How are cataracts removed?

Cataracts are one of the most common causes of vision loss as we age. Fortunately, the solution is straightforward—and highly successful.

But how exactly are cataracts removed?

In this blog, we’ll explain the steps of cataract surgery, what to expect, and how this short procedure can restore clear vision, often in under 30 minutes.

What is a cataract?

A cataract is when the natural lens inside your eye becomes cloudy. This happens gradually as proteins in the lens clump together with age.

Symptoms of cataracts include:

• Blurred or misty vision
• Glare and halos around lights
• Difficulty reading or driving, especially at night
• Faded colours
• Frequent changes in your glasses prescription

The only way to treat cataracts is with surgery. Glasses may help early on—but once the cataract progresses, the cloudiness can only be fixed by replacing the lens.

How are cataracts removed?

Cataract surgery is a safe, modern procedure done thousands of times every day. Here’s what happens, step by step:

Step 1: Preparation and anaesthetic

You’ll be awake for the procedure, but don’t worry—it’s painless.
Before surgery:

• You’ll be given local anaesthetic eye drops to numb the eye
• You might receive a mild sedative to help you relax
• The skin around your eye will be cleaned, and a sterile drape will be placed over your face (with breathing room, of course).

Step 2: Keeping the eye open

A small, comfortable clip is used to gently hold your eyelids open. You won’t feel the urge to blink, thanks to the anaesthetic drops.

Step 3: Removing the cloudy lens

The surgeon makes a tiny incision in the edge of the cornea (the clear surface of the eye). Using a technique called phacoemulsification, the surgeon:

• Breaks up the cloudy natural lens using ultrasound energy
• Removes the broken-up lens pieces through the small incision.

This part takes just a few minutes.

Step 4: Inserting the new lens

Once the cataract is removed, the surgeon inserts a clear intraocular lens (IOL) in its place.

This lens is carefully folded, inserted through the tiny incision, and then unfolds into position.

The lens is permanent and designed to last a lifetime. It doesn't require care or replacement.

Step 5: Finishing the procedure

No stitches are usually needed—your eye naturally seals itself. You’ll then rest in recovery for a short time before going home the same day.

How long does cataract surgery take?

The entire procedure usually takes 10 to 15 minutes per eye. You’ll be at the clinic for a couple of hours to allow time for preparation and recovery.

Will I feel anything?

Most people feel nothing during surgery—just bright lights and some gentle pressure or movement.

Thanks to modern anaesthesia, the experience is painless and surprisingly quick.

What happens after the surgery?

You’ll go home with an eye shield and some drops to use for a few weeks. Vision may be blurry for the first day or two, but most people notice improvement very quickly.

Follow-up appointments ensure your healing is on track.

Can I choose what kind of lens I get?

Yes—especially with private surgery.
Options include:

• Monofocal lenses (set for one distance—often far)
• Multifocal or trifocal lenses (help you see near and far)
• Toric lenses (correct astigmatism).

At Mitry Vision, we help you choose a lens that fits your eyes and lifestyle.
