In 2010, I was on this site (realself) and I suddenly recognised that the condition I had, had a name, "upper hollowness of the eye". I also discovered that this there were possible treatment optons, fillers, fat injections or pearl fat grafting (from Dr Meronk's excellent website).
I did not want to go down the temporary filler route so chose fat grafting.
In June 2011 I contacted Dr Sorensen (in London) and had my consultation. I didn't want scarring so we decided that we would go down the fat injection route.
Unfortunately the improvement was minimal. The hollowness was due to lack of fat in the actual socket so I didn't get the result I wanted. The brow was fuller put the hollowness was still there.
I returned to Dr Sorensen for actual pearl fat grafting in 05 Dec 2011. The discomfort was minimal post procedure. I made sure I slept in a sitting up position for 2 weeks to keep the swelling down. There wasn't significant swelling.The immediate result was quite lumpy especially when I looked down or closed my eyes. I had a bit of a panic attack because I was afraid that the lumpiness would stay. I visited Dr Sorenson a week after the procedure to have the stitches taken out. I used this opportunity to tell him of my concerns regarding the lumpiness. He said that we should give it a little while and that if it didn't resolve he would remove the lumpiness without any cost to me. So, I had the procedure on 5 December and on New Year's Eve I went out to celebrate the new year. The recovery period was very fast.
The lumpiness began slowly resolving itself and after about 3 months I would say that it probably had gone more or less completely. Some days the hollowness looked like it had returned but I think it was dependant on my hydration levels.
So now I am 2 years post op, I wouldn't say the result is not perfect but I would say that I am very very happy with the result. The pearl fat grafting has improved the look of my eyes by about 250%.
Dr Sorensen is very conservative in his procedures but I do wish that he had put a little bit more fat in than he did. I am considering going back to him and asking him to put a little bit more in.
I hope this information helps others who are facing a similar problem.
