If the surgery is done with laser, it may be the reason they like you to be off the Accutane.
I would not think that it would be a ;problem. But again it is for your safety. they want to make sure that you heal well and have no complication.
Accutane and eyelid surgery
Conservatively, waiting 6 months after stopping Accutane to have eyelid surgery is reasonable and safe. The reason to stop Accutane is due to possible delayed healing with cosmetic procedures. This delay is traditionally associated with skin resurfacing procedures, such as chemical peel or laser treatment.
From a mediolegal standpoint, in the event of a complication, your surgeon will be blamed if surgery is not delayed 6 months.
The evidence that isotrentinoin affects the healing of eyelid surgery does not exit. The data that it affects the healing of skin resurfacing is poor at best. However, it is generally advised in the literature to wait at least 6 months before performing aesthetic surgery after taking isotrentinoin. Your surgeon is correct in following this conservative approach.
Acutane and eyelid surgery
it is only necessary to stop Accutane for 6 months to a year if you are going to have a skin resurfacing procedure such as laser or chemical peel or a dermabrasion. Having eyelid surgery 6 months after stopping the Accutane poses no additional risk.
