Dr Oyakawa,
Thanks for your reply.
I did some google in the last few days and found quite a lot of people have the Atropine after the sclera surgery but not many mentioned for how long.
I also found an article mentioned the reason of using Atropine
"...
Keeping the pupil big is important after surgery to prevent scar tissue formation (synechia). This is especially true for children with iritis. However, mydriatics are not always used after eye surgery as in some cases pupil dilation is not desired.

I have never routinely used atropine after retinal surgery. I know some retinal docs use it. It makes it easy to exam the eyes since it is already dilated and it is supposed to decrease ciliary spasm. Years ago, I use homatropine which has a much shorter effect and usually stopped it in a week.
I have not routinely used a post operative dilating drop after retina vitreous surgery for the past 10 years. In some cases I have put in atropine to have the eye dilated the next day for a quicker post operative visit. In the rare patient with discomfort, I have used homatropine for a few days to a week.
