About what percent of people who get cataract surgery get clouding of their eye afterwards and need YAG laser surgery to clear it up?

The figure I use for patients having surgery now is 10-20% in their lifetime. Yag laser if needed is quick, simple, painless and low risk.

The rate of PCO has been dropping over time due to improved lens designs, and I hadn't seen a good current overall figure, different sites give different estimates. Some sites suggest it is  about 20%:

This NHS site says less than 10%:

The rate depends largely on the lens model, so for some lenses you may be able to find studies indicating the likely PCO risk.
