Following a retina tear and repairs which have been made how long does it take for red blood cells and grey cloud/dots to clear from vision?

Variable: Vitreous separation and vitreous hemorrhage occur with retinal tears-causing vitreous floaters, and floaters in your vision. This can also result in hazy vision. The laser procedure helps to prevent the tear from progressing to a retinal detachment; however it does not resolve the vitreous floaters. The vitreous floaters can takes weeks to months to improve.

Depends: How long it takes a hemorrhage to clear without intervention varies from one week to never. Never means that the hemorrhage simply will not clear without surgery. So it could be soon or ....

Much by 6weeks: Much of the clearing of blood occurs in 6 weeks, like a deep bruise. Residual floaters become less noticable over 6 months but will be still observed when say looking at white or blue backgrounds, such as snow or the sky. Against vivid colors or plaids they'll be unnoticeable.
