Although minor hand movements are not as vital in optometry and they are in dentistry, you still use them quite often; forign body removal, punctal irrigation, epilation, cyst expression...
These are things you could refer out, but they are pretty easy to do. I don't have any real advise, I just wanted to make sure you know it is not all, "1 or 2." Good luck, I hope you make a decision right for you.
