What is a bad idea is to function with both eyes being different. So, 
either use a contact lens in the left eye to make it agree with the 
right eye, or have the implant match the left eye. I think the first 
alternative is the one I would choose, but this was because I a) 
never  used contacts and b) refuse to look into a camera viewfinder 
with glasses. Until my both eyes had cataract surgery, I used to put 
a 2 diopter lens in my camera viewfinders.

Hope what I wrote helps and is not too confusing.
