"Incomplete treatment"

For I hear the ophthalmic dept battled to save my son's last eye. This I can say the consultant was excellent. Hence his original consultant came back after being off a year. This consultant suggested that after being on steroid drop for his eye every 2hrs. So we are sent home and was told he'd get an appointment in 6 weeks. My son has now began to lose his sight, cannot see his feet. I telephoned the appointments and was told he is on the waiting list. How can you be on a waiting list when there is ongoing treatment!?My son will be totally blind by the time he gets an appointment, he's in this mess because a cataract operation gone wrong! He needs to restart the medication and furthermore the consultant knew he wasn't getting an appointment for a least 6 months
