In some cases color changes need to be treated with bleaching creams. The upper eyelid stitches will be removed anywhere from three to ten days after surgery. If the incision was made with a scalpel, less healing time is needed. The incision line is generally formed in the crease of the lid, so when your eyes are open, it is usually invisible. On the lower lids, if the incisions were made inside the lid, there should be no visible trace at all.
Complications are very rare.
Blindness occurs in one of about 40,000 cases when a scalpel is used, and this happens because of bleeding behind the eye, but it is exceedingly unlikely with the laser. The laser simply creates less bleeding. Of course, because steel eye shields are used, there is virtually no chance of the laser hitting the eye itself and causing problems. Other possible complications include eyelid asymmetry, small cysts occurring along the top eyelid suture line, dry eyes, and uneven patches of fat remaining in the treated areas. But all of these complications are quite rare, and when they do occur, they are often corrected with minor surgery that in most instances doesn't require sedation or relaxation medicines.
