Necessity , they say the mother of invention. And Indian doctors have been quite creative when
hamstrung by few or no tools to perform specific surgeries. They simply design it themselves at one
fourth the price they are sold abroad. In fact, some of their innovations are priced at as much as
hundreds of dollars abroad.
Take 47 year old Dr Burjor P Banaji, pioneer of Lasik surgery in India. He’s invented over a dozen
surgical instruments. When this senior eye surgeon at Max Eye Care started Lasik, there were few
surgeons doing it worldwide and no specific instruments were available either. “As I want things
super-perfect, I designed a whole slew of instruments that made my surgery more efficient,” says
Banaji. The most popular instruments are Banaji Lasik Shield and Banaji Lasik Spatula and Canulae.
“It was simple. I had the designs in my head. Putting them down on paper was the simplest thing”,
he says. Instrument manufacturers and large multinationals in the US snapped them up. “They
would send me computer generated drawings which I would correct and send back. Their level of
execution was astounding. Within two weeks of the designs being finalised, the instruments were in
the world market.
His instruments are priced at hundreds of dollars each in the US and are sold in Switzerland, South
America, Korea, Eastern Europe, Africa and Japan. They are available in India at a fraction of the
price.i.Why have some Indian doctors created their own surgical tools?
