How long does cataract surgery last?

Cataract surgery is one of the most commonly performed and successful procedures in modern medicine. But if you’ve been told you need the surgery—or you’re thinking about it—you might be wondering: How long does cataract surgery actually last?

The answer can refer to a few things: the duration of the procedure itself, the recovery time, and how long the results of the surgery last. Let’s take a closer look at each.

How long does the procedure take?

Cataract surgery is quick. In most cases, the surgery takes under 10 minutes per eye.

That said, your total time at the clinic will be longer, typically 2 to 3 hours. This includes:

• Pre-operative checks and preparation
• Pupil dilation
• The actual procedure
• Post-operative monitoring before you’re discharged

If you’re having both eyes done, they’re usually operated on a few weeks apart—to ensure the first eye heals well.

How long is recovery after cataract surgery?

The good news is that most people notice clearer vision within 24 to 48 hours.

Here’s a general timeline:

• First 24 hours: Mild blurriness or light sensitivity is normal
• 1 week: Vision usually stabilises significantly
• 4 to 6 weeks: Full healing, with final visual results

During this time, you’ll use eye drops to prevent infection and inflammation. You’ll also have follow-up visits with Professor Ursell to check healing.

How long do the results of cataract surgery last?

One of the best things about cataract surgery is that the results are long-lasting.

The cloudy natural lens is removed and replaced with a clear artificial intraocular lens (IOL). This lens is designed to last a lifetime and does not wear out.

However, there is one common condition to be aware of: posterior capsule opacification (PCO). Sometimes called a “secondary cataract,” this occurs months or years after surgery when the membrane behind the lens becomes cloudy.

PCO is easily treated with a quick, painless laser procedure (YAG laser capsulotomy) that restores clear vision in minutes.

What affects how long results last?

While the artificial lens itself is permanent, your overall eye health can affect long-term vision. Conditions such as:

• Macular degeneration
• Glaucoma
• Diabetes-related eye disease

...may affect your sight over time. That’s why ongoing eye check-ups remain important after surgery.
