am sorry to learn about your experience. Let me answer your questions individually,
1. If an eye surgeon has examined your retina
after dilatation of the pupils and pronounced it OK, you have to learn to ignore the floaters
.. they are harmless and will go away one day, maybe after months or years. They are part of the process called aging.
2.Your power may be increasing due to one of 2 reasons.. a) ectasia or thinning of the cornea
due to excessive removal of tissue during the lasik. This can be confirmed by doing a corneal topography examination.
b) due to early development of cataract
.This can be confirmed by slit lamp biomicroscopy which is part of a routine eye examination.
3. For uveitis
, you need extensive blood tests to determine cause. If no cause is foundinspite of tests, it is labelled as autoimmune, i.e. an acting up of your own immune system which is supposed to protect you. If the attacks are frequent and severe, you may need systemic medication called 'immunosuppressive medication".
