It says in the Acuvail instructions use one dose only , does that mean one drop and throw the rest?

ACUVAIL 0.45% is available as a sterile solution supplied in clear, LDPE, single-use vials, yes its meant for 'one dose use only'.

However please do double check it with a optometrist/doc/pharmacist who prescribed the med. Take care.

Yes, you are correct. Use it immediately after opening and throw away any solution that is not used.
This from http://www.drugs.com/pro/acuvail.html
"... Patients should be instructed that the solution from one individual single-use vial is to be used immediately after opening for administration to the affected eye. The remaining contents should be discarded immediately after administration. Avoid allowing the tip of the vial to contact the eye or surrounding structures because this could cause the tip to become contaminated by common bacteria known to cause ocular infections. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions."
