Ajay Sharma and Rajat Goel know Rewari well. While Sharma, an eye surgeon, has family roots in this largely agrarian town in Haryana, Goel, an IIM-A graduate, used to make marketing field trips here during his days with Bausch & Lomb and Godrej. But that’s not what makes the duo nostalgic as they step into Eye-Q’s two-storey building on a narrow and busy main road. Back in 2007, the Rewari hospital was literally the test bed to validate their vision for setting up a chain of super-speciality eye hospitals in small towns and cities across North India.
