If the poor can't get prenatal care while the rich can have their babies vision repaired in utero (ok, I am talking out of my behind there, but it's quite likely possible) there is a problem.
Only for the poor. And there's no more of a problem than there would be if advanced medical care was not available to the rich. Those who can afford the latest medical treatment should surely be allowed to avail of it to give their children the best start in life. Those who cannot afford prenatal care might be better advised to use contraception.
