Donaldson Lacrimal Cannula

Donaldson Lacrimal Cannula is a specialized ophthalmic instrument used for irrigation and diagnostic evaluation of the lacrimal drainage system, including the puncta, canaliculi, lacrimal sac, and nasolacrimal duct. Designed for delicate lacrimal procedures, the instrument features a precision-crafted atraumatic tip that allows smooth insertion into the lacrimal passages while minimizing tissue trauma. The fine lumen supports controlled irrigation, enabling ophthalmologists to assess tear drainage function and identify partial or complete obstructions within the lacrimal system. The Donaldson design is commonly utilized during lacrimal irrigation procedures to evaluate the patency of the tear drainage pathways, confirm successful probing, and assist in the diagnosis and management of lacrimal disorders. Its slim profile provides excellent maneuverability and precise access to delicate anatomical structures. The instrument delivers reliable tactile feedback, allowing clinicians to perform both routine and advanced lacrimal procedures with enhanced control. Donaldson Lacrimal Cannulas are widely used during nasolacrimal duct evaluations, canalicular assessments, tear drainage investigations, postoperative lacrimal care, pediatric lacrimal procedures, and oculoplastic surgical interventions. Manufactured from premium surgical-grade stainless steel, the instrument offers exceptional durability, corrosion resistance, and dependable long-term performance. The polished finish promotes smooth insertion, consistent fluid flow, and efficient cleaning and maintenance. Available in multiple lengths, diameters, and tip configurations, Donaldson Lacrimal Cannulas can be selected according to patient anatomy, procedural requirements, and surgeon preference. Widely used in hospitals, ophthalmic surgery centers, eye clinics, ambulatory surgical facilities, and specialty ophthalmology practices, the Donaldson Lacrimal Cannula remains an essential instrument for lacrimal system diagnosis and treatment. Fully reusable and autoclavable, the instrument is designed to withstand repeated cleaning and sterilization cycles while maintaining lumen integrity, tip precision, and structural performance.
