In the past 10 years there has been a growth in the use of minimally invasive glaucoma surgery (MIGS) to treat the condition. 

Professor Gus Gazzard, Consultant Ophthalmic Surgeon at Moorfields Eye Hospital, defines a MIGS procedure as “one with quick recovery, short operating time and lower risk”. Such a procedure, however, also “lowers the pressure less than traditional forms of operation like a trabeculectomy, so may have a lower chance of success in more advanced cases”.
