Hospital review. Clinic chennai.

My dad is a diabetic and is about to visit Aravind eye hospital where he treated earlier, he also intends to visit Velamal medical institute and research centre in madurai after hearing it's fame in terms of good treatment at low prices, but I couldn't verify any of those information and mostly look like fake news! His health is very important for me but I am not travelling along with him due to work compulsions, please provide some authentic information about this institution and whether the aforesaid news floating around is true or not! My dad would be travelling all the way from Andaman islands to madurai, so it a very crucial matter to decide! And also give review about dr mohan's diabetic clinic chennai. Thanks in advance!
