Minimally Invasive Glaucoma Surgery
• Pre-operative gonioscopy is mandatory for selecting appropriate patients.
• The irido-corneal angle view is optimised when the patients' head is tilted away and the microscope tilted toward the surgeon with a combined angle of 70-80 degrees.
• Under filling the anterior chamber with visco-elastic makes intra-operative gonioscopy difficult.
• Avoid limbal blood vessels when positioning the corneal incision as bleeding will obscure the view.
