Blepharoplasty could be both functional and cosmetic surgery, by removing extra skin and tissue of eyelids to restore full vision or get a pair of bigger eyes. The incisions might be internal or external. The first two days, it might be very painful and uncomfortable. The eyelids would be so swelling that your vision might be impacted. Because the glands are located in eyelids, so eye dryness is a very common side effects after the surgery, which apparently impacts tear film production. You need apply some ointment on eyelids, which can moisturize the incision, and also lubricate eyes. As to compress, cold compress and warm compress have different functions. Besides of knowing its effects and mechanics, you also need to know the proper timing for different compress. Both the two methods can provide temporary relief from pain. But the cold compress strains muscle and skin, while warm compress increases blood flow and reduce stiffness. Because after this surgery, your eyelids are swelling and stiff, so I suggest you to apply warm compress which could minimize the stiffness and pain. In such situation, ice compress might cause your skin and muscles tighten, which is somewhat miserable now. Although warm compress could help, it is better not to use it for over 20 minutes.
