BLIND IN RIGHT EYE following Cataract Surgery?!

(Note: This story is in brief only) -I am 63 years old today. In 2007 I was diagnose diabetic and with BP symptoms thus was put on tablet since then. Later I developed slight central distortion in my right eye and had some difficulty in reading small close-up letters and faced difficulty in miniature drawings such as “stamps” designing. Otherwise my eyesight was perfect in both eyes. I got my driver licence and was driving perfectly well in the night. But for the distortion vision, I wanted to get eyeglass made and went to an Optometrist who advised me to that I had cataract /central distortion/macular endema in right eye. He referred me (with letter) for treatment at Govt Hospital. I gave the letter to Ophthalmologists at the hospital and personally explained them (drawing) about the slight distortion in my R/eye. Doctors investigation started from July 2009 and by May 2009 Retinal Specialist diagnosed me with cataract in my both eyes and sent me for cataract surgery on 01/09/2010.
Prior to surgery they didn’t take my consent or explained me the risks of Cataract surgery. My Path –lab blood tests records for the past 2 years indicated an average glucose level of 4.42 and my GP was very impressed. On my operation day my glucose level was 5.5 and BP was above normal (145/178 approx.). Usually it was between 120- 130 upon 65 -75.
I had day surgery on 1st Sept, 2009 and was sent home the same day specific methos of using eye drops.
During my post operation clinic the Surgeon told me that my surgery was successful but he told me that some kind of steroid injection in my eye to settle inflammation; which would cause some irritating effect but he didn’t tell me exactly what it was. I believe I was also given anaesthetic- but I am not sure whether it was an injection or something else. However, the doctor also told me that I would experience some disturbances in my vision for a few days or may be a week or so before everything would be normal again and advised me to continue putting eye drops every 4 hours. By evening on that day as the effect of anesthetic was gradually diminishing, I began feeling severe pain back of my eye. First time when I opened my eyed to put drops I saw a bug (image) floating in my eye which shocked me, BUT I thought since the doctor had already told me that I would feel some vision disturbances for some time; I took it easy. So since then I continued seeing a floater (Bug) in my eye but there was no sign of getting normal vision as anticipated. I got very worried about the internal pain in my eye and the gradual loss of vision.
So in frustration, I went to my GP who referred me to an Optometrist to examine my eye. On 15/09/2010 I saw an Optometrist and she told me that I had PVD which required urgent attention for further test and treatment. She gave me a letter and told me to go back to hospital Eye EMERGENCY OPD as soon as possible.
Next day (16/09/2009) I went to emergency OPD and the Eye specialist examined my eye very briefly and told me that my conditions were due to the Steroid injection and there was nothing to worry about. He told me to come back on 04/10/2010. I returned home without anything done to my pain in my eye. After two weeks (04/10/2010), I again went back to Specialist for normal review. He saw my pressure was high in my right eye and prescribed me new drops. When I asked him what happened in my eye, he told me to ask him the question again after one month (4/11/2010). I was really devastated by his response. Me and my wife who is a Rheumatoid arthritis patient, both cried.
However, Two weeks later suddenly I started seeing more floaters in eye, flashes, glares, shades etc which really rocked me. I lost almost 99% vision. I didn’t know what was going on because the doctor never told me that such thing would happen. By the time I saw the specialist I was almost blind. I saw an eye specialist on 28/10/2010; who told me I had couple serious problem at back of my eye and in his report he wrote- my vision was down to PL in r/eye and since I was a Diabetic, I had Diabetic Retinopathy- he said “in the Triamocinalone crystals in vitreous with further Vitreous Opacification. Also ..Membrane with some pigmentary change and suspected to have CMO / CME. He told me to go back to hospital again.
So two days later (2/11/2010), I saw second specialist, he said.... acuity was poor les than hand movement.....featureless looking fundus on the right with scattered peripheral haemorrhages... ..some type ischemic event has occurred peri operatively.....advised to go back to hospital
On 4/11/2010, I was seen by the Surgeion who did my surgery at the hospital. He described my condition as "mysterious". They asked me to get Flourecene Angiography and AVASTIN test done but I declined since they posed serious side-effects such as fatalty; associated with cardiovascular problems; resparatory problems etc. The doctor told me to get blood tests so I did on the same day and
