Cloudy eyes

[Doggotired]

Hi,
My lad was castrated today, he’s 5 and half months old and everything well. He’s been home a few hours and apart from being a bit wobbly he’s been completely fine. However I’ve just noticed both his eyes look cloudy.... I thought it was the light but it’s not. Is this a side effect of being put under does anyone know?
He has his check up on Saturday so will speak to the vet then but just wondering if anyone has come across this before?
Thanks

Might be the ketamine. Their probably still at work if you ring up.

The vet nurses have to check them thoroughly before they leave anyway so he must have passed the checks.

I’ve just missed them... they close at 6.30. He seems completely normal in himself, he’s playing with his toys like nothing has happened! Will see how he’s looking in the morning and ring them if it’s stil the same. Thanks
