eye issues

I have been feeling better.. Currently I'm on mepron, ketek, diflucan, nystatin... i was on avelox for bartonella but couldn't handle it so until my next appt my llmd said ketek would hit the bartonella...Ive been feeling better lately.. but I've been having eye issues in my right eye.. It kinda gets blurry... I thought it was my contacts and I put new ones in and its still happening in my right eye.. I've also noticed occasional floaters but very infrequently... could this be from die off or an active infection?
