@Azuza - Those things would be hard for someone with untreated aphakia. However, a person with treated aphakia could live life normally!
A friend of mine has a 10 year old daughter who was born with aphakia. They opted to get her lens implants and it totally corrected the condition. They were a little bit scared of the surgery at first, but it went very well. If I remember correctly the recovery time was pretty short too.
