Cataracts: When Surgery Becomes Necessary and How You Recover

A cataract is a clouding of the eye's natural lens that develops slowly over time, until it begins to affect the clarity of your vision and your daily life. The question on many people's minds is this: when does surgery actually become necessary?

When do you need surgery?

The timing is no longer decided by how "ripe" the cataract is, as people once believed, but by how much it affects your life. It may be time for surgery if you notice:

• Difficulty reading or driving, especially at night.
• Blurred vision or faded colors that do not improve with a change of glasses.
• Bothersome glare around sources of light.

How is the surgery done?

Cataract surgery takes only a few minutes under anesthetic drops. The clouded lens is removed and replaced with a clear, permanent lens chosen to suit each patient's needs. It is one of the safest and most successful procedures in eye care.

What is recovery like?

Most patients return to their normal life about a day after surgery, with vision growing clearer over the first few days. The doctor advises against rubbing the eye or letting water reach it directly for a short period, and recommends using the prescribed drops until healing is complete. Most important of all, do not put the surgery off for too long, because neglecting a cataract can lead to complications such as raised eye pressure.
