FIL needs cataracts surgery. He has been offered it at a fantastic eye hospital very quickly and on the NHS.
He has decided he wants to pay for a certain type of lens in his eyes to give him perfect vision. (He currently wears glasses).
They have told him if he wants to do this, he will have to have the ehe thing privately and will be over £3000 plus consultation fees etc.
Him and MIL have no money and he would have to get our a credit card for this.
AIBU for thinking he is selfish to consider paying when he can get it for free? Mil has asked him not to as the cost is so huge.
He said he doesn't have any issue wearing glasses but would like to experience 'perfect vision'.l without glasses. If there was no cost implication involved I would say go for it but there is a big one he can't afford. Due to other complications with his health that affect his eyes it may not be effective anyway and to pay for something like that baffles me. 
MIL is asking is to talk sense into FIL and I don't really know what to say apart from 'don't pay for it'.
AIBU?
