Eye surgery for Luna

Was told by vets from pets at home it was conjunctivitis a few weeks ago and despite doing eye drops and gel to help clear her eyes, they got better but then yesterday morning she suddenly couldn’t open her eyes; we changed vets and got an emergency appointment today and found out she has Entropion, meaning her eyelids are going inward so the hairs are hitting of her eye and causes her pain and we only found this out today since she got misdiagnosed by the last vets. It’s £450 for the surgery and it’s tomorrow at 8am, anything to help would be much appreciated! We can get money but unsure how we’re gonna pull a whole £450 in less than 24 hours  , thank you for helping it means the world to me
