An eye Dr may not be too up on the internal aspects of your body. I'm sure he could wing it though...as many do, yet why take any chances. The Dr is going to simply use common sense.
And common sense dictates that I vote to postpone your cleanse. Geez,if there
is any question or doubt what's a couple of weeks?
An empty stomach and the body a week into the Master-Cleanse
be a good basis on which to take drugs of any kind.
In the interim, it's a great period to do a precleanse or liver flush,
while eating only 'good' foods and getting plenty of rest so you are
nice and strong for your surgery. Even though they say it is a 'simple'
procedure, it is still a radical stress/shock on your body like any surgery.
Enjoy waking up in the morning to a bright,'clear' day!!
