Dear Angel,
         Is this an artificial lens implant that is inserted during 
cataract surgery?  There have been numerous problems with bacterial growth 
with these implants.  It was theorized that the design of the lens implant 
was partly responsible for the bacterial growth and when a textured surface 
was added to the design, the bacteria was eliminated.  Again, it was 
theorized that the textured surface promoted quicker cellular attachment.
         Hope you find this useful,
         Linda
