A cataract is clouding of the eye's lens that develops over time, mostly with age. It reduces vision gradually.
Symptoms
- Blurred or hazy vision
- Sensitivity to light, glare and halos at night
- Colours looking faded
- Frequent changes in glasses prescription
Treatment
The only lasting treatment for a cataract is surgery: the clouded lens is removed and replaced by an artificial intraocular lens. The operation is usually short and often done with numbing drops.
Lens options
- Monofocal lenses: generally focus at a single distance.
- Multifocal / extended-depth lenses: aim to support vision at more than one distance.
- Toric lenses that correct astigmatism
The choice is made with your physician according to eye structure, lifestyle and expectations.
Recovery
Drops are used for a few weeks; avoid rubbing the eye and heavy lifting. Vision usually improves noticeably in a short time. Seek help straight away for pain, redness or a sudden drop in vision.
