In over 20,000 surgeries performed across my career, the most common thing I hear from cataract patients is: "I wish I hadn't waited so long." There is a widespread belief that cataract surgery should be delayed until the cataract is "ripe" or "mature." This is a medical myth that dates back decades, and it needs to be corrected.
Modern phacoemulsification and Femto Laser-assisted cataract surgery is far easier to perform on an early-to-moderate cataract than on a dense, mature one — and the outcomes are significantly better. The right time to operate is when the cataract is affecting your quality of life, not when it has destroyed it.
Here are the five signs I look for — and that you should not ignore.
The 5 Signs
Your vision is blurry even with your glasses or lenses corrected
A cataract clouds the lens inside your eye. Unlike a refractive error, it cannot be corrected by a new glasses prescription. If your ophthalmologist has told you your prescription is stable but your vision is still not crisp, the culprit is almost certainly the cataract. When updating your glasses no longer helps, it's time to consider surgery.
You see halos, glare, or starbursts around lights — especially at night
Glare and halos around headlights, streetlights, and oncoming traffic are classic cataract symptoms. Many patients first notice this while driving at night and simply stop driving after dark. If night driving has become unsafe or anxiety-inducing, that is a significant quality-of-life impairment that surgery can definitively resolve.
Colours look faded, yellow, or washed out
A lens affected by nuclear cataract — the most common type — gradually yellows and browns, filtering out blue wavelengths. You may not notice this change because it happens slowly, but patients who have undergone surgery on one eye often report seeing dramatically more vivid, crisp colour with the operated eye compared to the other. This colour shift is a clear sign of significant lens opacity.
You're experiencing "second sight" — suddenly needing fewer glasses for reading
This sounds like good news but it isn't. A certain type of cataract (nuclear sclerotic) changes the refractive power of the lens as it hardens, temporarily improving near vision. Patients are often delighted — until the cataract progresses further and vision deteriorates rapidly. "Second sight" is a warning sign, not a reason to postpone evaluation.
Your visual impairment is affecting daily activities, safety, or independence
This is the most important sign of all. If poor vision is causing you to avoid reading, restrict your driving, struggle to recognise faces, or fear falling — the impact on your quality of life and independence is the most compelling reason to proceed. Cataract surgery has one of the highest patient satisfaction rates of any elective surgical procedure in medicine.
This decades-old advice is no longer medically sound. A very dense, mature cataract is harder to remove surgically, carries higher complication risk, and often produces worse visual outcomes than an early-to-moderate cataract removed with modern techniques. Do not wait for a mature cataract.
What Modern Cataract Surgery Actually Involves
At The Eye Clinic, I perform both phacoemulsification (Phaco) and Femto Laser-Assisted cataract surgery. Both techniques remove the clouded natural lens through a very small incision — typically 2–2.8mm — and replace it with a clear artificial lens (IOL) that sits permanently in the eye.
The procedure typically takes 15–20 minutes under local anaesthesia (eye drops only — no injections, no general anaesthesia). Most patients return to normal activities within 24–48 hours. There is no patch, no bed rest, and no extended recovery.
Femto Laser-Assisted surgery uses a laser to make precise, computer-guided incisions and soften the cataract before removal — reducing the ultrasound energy needed inside the eye. This translates to faster healing, better wound sealing, and superior precision, particularly for patients choosing premium IOLs.
Choosing the Right Lens (IOL)
One of the most important conversations we have before surgery is about intraocular lens choice. The type of lens placed inside your eye determines your vision quality for the rest of your life. Options include:
- Monofocal IOL — excellent distance vision, glasses still needed for reading. The most commonly used and covered by health insurance.
- Toric IOL — corrects astigmatism simultaneously, reducing dependence on glasses at distance. Ideal if you have significant pre-existing astigmatism.
- Trifocal / Multifocal IOL — provides near, intermediate, and distance vision. Many patients achieve spectacle independence for most tasks. Premium cost not covered by insurance.
I personally counsel every patient on IOL selection based on their lifestyle, occupation, other eye conditions, and expectations. There is no single "best" lens — only the best lens for you.
"Every patient who has waited too long has said the same thing: they wish they'd come sooner. I've never had a patient say they operated too early."

If you recognise any of the five signs above, the first step is a comprehensive cataract evaluation at The Eye Clinic. This takes approximately 45 minutes and includes:
- Visual acuity and refraction measurement
- Slit-lamp examination of the lens
- Dilated fundus examination to assess the retina
- IOL power calculation (biometry)
- A detailed discussion of surgical options and timing
You will leave with a complete understanding of your cataract's stage, the surgical plan that suits you, and a clear answer to the question you came in with: Is it time?
