Vas in mid 06 I bought AOS when it announced tetreflex was approved in 32 countries inc UK europe and Australia then in Nov 06 was approved in China. two years later royalties are only 70k and still no comment on any progress getting US approval when they were supposed to be selling in the US in '08. If it can only get 70k royalty when its available in half the world markets already then it doesnt sound like a winner. aos paid $US4mil for tetra so it'll take years to recover the cost price let alone any return on investment. Alcon and others already sell second and third generations of their advanced IOLs and tetra version 1 isnt even in the US market. lenstech looks like a little guy up against the market muscle of Alcon, same reason we hope TA will succeed but a reason tetra will struggle is too many big guys with their own products. If tetra was going to be a winner a big guy would of bought lenstec a few years ago or offerred to buy the IP from AOS so they mustnt see any threat to their own products. Hopefully TA will do better but for aos its one of only two product where for Alcon its just one of hundreds so its not that important to them. I'll hang on a bit longer but aos is boring, Oculis was yet another coostly failed venture and a tax loss against my mining profits will be useful in june.
