Last winter, I buried + front cantula. I had to use the forehead muscles to open the black pupils of the eyes, so I was thinking about ptosis correction. It's been 8 months since the surgery, but now I can open my eyes wide just by using the strength of my eyelids. It's been a long time since I didn't use forehead muscles. If there is no severe blepharoptosis, it can be corrected with only burial.
