Microsurgery is a blend of art and science, requiring steady
hands, excellent vision, and control down to a tiny fraction of a millimeter.
Among all the tools that surgeons trust, the Iris Curved Microsurgical Scissors
with tungsten carbide inserts stand out for their precision. These scissors
deliver the smooth, exact cuts that delicate operations demand and are found
everywhere—from ophthalmology and neurosurgery to plastic surgery, ENT,
vascular microsurgery, and reconstructive surgery.
Originally shaped for ophthalmic surgery, the Iris curved
design has matured into a tool that is vital in all fields requiring fine
manipulation. The tungsten carbide inserts in the blades add durability,
keeping the cutting-edge sharper for longer and resisting wear without
sacrificing accuracy.
In this post, we’ll dive into the Iris scissors. We’ll cover the thoughtful design, when and why they are used, the advanced materials, the comfortable grip, how to care for them, and why they are the cornerstone of success in modern microsurgery.
Iris curved microsurgical scissors are small, curved-bladed
scissors tipped with ultra-sharp edges and reinforced with tungsten carbide
(TC) inserts. These inserts keep the blades sharp longer and make them more
resistant to bending. First designed for eye surgery, they are now trusted
wherever surgeons cut delicate, blood-rich tissues and need flawless control.
Iris takes its name from early eye surgery, but
now they are used in every specialty.
Curved blades follow the natural curves of the
body for easier access and better sight of the target.
Microsurgical means the tips are tiny and the
handles are short, perfect for working under the microscope.
Tungsten Carbide Inserts are small, tough pieces
bonded to the edges, letting them slice smoother and stay sharp much longer.
Measuring only 3.5 to 4.5
inches in overall length, the instruments end in pair of extremely fine,
pointed tips. This small size lets a surgeon grab and cuts the tiniest
structures with little chance of harming tissues nearby.
Knowing how the scissors are
put together reveals why they work so well and remain a favorite in many
operating rooms.
The tips are finely pointed to
get into the smallest tissue spaces.
They are perfect for quickly
snipping sutures or cutting through tough, fibrous membranes.
The gentle curve of the blade
lets you see what you’re cutting and gives you better control.
This shape helps the blade
reach around curved or recessed parts of the anatomy.
Tough tungsten carbide strips
are built into the cutting edges.
They are over five times harder
than standard stainless steel.
This keeps the cutting edges
sharp through hundreds of uses, cutting down on re-sharpening.
The shank and shaft are slender
and long, letting you reach deep into narrow spaces.
The lighter design means
there’s less drag and fatigue during long cases.
The loops are shaped to fit a
gloved hand comfortably.
They often have a textured or
sandblasted finish to grip securely, even with fluid on the gloves.
The scissors are made of
high-quality surgical stainless steel.
Tungsten carbide is bonded into
the blade tips.
They can be fully sterilized and resist corrosion.
Iris curved microsurgical
scissors are favored in many fields for their pinpoint accuracy and outstanding
feel, making them ideal for delicate suturing, precise dissection of nerve and
vascular tissue, and cutting fine graft material.

Tungsten carbide is not just
another material. It combines hardness and durability that turns ordinary microsensors
into instruments you can trust for the most delicate tasks. Edge retention is
far beyond steel, meaning you spend less time re-sharpening and more time in
the operating room. The micro balance and inertia also allow effortless opening
and closing, so you can focus on the tissue, not the tool.
Scored at 9 on the Mohs scale,
only diamond ranks higher at 10.
Holds a cutting edge 5 to 10
times longer than even top-quality steel.
Endures repeated, rigorous use
without quick dulling.
Perfect for busy operating
theaters that depend on reliability.
Cuts are sharp, smooth, and
immediate.
Limits micro-tearing,
preserving tissue for better healing.
No micro-chips or jagged edges
appear over the months or years.
Precision is steady, whether
used daily or occasionally.
Corrosion Resistance
Stays stable against body fluids and every sterilant protocol.
Every microsurgical instrument
should feel like a natural extension of the surgeon’s hand. The Iris curved
scissors achieve this sensation with a graceful, well-considered profile.
The scissors are designed so
the center of gravity sits close to the finger loops. This keeps the instrument
steady, letting you make smooth cuts even during long procedures.
To get the most from the Iris
curved microsurgical scissors, you’ll need a delicate, practiced grip.
Keep the curved tip turned away
from vital structures to protect them.
Always bring the blade’s curve
upward to see the cutting line more clearly.
Use a tripod grip to steady
your hand and reduce shaking.
Use loupes or a microscope to
see and target specific tissue layers.
Close the scissors slowly in
stages, checking tissue tension at each step.
Never twist the scissors;
twisting loosens the hinge and ruins the tool.
Don’t cut through sutures that
are heavier than the blade’s intended capacity.
Avoid using the scissors on
bone, cartilage, or very dense tissue.
Don’t store the scissors alongside heavier instruments; the tips can bend or go out of line.
Like any precision surgical
tool, Iris scissors need regular and careful maintenance.
Rinse right after each use with
sterile saline.
opt for neutral-pH enzymatic
cleaners.
Use soft brushes on the hinge
and tips to clear away any stuck debris.
Autoclave the scissors at
121–134°C.
Avoid dry heat and ultrasonic
cleaners unless your facility gives specific approval.
Make sure the scissors are
completely dry after the sterilization cycle.
Store in padded trays or soft
silicone brackets.
Always fit tip protectors to
prevent accidental nicks or bends.
Don’t clamp the jaws shut
tightly; doing so can weaken the spring over time.
Look closely to confirm blade
symmetry and correct curvature.
Test sharpness on a piece of
tissue paper or film.
Wiggle the hinge to check for smooth movement and ensure the loop stays firm.
The Iris curved scissors with
TC inserts come in several versions so you can choose the one that fits your
specific needs best.

or stored in a crowded tray.
Users need a steady hand;
beginners may struggle.
Poor sterilization can dull the
fine edge.
