When Can I Have Blepharoplasty After Being off Accutane?

If skin rejuvenation is part of the treatment plan, better to wait a year. Accutane can inhibit wound healing, due to its direct effects on dermal appendages that help to heal skin after injury or surgery.
 

The consensus regarding this issue is that Accutane impairs healing and that one should wait at least 6 months. However, there are no good studies or evidence backing this waiting period regarding eyelid surgery or rhinoplasty and Accutane. The thickness of the skin and the location of the incisions may also be important factors in the length of this waiting period. However, It is always better to error on the side of caution.

Accutane is know to produce a dry eye. You are still early in your treatment with the Accutane, and it is possible that your treating dermatologist will recommend extending your treatment course.
Generally, the dry eye symptoms improve a couple of months after the Accutane treatment. However, there are reported cases of severe dry eye following Accutane treatment that lasted for two years. For this reason, blepharoplasty should be postponed following your course of Accutane until your general ophthalmologist is satisfied that your eyes are making sufficient tears, and that surgery does not represent an undue risk.
For a similar reason, refractive surgery should be approached with caution following a course of Accutane.

Accutane should typically not interfere with the surgeries you are contemplating after a period of 6 months to one year.
The main reason Accutane is dangerous is for laser resurfacing; the laser is very prone to burning the skin of patients who have recently undergone Accutane. The pilosebaceous units have been dried up from laser and the heat from the laser tends to be absorbed by other adjacent tissues, causing burns.
Accutane may also inhibit reepithelialization. Better to wait six months before your proposed surgeries to be safe.

Accutane inhibits epithelialization by suppressing adnexal structures. Thus, invasive surgeries are contraindicated during Accutane therapy. I regularly manage patients requesting surgery while on Accutane.
I advise patients to wait 6 months after cessation of any amount of Accutane before undergoing any surgery. Thus, the ability to heal will be re-established.
This holds true, especially for blepharoplasty and rhinoplasty, two very important parts of the face.
