Clouded, dimming vision is the hallmark of a cataract, and the fix is one of the safest, most common operations in medicine. Here's how the day unfolds.
What a cataract is
The lens inside your eye is normally crystal clear. With age its proteins clump together, clouding the lens so light scatters instead of focusing. Colours fade, glare worsens, and night driving becomes hard.
Cataracts develop slowly, so many people adapt without realising how much vision they have lost until it is restored.
The procedure
Surgery usually takes 15–30 minutes under local anaesthetic, and you stay awake but feel no pain. The surgeon makes a tiny incision, breaks up the cloudy lens with ultrasound, removes it, and slides in a clear artificial lens.
No stitches are needed in most modern cases, and you go home the same day.
Recovery
Vision often begins to clear within a day or two, with full settling over a few weeks. You'll use medicated eye drops and a protective shield at night for a short period.
Avoid rubbing the eye, heavy lifting, and dusty or chlorinated water until your surgeon clears you.
When to consider it
There is no need to 'wait until it's ripe'. When cataracts start interfering with reading, work, or driving, it is reasonable to discuss surgery. The outcome is excellent for the vast majority of patients.
