When can one go to a hot yoga class (100 ~ 109 degrees) post an incision double eyelid surgery?

This is something that should be answered only by your own surgeon. In my own practice I would have no problems with you returning after a couple of weeks.

I recommend a full 3 weeks for this type of physical activity.  Immediately after surgery, the tiny capillaries are very delicate and can break open if you are too active too soon.  Eyelid surgery is a huge investment in time, energy and expense.  Returning to vigorous physical activity too soon can adversely affect the delicate healing process.  Carefully follow your surgeon's instructions.

Dear weyeh327Thank you for your question!  Please check with your surgeon about returning to your activities!With Warm RegardsTrevor M Born MD

As long as there are no complications like infection or opening of the wounds, I recommend for all of my patients to return to full activity in 7-10 days after surgery.  Make sure that your surgeon is aware of your concerns prior to returning to yoga.  Namaste!

Thank you for your question. Each surgeon has their own post op instructions. I usually tell my patients they can return to light activity after 2 - 3 weeks. Good luck with your recovery.

There are actually 2 concerns as part of your question: the hot part, meaning sweat might be dripping into your eyes and along the incisions. As long as you are more than 7 days out and sutures have been removed, that is all fine. The second concern is actually yoga, where you may spend a lot of time in down dog position. Because double eyelid incision surgery can have prolonged swelling (due to necessary disruption of pretarsal lymphatics), you need to be careful and listen to your body. You can certainly try it after 7-10 days after surgery. But if after a yoga class, you are more swollen or you feel like your head is going to explode, I would wait a couple more weeks, even a month. 

After eyelid surgery the patient may begin reading after about two to three days and can
expect to return to work at approximately five to ten days. Use of
contact lens may be resumed after two weeks . The patient should not consume alcohol after the surgery.
More strenuous activities and alcohol consumption may be resumed after
three weeks. Bruising and swelling should be gone after several weeks.
