Does a cataract have to "ripen" before surgery?

“Wait until the cataract is ripe.” Many patients have heard this. The right question is: wait for what?

What do the sources say?

In the reliable sources we read, a cataract being “ripe” is not a condition for surgery. If a doctor has a specific reason to wait, ask them what it is.

What decides the timing of surgery today?

According to the sources, surgery is usually suggested when a cataract gets in the way of daily activities, such as reading, driving or watching television. Things the doctor takes into account:

• How much your vision interferes with daily life
• Whether one eye or both are affected
• Other eye or general health conditions
• Your own opinion and preference

The NEI source says that waiting usually does not harm the eye and does not make a later operation harder. But that does not mean “everyone should wait”. In some patients, for example with a narrow angle in the eye, the doctor has another reason for surgery. Make the decision together with your eye doctor.

What helps in the meantime?

For the early stages, the sources name:

• Better light for reading
• Anti-glare sunglasses
• A magnifier
• Glasses or lenses with a new prescription

These do not remove the cataract. They only help until surgery becomes necessary. Surgery is the only way to remove a cataract.

Questions to ask the doctor

• How much of my vision problem is due to the cataract and how much to something else?
• With my situation, is it better to operate now or to wait?
• If I wait, how often should I be examined?
• What sign means I should come back sooner?
• What should I expect from my vision after the operation?

A reminder

Cataract surgery does not restore vision that has been lost because of another condition, such as macular degeneration, glaucoma or diabetic eye damage. That is why a full examination before deciding is important.

If your vision suddenly falls, this is not a cataract. See the guide “When should I get urgent help?”.
