in my experience i can tell you my dad backround.he is diabetic,hipertension,blocked heart veins (almost 3 of them 97 %) and he is 73 years old.he had FACO both eyes succesfully by dearest Dr.Shamma in Hamad Hospital.She is a Qatari doctor.And she is treating all the patients like they are from her family.God bless this young lady and her team.They are well educated and trained abt it.More over,the same they when dad had surgery there were several patients that waiting their turn including a boy who was just 6 and a newborn!!

get well soon for your bro.
