What is DM detachment?
Descemet’s membrane detachment (DMD) is relatively common, occurring in up to 43% of cataract operations[1]. Most are small, peripheral detachments at the site of corneal incisions and are clinically insignificant, resolving without further intervention.
Where is the incision for cataract surgery?
During a procedure called phacoemulsification (fak-o-e-mul-sih-fih-KAY-shun), your surgeon makes a tiny incision in the front of your eye (cornea) and inserts a needle-thin probe into the lens substance where the cataract has formed.
Which suture is used in cataract surgery?
Purpose: Corneal suture in cataract surgery is known as a significant factor for reducing post-operative endophtalmitis but may induce a transitional corneal astigmatism. Suture removal is usually performed postoperatively, making it possible for the cornea to take its final shape.
What is corneal incision?
Currently the most popular entrance site for phacoemulsification cataract surgeries and intraocular lens implantations. These clear corneal wounds usually are self-sealing, and do not induce astigmatism as they heal. They have minimal risk of bleeding.
What is Optical iridectomy?
An optical iridectomy is the surgical removal of part of the iris to enlarge the existing pupil, or to form an artificial pupil, when the natural pupil is ineffectual.
What are eye sutures?
Adjustable suture strabismus surgery is a type of eye muscle surgery that allows the surgeon to be able to fine-tune the eye muscle position in the immediate postoperative period. By being able to adjust the muscle position, a surgeon may be able to maximize the probability of successful eye alignment.
What are Y sutures?
This is a congenital lens opacity that occurs at the location of closure of the fetal lenticular nucleus. The anterior sutures are in the shape of a Y and the posterior sutures are an inverted Y. These are rarely visually signficant.
What is the Descemet’s membrane?
Descemet’s membrane- which is the basement membrane for the corneal endothelium- is a dense, thick, relatively transparent and cell-free matrix that separates the posterior corneal stroma from the underlying endothelium.
What causes Descemet’s folds?
Descemet folds are associated with corneal edema due to endothelial dysfunction from infections, from infiltrations, or following surgery. Descemet folds also are associated with corneal inflammation due to infections or infiltrations or following surgery.
