I also had an operation for my eyes in 2011,it was not from the diabetes, is was just that they were leaking,and a bit of a nuisance,as i had to keep cleaning my glasses when the eyes were watering all the time,anyway that turned out to be a bit of a disaster for me,the reason being,they let me out the hospital the same day as i had the operation,when it was schedueled for me to be released the following day,i guess short of beds ,anyway 3 hours after being released i was back at the hospital as i was doubled up with pain, as i could no empty my bladder,even though i had a real bad sensation to go,at the hospital they just checked my bladder with one of these scanners they use,which i found out later, they are not the most reliable things for results ,what they should have done was insert a catater ,as i was in urine retension,any way it resulted in me going off my food could not eat at all,for 2 weeks result i lost 2 stone in weight,and eventually was rushed to hospital on an emergency, as my kidneys were not flushing properly ,my pulse was ar 145, finnished up having to wear a bag and self caterizing my self for 6 weeks,while all this was going on, they decided they wanted to check my prostate ,even though i previously had never had any problems what so ever, with my water works,anyway after the checked they said you have an enlarge prostate ,and wanted to go in there to see what was going on ,if i knew what i know now, i would have waited and went on the wait and watch program, as when they went in and found cancer cells,well i found later that even though they found cancer cells ,they cant tell wether they are fast growing or slow growing,and i also found that if they are slow growing, they can take a decade to flare up,and thats why i say i would probably would have chosen the watch and wait a specially at my age,but when you are told you have cancer cells, ,it scared the life out of me ,and i decided to go for the radiatuion treament and homone treatment ,and believe you me the side and after effects i got was unbearable,all i am trying to tell you is to be careful. regards making deceisions and,and get a 2nd opinion if you have any doubt as to whats going on,
