Performing aqeeqah for an adult

Q: Because of some reason, Aqeeqha wasn't performed for my brother. He is 35 years old now. Can Aqeeqha be done now at this age by his father? Also, should we shave his hair at the time of slaughtering? If yes, may I know the order of slaughtering and shaving his hair? Should we shave this hair or remove little amount of hair? Please tell. What is the procedure of aqeeqha in this case?

Wazifa for eyes

Q: I have a new born baby boy who will be 4 months insha Allah after 2 days. He can look but not focusing and Allah forbid, doctors are saying that he might have albinism. Please suggest something so his eyes can focus.
