corneoscleral incision
Surgical incision made at the junction between the cornea and sclera, commonly used in cataract surgery.
Full Definition
A corneoscleral incision is a surgical cut made at the anatomical junction between the cornea and sclera, typically at or near the limbus. This type of incision is frequently used in cataract surgery and other anterior segment procedures because it provides excellent access to the anterior chamber while maintaining structural integrity. The incision can be self-sealing and offers good wound architecture for healing. The precise location and construction of the incision affects surgical outcomes and postoperative astigmatism.
Usage
Usage note: Specify size in millimeters when documenting; distinguish from purely corneal or scleral incisions.
