Angle-based Minimally Invasive Glaucoma Surgery (MIGS) What is Angle-based Minimally Invasive Glaucoma Surgery (MIGS)? Angle-based MIGS are procedures which enhance the natural outflow pathway of the eye, or the “angle” (Figure 1), where eye fluid normally drains out. This helps to reduce eye pressure.

These surgeries involve either the implanting of devices, or the removal of tissue from the angle of the eye. In general, angle-based MIGS may not be as effective in reducing eye pressure as compared to traditional glaucoma surgeries or other forms of MIGS. However, they are less invasive procedures and also have a better safety profile. In addition, no anti-scarring medications are needed for these surgeries. Hence, there is no risk of side effects associated with these medications.
