What is the prognosis for astigmatism?

About 30% of all people have astigmatism. In the vast majority of those, the condition does not change much after the age of 25. The presence of astigmatism as a child or young adult does not signify that an eye disease will later occur. Progressive astigmatism can occur with corneal trauma, repeated infections of the cornea, and degenerative diseases such as keratoconus.

Can astigmatism be prevented?

The common types of astigmatism cannot be prevented. The incidence of astigmatism due to trauma to the cornea can be decreased by attention to eye safety.
