What is the difference between these two Ciba products? I used Aosept for\nyears until it was taken off the market. Now supposedly it is back, but I\ncould only find Clear Care, which seems about the same. When Aosept was\nunavailable I used Ultracare, which I didn't like at all: you needed to add\nlittle tablets to the container each night, and the number of tablets never\nequaled the amount of solution. Since you can only buy the solution with\nthe tablets and a new container, it seemed very wasteful in addition to\nbeing annoying. So, now I'm using Clear Care.
