Yes, of course. A simple Pubmed query will bring a lot of occurrences : https://pubmed.ncbi.nlm.nih.gov/?term=Keratoconus+eye+rubbin...

For a complete argumentation and discussion about the case for the role of eye rubbing in keratoconus genesis, please look at this website : https://defeatkeratoconus.com/

(Disclaimer: I work closely with one of the main proponent of the eye rubbing hypothesis. However, please believe that I don't have any conflict of interest in this topic. I don't have anything to gain in raising awareness about this problem, except feeling that I'm doing something right)

Much appreciated! I certainly question it from personal experience, but I'm very interested to know more.
