Hello,

Contura vision is the most advanced blade free topography guided laser.

It is detectable by Corneal Topography and slit- lamp (Highly defined end ) examination

These are expensive and are available at highly equiped institutions.

It is very hard to detect in medical evaluation by simple examination methods.

It can't be detectable in NDA, because it is only detectable by highly equipped devices, which are not found in medical evaluation facilities of Army, navy or any defence sector

Hope it helps
