Followup: I've been advised to have a retinal scan, and some prelasik type scans (waveform, photoscan) to diagnose my problem. I don't know if the dye was used already. No one said they were doing it. With the other drops they said things like "this drop will dialate your eye". How often are corneal abrasions associated with double vision undetectable with the slit lamp alone? Should I go back and try to get the dye.
