Laser surgery includes many kinds, the common ones are myopic laser surgery, before the operation will apply surface anesthetic drugs or local anesthesia, this kind of surgery is generally painless, and the operation time is shorter, less traumatic, and there is no pain after the operation. In addition, laser surgery treatment, which also includes cosmetic class projects with mole and spot removal, pain is also generally tolerable. Laser cosmetic surgery includes both ablative and non-ablative lasers. The difference is that the wound will crust after the ablative laser treatment, while the non-ablative laser will not. Usually anesthetic will be applied on the surface of the pigmentation or pigmented mole before the surgery, and the anesthetic will penetrate deep into the skin after half an hour to one hour of local application. After the laser treatment, there is usually no significant pain. If some people are sensitive to pain, a nerve blocker can also be added to the appropriate area, which can also make the pain much less. After laser treatment, in order to reduce post-surgical pain, appropriate oral pain medication can be taken. Local cold compresses can also be applied to alleviate pain, and also to promote the local swelling to subside as soon as possible and reduce the occurrence of bleeding. If there is scab growth on the surface after laser treatment, do not pick it with your hands to avoid pain and infection. Therefore, through good care before, during and after surgery, laser treatment generally does not produce significant pain and there is no need to worry too much.
