Minimally Invasive Glaucoma Surgery: MIGS

Minimally Invasive Glaucoma Surgery or ‘MIGS’ is a term applied to the widening range of implants, devices and techniques that seek to lower intra-ocular pressure with less surgical risk than the more established procedures.

MIGS has been defined as (intraocular pressure) IOP-lowering surgery with the following characteristics that distinguish it from traditional glaucoma surgery:

  • ‘Minimally traumatic’
  • Via an ab-interno conjunctiva-preserving approach
  • High safety profile
  • Rapid recovery
  • Frequently combined with cataract extraction
  • Provides more modest IOP lowering than trabeculectomy
