Wilder Lacrimal Dilator 1 Set (3 Pcs)

Description of the Wilder Lacrimal Dilator The Wilder Lacrimal Dilator is a classic, finely-crafted ophthalmic instrument specifically designed for procedures involving the nasolacrimal system, particularly the lacrimal punctum. It is a staple in ophthalmic procedures for diagnosing and treating obstructive dry eye and excessive tearing (epiphora). Primary Function Its sole purpose is to gently and progressively dilate the punctal openings (the small, visible pores on the upper and lower eyelid margins) to allow for the passage of other diagnostic or therapeutic instruments. Key Design Features Slender, Tapered Probe: The defining feature of the dilator is its long, slender metal shaft that gradually increases in diameter. This smooth, gradual taper allows for controlled, atraumatic dilation. Bulbous, Rounded Handle: The instrument typically features a distinct, rounded, and often grooved or knurled handle. This design provides an excellent, non-slip grip for the surgeon, enabling precise control and minimizing the risk of slippage during the delicate procedure. Fine Tip: The very tip of the dilator is extremely fine, allowing it to be introduced into the tiny (normally ~0.3 mm) punctal opening with minimal tissue trauma. Material: It is almost exclusively manufactured from high-quality stainless steel, ensuring durability, resistance to corrosion, and the ability to withstand repeated sterilization. Size: It is a small, handheld instrument, typically around 4 to 5 inches (10-13 cm) in total length, making it perfectly suited for microsurgical procedures around the eye. The procedure for using the Wilder Lacrimal Dilator is meticulous and delicate: The surgeon stabilizes the eyelid. The fine tip of the dilator is inserted vertically into the punctal opening. With gentle, rotating pressure, the surgeon advances the dilator slightly, allowing the tapered shaft to stretch the punctal sphincter muscle and surrounding tissue. It is held in place for a few moments to achieve the desired dilation. Once the punctum is sufficiently widened, the dilator is removed, allowing for the next step in the procedure. The Wilder Lacrimal Dilator is essential for: Punctal Plugs Insertion: This is its most common use. The punctum must be dilated before inserting a punctal plug to block tear drainage and treat dry eye syndrome. Lacrimal Irrigation (Syringing): Before flushing the nasolacrimal duct with saline to test for blockage, the punctum must be dilated to allow passage of the irrigating cannula. Lacrimal Intubation: In procedures to stent the entire tear drainage system, the punctum is the first point of access and must be dilated. Probing the Nasolacrimal Duct: Used in both infants and adults to open a blocked tear duct.

• Purpose: Used to gently dilate (open) the lacrimal punctum—the small opening of the tear drainage ducts.
• Common Use: Typically employed during ophthalmic or ENT evaluations to assess or prepare the lacrimal drainage system.
• Design: A double-ended instrument, with each end having a slender, tapered, smooth dilating tip of different sizes.
• Handling: Designed for precision and control, allowing clinicians to work with delicate ocular structures
• Initial punctal dilation before probing or irrigation
• Aid in evaluating tear duct obstruction
• Preparation for inserting certain lacrimal devices (e.g., plugs or tubes)
• Used in clinical and surgical ophthalmology by trained professionals.
