Most the information I read gives me the same info as you replied to my question, the optic diameter of Tecnis One is 6mm.
However, there is an article published by Dr Quentin Allen cited that the edge design of the Tecnis One doesn't fully utilize the 6mm optics and the actual effective optics diameter is only 5mm. His description is on the page 11 of the document http://www.crstodayeurope.com/Issues/0109/crste0109_supp.pdf. I understand Dr Allen is a paid consultant from Alcon.
I just want to see if you known any research of the EFFECTIVE optics diameter related to the edge design of the IOL.
BTW, I saw some news about a class 2 recall of Tecnis One from Abbott. Is it just a minor issue ?
