the same high volume/low margin model has been applied to hit target costing in other areas. For example early operations often involved fitting an 'intra-ocular lens' which was manufacture within a division of Aravind - Aurolab - now means thay the IOLs can be made for a fraction of the import price ($6 vs. $100-$150 for a US made lens of the same quality). In the process Aurolab have become a major producer with about 10% of the global market share.
