One the Eye Doctor's Im seeing now has recommended the Collamer single piece Nano-Flex by Staar. I have not seen much in MedHelp on this Iol. He told me that he would implant any lens I want. I just thought I would ask you Doctors to see if you have any knowledge of this Iol. The Iol I have in my left eye is the Crystalens HD500 Diopter 23.00. Thank you for your help. Dan
