viscodissection
Surgical technique using viscoelastic substances to separate and protect ocular tissues during surgery.
Full Definition
Viscodissection is a microsurgical technique that employs viscoelastic materials (such as sodium hyaluronate) to create space between tissue planes and provide protection during delicate ocular procedures. This method is commonly used in cataract surgery to maintain anterior chamber depth, protect the corneal endothelium, and facilitate safe manipulation of intraocular structures. The viscoelastic material acts as both a mechanical barrier and a lubricant during surgical maneuvers.
Usage
Usage note: Distinguish from simple use of viscoelastic - this specifically refers to the dissection technique.
