Blepharoplasty or surgery is the choice for excess skin. If the problem is wrinkles, that is treated with a laser.
There are many options for eyelid surgery incisions. The good news is, they all have nearly identical outcomes when used by an experienced surgeon. Lasers sound sexy, but are more of a marketing gimmick than a breakthrough for eyelid surgery. Laser resurfacing of the eyelid skin can be done, but is not as powerful or effective at rejuvenating sagging lids as a blepharoplasty.
