In most cases, glaucoma can be controlled with drops or laser. For some people though, the eye pressure cannot be effectively controlled, and surgical intervention is required. The traditional glaucoma surgeries (trabeculectomy and glaucoma drainage devices) are usually very effective, but they carry risks of blurred or even loss of vision, due to infection or a haemorrhage in the eye, low pressure and failure. As a result, even until today, some ophthalmologists delay glaucoma surgery, by using maximum medical treatments which can cause a number of topical and systemic side effects. This also results in worsening of their glaucoma. However, over the past few years, there is a plethora of novel surgical procedures and devices, claiming that they can reduce the eye pressure safely with minimal risk. The term MIGS is used to include all these surgical innovative techniques.
