In incisional surgery, also called filtering surgery, a tiny drainage hole is made in the sclera (the white part of the eye) in a procedure called a trabeculectomy or a sclerostomy. (glaucoma.org)
Anterior chamber opening/sclerostomy: A trabeculectomy punch (eg, Kelly) is recommended for more precise and controlled excision of the corneal block (sometimes inaccurately called the trabecular block) but this step can also be performed using forceps, a blade, and Vannas scissors. (medscape.com)
MIMS® is designed to create a sclerostomy similar to trabeculectomy, the gold standard for incisional glaucoma surgery, but with an approach that is less invasive, in terms of tissue damage, and without any implanted material (stent-less). (sanoculis.com)
[1] DMD has also been reported in other surgeries such as keratoplasty, pars plana vitrectomy, iridectomy, trabeculectomy, laser sclerostomy and viscocanalostomy. (eyewiki.org)

A spatula is placed from the anterior chamber through the trabeculectomy sclerostomy into the subconjunctival space. (willseye.org)
