IZHV: Iridozonular hyloid vitrectomy and Floaterectomy by Steven G. Safran MD

This is a patient with chronic aqueous misdirection after cataract surgery. She has a myopic outcome due to the anterior effective IOL position, glaucoma, a shallow anterior chamber and she is bothered by cloudy, turbid vitreous opacities that interfere with her vision. We have decided to do a pars plana vitrectomy to remove her floaters and to create a unicameral eye to solve her aqueous misdirection related issues. Here a 3 port PPV is done and we place our trocars only 2.75 mm back from the limbus (rather than the normal 3.5mm or so) as this is a 21mm eye and we want to stay more anterior to be safe as the pars plana may end a bit more anterior than normal in these shorter eyes. After a core vitrectomy all the anterior vitreous is removed in the area we want to make our communication between the anterior and posterior segment and the infusion is switched to the anterior chamber to deepen it for creation of an iridectomy. After the iridectomy is done the vitrector is then used to remove a small portion of the peripheral capsule to create uninterrupted flow between the different chambers of the eye.
