Staar Collamer Aspheric Lens

I have been researching lenses preparatory to cataract surgery. The Staar lens interests me because it is said to repeal protein and, presumably, opacification. Has anyone had experience with this lens? I can't find information on a downside, but every lens seems to have one. And what is the differenced between a 1-part and a 3-part lens? I have the beginnings of macular degeneration in my left eye and acuity is 20/100 for the left, and 20/50 for the right. No astigmatism. I am 80 years old and in excellent health.

I meant to say, "repel protein."

I stopped using it due to a high incidence of posterior capsular opacification. It is not used much by most surgeon I know.

Once again, many thanks.

Hi Dr. Oyakawa, does this mean that the staar lens (Nanoflex?) have a higher incidence of posterior capsular opacification?
