Micro-Surgical Precision

Malyugin Ring Pupil Expansion

Engineered for gentle tissue management during small pupil cataract surgery. Delivering atraumatic eight-point pupil expansion with single-use sterile clinical consistency.

Clinical Advantages

Gentle Tissue Architecture

Designed to minimize intraoperative miosis and sphincter trauma while maintaining clear surgical visualization throughout phacoemulsification.

Equally Distributed Tension

Micro-Incision Compatible

Pure Polypropylene

Eight rounded contact points balance iris tension evenly across the margin to prevent tears and minimize postoperative sphincter damage.

Deploys smoothly through standard 2.0 mm clear corneal incisions using a dedicated single-use inserter cannula.

Manufactured from medical-grade 5-0 polypropylene for consistent elastic memory, gentle tissue contact, and easy anterior chamber maneuverability.

Four-Scroll Engagement

Atraumatic Removal

Retract the sterile ring into the injector cannula under microscopic control using steady linear slider tension.

Advance the cannula tip through the main incision and position the distal scroll onto the far iris margin.

Engage side and proximal scrolls sequentially to achieve a stable 6.25 mm circular aperture without capsule contact.

Disengage scrolls with the dedicated hook and draw back into the cannula cannula post-phacoemulsification.
