye becomes cloudy, leading to:

Blurred or dim vision

Sensitivity to light

Difficulty seeing at night

Faded or yellowed colors

Cataracts are most commonly related to aging, but they can also develop due to trauma, medical conditions, or long-term medication use.

How is Cataract Surgery Performed?

Cataract surgery is typically performed using a modern technique called phacoemulsification:

A small incision is made in the eye

Ultrasound waves are used to break up the cloudy lens

The fragmented lens is gently removed

A clear artificial lens (intraocular lens – IOL) is inserted

The procedure usually takes 10–20 minutes and is performed under local anesthesia.

Types of Intraocular Lenses (IOLs)

After removing the cataract, an artificial lens is implanted. There are several types:

Monofocal Lens: Provides clear vision at one distance (usually far)

Multifocal Lens: Improves both near and distance vision

Trifocal Lens: Offers clear vision at near, intermediate, and far distances, reducing dependence on glasses

Recovery Process

Most patients go home the same day

Vision usually improves within a few days

Full recovery typically takes 1–2 weeks

Eye drops are prescribed to prevent infection and support healing

Benefits of Cataract Surgery

Improved quality of life

Reduced dependence on glasses (especially with advanced lenses)

Is Cataract Surgery Safe?
