Hi there

My dad is suffering from the above as we just found out, he has had some sight problems but we thought it was a cataract and dint pay much attention, he is also a hig diabitic patient as well. We just saw an eye specialist in Lucknow, U.P, India ,he said that there is a possibity of losing the eye sight in one of the eye which has reached stage 4 but after doing laser treatments there is a possibilty that they can save some sight by doing an opeartion but its a risky operations as in some cases you can lose the eye sight completely and in some cases u can save it and in the other eye, as it is in stage 3, some sight can be saved. He did ask us to go for a second opinion, can someone guide me as to what needs to be done? I just dont know what to do and some guidance would be greatly.

We are from Uttar Pradesh, India.
