Description
Sichel Corneal Knife
The Sichel corneal knife takes its name from Jules Sichel, a 19th century Paris eye surgeon. This 13 cm reusable steel blade is for fine corneal incisions. It suits surgeons who like a classic outline and a longer handle.
A Paris Pattern
Paris was a hub of eye surgery in the 1800s. Many tools from that time still carry their makers’ names. The Sichel is one of them. So it is a fine choice for surgeons who value tradition.
Sichel Details
- Size: 13 cm.
- Role: classic corneal knife work.
- Steel that tolerates repeat steam.
- You sterilize it before first use.
Longer Handle, Steadier Feel
The 13 cm length gives more room for the hand. As a result, your fingers stay out of the microscope view. Some find it steadier too. However, if you like a shorter tool, look at our 12 cm options.
Microscope Working Distance
Under the microscope, space between lens and eye is limited. A 13 cm knife lets your hand sit lower and further back. Then your knuckles stay clear of the lens. It is a small detail that eases long cases.
Labels and Tray Maps
A tray map shows where each tool belongs. Mark the Sichel slot clearly. Also label any guard with the knife name. When staff restock, they then know the knife is back where it should be.
Sichel Beside Elschnig
Both the Sichel and the Elschnig come at 13 cm. So length will not decide between them. Instead, look at the blade outline and the handle. Then choose the one closest to the knife you trained on.

The Sichel ships unsterile; clean and steam it first. Then, between lists, the same care keeps it in service. Sichel orders hold three years against manufacturing defects, a pledge we stand by. The stainless steel we select meets the aims of ASTM F899. Browse the eye instrument section or the Elschnig 13 cm knife. Visit the FAQ area for help.
