deep sclerectomy A type of non-penetrating filtration surgery aimed at lowering intraocular pressure by dissecting a superficial scleral flap and excising a deeper partial thickness scleral flap below leaving a thin membrane consisting of trabeculum and Descemet's membrane through which the aqueous humour diffuses. It then drains from the anterior chamber to the subconjunctival space or though Schlemm's canal. A collagen implant is usually inserted under the superficial flap to improve drainage of aqueous humour.
