sclerectomy 

Surgical removal of a portion of the sclera performed in glaucoma surgery. A common procedure is to make a conjunctival flap at the limbus, followed by a full thickness scleral opening and iridectomy.
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.

sclerectomy

1. excision of part of the sclera.
2. removal of sclerosed parts of the middle ear after otitis media.

Other surgical options may also be considered for patients unsuitable for medical therapy, such as tube shunts, viscocanalostomy (causing dilation of Schlemm's canal) or a deep sclerectomy (resulting in removal of the inner wall of Schlemm's canal and the juxta-canalicular trabecular meshwork alleviating the majority of outflow resistance).
A number of variations including changing the size, shape, and position of the sclerostomy and trapdoor, limbal, or fornix based conjunctival incisions, and altering the method of performing the sclerostomy by trephination, sclerectomy and the use of a scleral punch have been introduced.
The book's eight chapters cover trabeculectomy, mini glaucoma shunt, posterior drainage device, deep sclerectomy, gonioscopic surgery, canaloplasty, combined surgery, and lens surgery in glaucoma.
Some ophthalmological surgeries, such as, flap extraction, that is, removal of a cataract by making a flap in the cornea, antiglaucomatous sclerectomy and dacryocystorhinostomy are fraught with profuse hemorrhage exhibiting dependencies on changes in hemostasis parameters, including prothrombin time, thrombin clotting time and number of platelets.
