SLT
First of all, there's no need to do anything until your intra ocular pressure, IOP, becomes elevated. Check the IOP at your optometrist who will advise on how often you need the check.
Drops will reduce IOP for a time.
Selective Laser Trabeculotomy takes out individual cells in your iris to increase drainage.
DO NOT accept argon laser which blows big holes in your iris. SLT is the new standard of care.
