What Is an Ophthalmic Knife?
An ophthalmic knife is a microsurgical blade used to create precise incisions during eye surgery. Ophthalmic knives are commonly used in cataract surgery, anterior segment surgery, and other ophthalmic procedures where incision size, control, and consistency matter.
The correct knife depends on the procedure, incision size, blade design, surgeon preference, and facility workflow.
Main Types of Ophthalmic Knives
Slit Knife
A slit knife is commonly used to create the primary clear corneal incision in cataract surgery. Slit knives are available in different widths to match the surgeon’s incision preference and technique.
Trapezoid Knife
A trapezoid knife is designed to support controlled incision architecture. Trapezoid blade designs may help create consistent wound construction depending on the surgeon’s technique.
Paracentesis Knife
A paracentesis knife is used to create a smaller side-port incision. Side-port incisions provide access for instruments during cataract and anterior segment procedures.
Stab Knife
A stab knife is used for small, precise entry incisions. These knives are commonly used in anterior segment surgery workflows.
Crescent Knife
A crescent knife is used for lamellar dissection or scleral tunnel creation, depending on the procedure and surgeon preference.
MVR Knife
An MVR knife is used when a precise microsurgical entry is needed. MVR knives are often included in ophthalmic stainless steel knife portfolios.
LRI Knife
An LRI knife is used for limbal relaxing incisions. LRI procedures require control over incision placement, depth, and repeatability.
