Dear boriquaabe,
I would speak with your retinal specialist about the symptoms your having. There are many reasons for double vision following retinal detachment.

The double vision could be caused by a number of things. If you've had a scleral buckle it could be from that. Or it could be that you're having trouble fusing the different images from each eye. Or if you're aphakic this may also in some cases result in slight double vision at things up close. Or it may be an effect of the oil. There are other causes of double vision, but the ones above are the most common after RD surgery.
You need to talk w/your surgeon and discuss what exactly is going on. Only he/she will be able to tell you whether or not the double vision will be able to be fixed.
