How long will my droopy eye last? I had Botox 6 weeks ago. Will my eye return to normal? (Photo)

I'm sorry that you had to experience this adverse effect from your botox treatment.   Botox generally lasts 3-4 months you will need to wait for the botox to wear off then your eye will go back to normal.   

You are doing the right thing taking iodipine drops. Repeated use can make the eye dry so I recommend buying some lubricating eye drops to use at night. No matter what most clinicians say eyelid ptosis is a side effect of Botox irrespective of technique. There are many other factors in play apart from technique. Aftercare post Botox treatment is paramount. Bruising can increase the risk as well as rubbing of the eyes post treatment. The important thing is that the side effect is temporary. The cases I have seen settle down after 6 weeks but dependent on the severity can last much longer.  

Generally I find that when Iopidine works at all, it indicates the upper eyelid ptosis will resolve in 4 to 6 weeks, possibly sooner.  When the Iodine does not initially work, the ptosis will last much longer.
