Cataracts

A cataract is a clouding of the lens inside your eye. It's an extremely common part of getting older, it comes on slowly, and it's very treatable — cataract surgery is one of the most successful procedures in medicine.

What it is

Inside your eye is a clear lens that focuses light onto the retina. Over the years this lens can gradually turn cloudy — that cloudiness is a cataract. It's a bit like looking through a foggy or frosted window.

Cataracts usually develop slowly over months or years, and most are simply age-related. When they start to get in the way of everyday life, the cloudy lens can be removed and replaced with a clear artificial one.

Signs of cataracts

  • Cloudy, blurry or dim vision
  • Colours looking faded or yellowed
  • Glare or halos around lights, especially at night
  • Needing more light to read
  • Frequent changes to your glasses prescription
  • Difficulty driving, particularly after dark

Recognise these? Book a consultation and we'll help you get to the bottom of it.

What causes it

Age is by far the most common cause — most cataracts are simply part of getting older.

Some things can bring them on earlier: diabetes, long-term steroid medication, an eye injury, or years of UV exposure.

How we help

There's no drop or exercise that clears a cataract — the only way to treat it is to remove the cloudy lens and replace it with a clear one. Modern cataract surgery is quick, gentle and highly effective.

Dr Leong will confirm whether a cataract is behind your symptoms and talk you through your options, including the lens choices that can reduce your reliance on glasses afterwards.

Common questions

Do cataracts have to be removed?
Not straight away. Early on, a change of glasses may be enough. Surgery is considered once the cataract starts affecting things you want to do — reading, driving, hobbies. It's your decision, guided by how much it's bothering you.
Can cataracts come back?
The cataract itself can't return, because the natural lens is replaced. Some people notice a bit of haze months or years later as the lens capsule thickens — this is easily cleared with a quick, painless laser treatment.
Is cataract surgery painful?
No. It's done under local anaesthetic with numbing drops, so the eye stays comfortable throughout, and most people are back home the same day. Many are surprised how quick and gentle it is.
How long does it take to recover?
Most people notice clearer vision within a day or two, with the eye settling fully over a few weeks. Dr Leong will give you simple drops and aftercare, and check that it's healing well.
