The good news, as other physician have mentioned is that the affects are not permanent and will wear off in 3-4 months, probably sooner.
Botox needs to be injected under the eyes very judiciously and in a very small amounts. A "snap test", should be performed first. Basically, to make sure your under eye skin snaps back and does not sag. It looks to me that you would "pass" that test. The problem was probably too much Botox was placed beneath the right eye, causing a narrowing. In addition it appears that your injector went too low and lateral below the right eye and may have had hit the zygomaticus minor muscle, thus leading to your asymmetric smile.
My suggestion would be to consult with an experienced dermatologist or plastic surgeon to correct the problems I outlined. You brow might need adjustment too.
As an aside, my colleague Dr. Arslanian implies that some Medi-Spas might be charging $7 a unit for Botox. If you find anybody charging that little, please request that you be given the opportunity to look for the hologram on the vial. Allergan has steadily raised the price of Botox once again, and the source of this Botox might be counterfeit.
