I started typing out a full background to whats happening but tbh it'd be like me posting War & Peace and you'd probably all have eye problems not to mention boredom issues long before reaching the end. So here's the Cliff Notes version which is still long

Note: I have always worn glasses for short sightedness and astigmatism - my shortsightedness is rather bad and I have a high prescription for both eyes.
1: 2 years ago diagnosed with PVD (posterior vitreous detachment) in left eye the PVD apparently caused a retinal tear, along with the PVD a cataract was discovered - no problems were detected with my right eye. Retinal tear means increased risk of retinal detachment so any issues with my eyes will carry increased risk.
2: Over the past 2 years cataract has increased and gotten more pronounce and now reduces the vision in my left eye and interferes with my daily life - not to mention bugs the shit out of me.
3: Just before Xmas I returned to see my original consultant surgeon to discuss treatment, BOTH eyes were checked & only the left eye was deemed to have any problems. Cataract needs to be removed via surgery - options and risks discussed (high risk surgery due to the tearing) natural lens will be replaced with a permanent contact lens (Inter Ocular Lens) risk of detachment post surgery rated at 50/50 however thats the same risk whether I have surgery or not. Told new lens will fully correct the vision in my left eye for the first time in my life I'd have "perfect" vision in 1 eye result of this would be no longer able to wear glasses as the difference between both eyes would be too great for brain to deal with leading to double vision/blurred vision solution would be contact lens for right eye and possibility of private treatment at a future date to have right eye fitted with IOL.
4: Got offered treatment at brand new specialist eye hospital with no waiting list - jumped at the chance - saw new surgeon 2 weeks ago. It didnt go well - we have language issues which hasn't helped - had BOTH eyes re-examined thoroughly again, got told without any warning or suspicion that I had a tumor in the right "good" eye - resulting BP reading was 166/98

5:Consulted my regular optician concerning contact lenses had yet another full set of eye tests, confirmed presence of "tumor" in right eye but also was able to explain in plain English what it actually was i.e. a "freckle/mole" very common and completely benign (will be monitored for any changes but not worth worrying about may never ever change or require treatment) similarly cataract in right eye is only "just" there and wouldn't normally even be commented upon as it has no affect on my sight at present and wont for a goodly while. Assured new technology now means I can have contact lenses for long term use. Confirmed wont be able to wear glasses post op due to huge difference between eye prescriptions.
6: Started a lens trail last Monday - the first set of contacts were far too strong resulting in very blurred vision close up, was unable to see anything closer than about 100' away from me. Got new less powerful ones on Wednesday which are great for distance but still utterly useless for close up. Then got told my surgery is scheduled for 4th March so no time to sort out lens before surgery.
As I understand it until I have the surgery we cant do anything about the reading issue and after surgery I'm probably going to have to try mono lenses - one lens for distance one for reading - but I cant even get my eye tested until after surgery and then I wont be able to wear a lens in that eye until the eye has healed, so there's going to be an unavoidable time lag where my eyes wont work together properly. It means I cant work - which is an anxiety all of its own as I only get paid for the work I do so no work = no pay I have come up with a possible work around of my own take the fixed eye out of the equation by wearing a patch on that side and wearing my current glasses around the house so at least I can function normally until it all gets sorted out, whether it'll work or not remains to be seen but if it does at least I wont go stark staring mad whilst waiting for a more permanent solution.

So depending upon whether or not the patch will help and indeed whether they'll allow me to even use it I may be unable to use the pc after Friday until the lens' get sorted out.
