It's not like she's asking for breast implants or liposuction(or something else that is not reconstructive in nature). It's lasik, and it'll help her quality of life, no more worrying about breaking her glasses or losing contacts.

We dont know if she works in special ed where getting hit in the face could be a normal occurance for her. Maybe she struggles with contacts. Either way there are a lot of reasons for someone to want to go that route.

Also, comparing lasik to something like nonreconstructive cosmetic surgery is disingenuous. One is completely for aesthetics, the other affects function.
