Money isn't the reason players aren't getting it. Goberts eyes are probably still changing. Most people can't get it until mid to late 20s.
He's fine to get it at his age, early 20's is ok nowdays. The issue is more that with the way the incisions are made and the way the cornea heals, an injury like a finger poke is almost the only way that the cornea can be damaged post op, it can potentially dislodge the part of the tissue that is treated and be a real problem. If i was playing a contact sport like that there's no way i'd want it done. Contacts actually afford some protection.
