Genslit® · Genslit® SKnife® · Genblade™
Precision-engineered blades and handle systems for accurate incisions, controlled tissue entry and consistent performance, manufactured at our ISO 13485:2016 certified facility.
Genslit® · flagship
Eyegen's premium ophthalmic micro-surgical knife pairs a sterile, single-use blade with a reusable PC handle system. It is engineered for precision, control and consistency in corneal and limbal incisions; use and reprocessing must follow the product IFU.
Genslit® family · depth-limiting profile
Genslit® SKnife® pairs the precision blade and PC handle system with a safety-stopper profile designed for controlled corneal entry during phacoemulsification and ICL procedures.
Single-use handle · volume programs
Built on the Genslit® blade engineering platform, Genblade™ pairs the precision blade with a single-use PP handle and U.S. surface technology for high-volume programs and price-conscious buyers.
Why Genslit®
Genslit's performance comes from three areas working together: the blade itself, the finish applied to it and the handle system that holds it.
Medical-grade SS 420 with uniform thickness across the cutting zone supports repeatable bevel geometry and avoids the thickness variation often associated with manually forged blades.
Advanced manufacturing equipment forms consistent edge geometry, bevel angles and incision dimensions from blade to blade.
“True sharpness is not aggressive entry, but controlled cutting throughout the incision.”
The Genslit® double cutting-edge design is intended to support controlled advancement from entry to exit.
Precision that reduces penetration force
Independent thickness measurement shows Genslit's bevel holding a consistent sub-150 micron profile, while manually ground blades typically show greater variation along the same edge. A thinner, more consistent bevel meets less resistance and may help minimise crush and trauma at the wound edges, supporting a clean, watertight, self-sealing incision.
Comparative performance statements should be supported by current, approved test data.04 / The finish
Specialised surface treatment is designed to minimise tissue drag. An anti-glare surface reduces reflections under the operating microscope to support visual clarity at the incision site.
05 / The handle system
Ultrasonic welding mechanically bonds the blade to the handle rather than relying on a glue-based attachment, helping maintain alignment under surgical force. Colour-coded handles distinguish Keratome, Crescent, Side-port and MVR variants.
Genslit® configurations
The same Genslit® blade is offered in four configurations, each suited to a different step of the procedure.
Primary corneal or limbal incision for phacoemulsification and cataract surgery.
Scleral tunnel or flap construction, supporting a stable, self-sealing wound.
Secondary paracentesis entry for instrument access and anterior chamber stability.
Vitrectomy access - a fluid-tight stab incision for posterior segment instruments.
