Cataracts: when to operate and key warning signs

When Should You Have Cataract Surgery?

Clear Signs It May Be Time for Cataract Surgery

One of the most common questions in consultation is simple:

“Doctor, when should I have cataract surgery?”

The answer does not depend only on age or on a number from the eye chart. It depends on how cataracts are affecting your quality of life.

What Is a Cataract?

A cataract is the progressive loss of transparency of the natural lens. In most cases it develops slowly, although some types may progress faster:

• Nuclear cataract (slow, progressive)
• Posterior subcapsular cataract (more symptomatic, faster)
• Diabetic cataract
• Traumatic cataract

Each type behaves differently. And each patient does too.

Should Surgery Be Based Only on Visual Acuity?

Not necessarily.

One of the most common mistakes is deciding surgery based solely on visual acuity (20/25, 20/40, etc.). In my clinical practice, I never make the surgical decision based only on that number.

The real question is not: “How well do you see?”
The real question is: “How is your vision affecting your daily life?”

Clear Signs It May Be Time for Surgery

Glare while driving at night

• Halos around lights.
• Difficulty with LED headlights.
• Feeling unsafe while driving.

Reduced contrast sensitivity

• Faded colors.
• Difficulty distinguishing fine details.

Frequent prescription changes

• Progressive myopic shift in nuclear cataracts.

Real functional limitation

• Avoiding driving.
• Reading less.
• Reducing activities.

When Surgery May Not Be Necessary Yet

Some patients with nuclear cataracts do not drive, read comfortably (sometimes without glasses), do not feel limited, and maintain a good quality of life. If daily life is not affected, surgery does not need to be rushed.

Cataract surgery is one of the safest and most effective procedures in modern medicine. But it should not be performed prematurely.

My Personal Surgical Approach

I never operate by protocol. I never operate because of external pressure. And I never operate based on a number alone.

I evaluate:

• Professional and lifestyle needs
• Functional risk (driving, falls)
• Visual demands
• Patient expectations
• The most suitable intraocular lens option

Cataract surgery is a strategic decision — not an automatic one.
