Could my Face Lift/eyelid Lift Have Contributed to my Loss of Vision?

Hello, and sorry to hear about the issue you are experiencing. In general, the side effects of a facelift may include the following:

1) Bruising
2) Swelling
3) Bleeding
4) Hematoma
5) Mild pain which can be controlled with pain medication

It is not likely blood would collect behind the eye following a facelift. It is possible this is due to something else. Did your eye doctor mention inflammation from your surgery as a possible cause? There is not a medication that will help your scar and simultaneously improve the condition of your eye. You are almost 2 years post-op, and at this point your scar has healed. It is possible to improve the appearance of the scar with laser treatment. But only an exam can tell for sure, and I would recommend speaking with your surgeon about treatment options. I hope this helps, and I wish you the best of luck.

I agree with Dr Troung that your  vision loss is not related  to your eyelid or facial surgery.  I am not sure why you have had this misfortune but be sure and see 3 ophthalmologists to get an array of opinions about your future care.   You should see your original plastic surgeon about scar healing. There are many great treatments for thick red scars including the Obagi system combined with Kelocote.  See your surgeon.  My Best.   Dr C.
