Thank you for your question. You are asking about reverting back to your double eyelids after severe allergies left you with swollen eyes and multiple eyelid creases. I can certainly help you based on your photos alone, and give you some guidance in the absence of a physical exam. I’m Dr. Amiya Prasad. I’m a Board Certified Cosmetic Surgeon and Fellowship-trained Oculoplastic Surgeon. I’ve been in practice in Manhattan and Long Island for over 20 years. I’m well known for my work with Asian double eyelid surgery for both primary and revisional surgery, ptosis surgery, as well as primary and revision lower eyelid surgery. It is important to assess the creases of your eyelids after your allergies have been managed, and swelling has dissipated. Since you didn’t provide a picture of how your eyelids looked before your allergies, it’s difficult to establish a baseline of your double eyelids. It’s also unclear if you had a not fully defined or weak eyelid crease prior to your allergic reaction, which may have been weakened by swelling. Multiple upper eyelid creases, or a partially formed but undefined double eyelid, are usually caused by a weak connection between the upper eyelid skin, and the levator muscle that lifts the eyelid. Swelling can obscure either a strong or weak connection. Once the swelling is resolved, your situation can be better assessed. I suggest you manage your allergies first, then if you are still unhappy with your eyelid crease, or are still experiencing multiple creases, see a cosmetic surgeon who performs a lot of Asian double eyelid surgery. A weak eyelid crease, or a multiple eyelid creases can be made more defined with Asian double eyelid surgery where the connection between the muscle and the skin is made stronger, probably with the non-incisional method for a young person like you, who doesn’t have extra skin or fat in the upper eyelids. I hope you found this information helpful. Thank you for your question.
