You have not mentioned the procedure done on the retina in your question. If it was vitrectomy for a vitreous haemorrhage it means the disease had already progressed to a very advanced stage. A bleed post surgery would suggest the disease process is still active. At this point it is difficult to say how things will progress. Laser is required at a future point when the bleeding settles down.

Hello This may take another few days to weeks for some improvement. Follow instructions of your retina specialist

Its a serious problem and may take time to recover,may need few more injections and inspite of that 100%recovery might not take place. So let us hope for the best.
