Well, to clarify, the doctor used laser beam to cut the lids instead of using knife. The advantages of using laser beam according to the doctor is that there is less bleeding and bruises, wound will heal faster. I have not gone for the knife so I cannot commend on the healing time. But in my case, it took 2 weeks for the swelling and bruises to be 80% gone, which is considered fast. The wound is 'stitched' back by using skin glue, instead of thread. So, there is no need to go back to remove the thread or stitches like the traditional one. It saves time.
Anyway, I originally posted 'nose job' topic, but not many people reply and now it drifts to eyelids.
