I a red spot on the white of the eye cause for alarm after cataract surgery?

Hello. Thank you for posting.

We cannot say what this is, no one can over the internet, but a common cause is a small broken blood vessel-called a subconjunctival hemorrhage-that occurs in the very fine blood vessels in the clear thin layer of tissue called the conjunctiva. This can happen from manipulating the conjunctiva during surgery or even from sneezing or coughing.  If it is a subconjunctival hemorrhage it may appear to get worse and spread around the surface of the eye before it gets better.  There should be no pain, no discharge, no light sensitivity or any signs or symptoms of inflammation and your vision should remain stable.  If any of these become a noticeable problem or the vision changes contact your cataract surgeon right away. You might want to contact him or her anyway for your peace of mind. 

best,

Helena
