As a parent, I get the emotional reaction. You want to provide the absolute best for your child, and this feels like a total missed opportunity.
But as someone who had cataract surgery as a newborn, please don't fret about it too much. I don't know how old your son is or when his surgery was, but bilateral aphakia is something that has become more of an inconvenience than anything else. It certainly shouldn't limit his options in life. (Unless his heart is set on joining the military, like I was. But, as they say, I really dodged a bullet there.)
