side view of blade tip
Blade bevel means whether blade is formed on both sides or blade is formed only on one side.
Blade that is honed on both sides is referred to as bi-bevel,
while blade is formed only on one side with the honed surface facing up is referred to as bevel-up,
and with the honed surface facing down is referred to as bevel-down.
Incision knife
The straight. ultra-sharp blade is precisely honed in micron units for optimum use in semilaminar incisions and centesis incisions of the sclera and cornea.
Groove knife
The stainless steel guard provided on one side of the 30°straight blade makes it possible to assure a consistent cutting depth for incisions in the sclera and cornea while also preventing obstruction of the viewing field during incision.
Furthermore the guarded depth feature of the ‘Groove knife’ makes it ideal for performing Limbal Relaxing Incisions(LRI).
Groove knife for Glaucoma surgery
The stainless steel guard of 0.1mm thickness provided on one side of the 30°straight blade makes it possible to assure a consistent cutting depth for incision in the upper half of the sclera.
Crescent knife
The blade design features straight sides and a round tip and is optimum for creating scleral tunnel flaps.
In addition, this knife is available in bi-bevel, bevel-up and bevel-down types to accommodate the needs of surgeons.
Round tunnel knife
The sharp, round blade edge is beveled on both sides,
gradually extending from the center of the circle,
and perfect for creating scleral tunnel flaps.
Slit knife（Flat Shaft Type）
This knife is used for sclerocornea centesis incisions during cataract surgery.
A choice of knives with keratome angles (40°,45°, 50° or 60°) and blade edge types (bevels) allows surgeons to make a wide range of incisions.
Slit knife（Round Shaft Type）
This knife is used for sclerocornea centesis incisions during cataract surgery.
Slit knife（Rib & R Type）
①Arrowhead-shaped curved edge reduces incision resistance
②Both sides of knife are thinly grinded (RIB shape)
Slit knife（Parallel Side Type）
This knife has a blade with chamfered side edges to facilitate smoother puncture into the sclerocornea, giving less tissue invasion.
Implant knife
This knife is used to widen the incision wound opening for implantation of an intraocular lens.
The trapezoidal shape of the blade tip enables it to be used safely.
Implant knife with guide
The stainless steel guide of 1.0mm width provided on the blade edge makes it possible to widen the incision maintaining the uniform depth without deviation.
MVR knife
This knife is used for centesis incision into the sclera during vitreous body surgery.
It is also used to create side ports during cataract surgery.
Scleral knife
This knife is used for making incisions in the sclera.
It is also used to create scleral flaps during glaucoma surgery.
