I personally think you should be not affraid, the time to get used to things is mostly not long. See it as an enrichment similar to "I am used to see VHS video and now I am looking at the rich details and colors of Blueray". The experiences stored inside you concerning your lack of vision will in part stay and some of it that is not important for the function of your system later on will be lost.
