Glaucoma diagnosis

I really am asking for a friend! My friend was recently referred to hospital as the pressure was raised considerably in each eye. I think it was 20+ in each eye. She's been given drops and is waiting for an appointment to discuss laser surgery. She's also had to inform DVLC but hasn't had to surrender her licence as yet. She lives on her own but does have grandchildren who she helps to look after. She is quite frightened about the future and I didn't have any knowledge of the condition so I wasn't really in any position to offer much comfort. Has anyone had experience of this, especially the laser treatment? Very grateful for any replies.
