Vitrectomy on high myopia eye

Hello,

I had bleeding in vitreous 3 months ago in my last week of pregnancy. Now my retina doctor is suggesting to do a vitrectomy because I bleeded pretty a lot and blood is not absorbing how he expects. He says that coagulated blood is becoming toxic to retina. Since I have high myopia (-7.5) I’m afraid of retina detachmnet. I wanted to ask if someone has vitrectomy on high myopia eye and there were any complications?

Thanks for your reply
