Hi, I'd like to get in to lasik and I need a part-time internship... any suggestions?

Are you currently in school? Many clinics/doctor's offices will not give an internship/externship unless you are in optometry or ophthalmology school and in good standing.

J9 is corrrect, you need to contact your college advisor and also your dept head, they may have some suggestions for you.

Or get certified as an Ophthalmic assistant first. And do that.
