Primary fat tissue was obtained and purified by liposuction. Nanofat and pearl fat were prepared and injected into lacrimal groove area in different layers and multiple points evenly to ameliorate depression. Visual analogue scoring (VAS) was used for evaluating injection pain. Dark eye circles, faint lines on lower eyelid, color spots and lacrimal groove depression between pre-operation pictures and post-operation pictures of 1 year follow-up were evaluated by patients＇ satisfaction scores.Results:All 78 patients revealed mild swelling and disappeared in 3 to 4 days.
