Johnson and Johnson Vision UNFOLDER Emerald XL Delivery System | Legacy Advanced Medical Optics (AMO) Platform | Screw-Style Manual Lens Implantation Handpiece | Micro-Threaded Drive Shaft with Oversized Control Hand Wheel | 6.0 Inch Nominal Total Length (15.2 cm) | Reusable Capital Cataract and Refractive Micro-Surgical IOL Insertion Element | Pre-Owned Hospital Surgery Asset (1/EA)

The Johnson and Johnson (formerly Advanced Medical Optics / AMO) UNFOLDER Emerald XL is a professional-grade, hospital-level ophthalmic micro-surgical instrument expertly engineered to compress, guide, and inject foldable intraocular lenses (IOLs) directly into the capsular bag during cataract extraction procedures. Measuring approximately 6.0 inches in nominal total length, this premium reusable handpiece represents an engineering upgrade within the Emerald implantation series. The handpiece utilizes a precise screw-style manual delivery mechanism featuring micro-refined, closely spaced internal driving threads paired with an oversized proximal thumb wheel. This structural layout provides the anterior segment surgeon with highly linear mechanical force, preventing sudden lens lunging or jerky advancements through the single-use cartridge tip. By enabling a slow, uniform delivery vector, the handpiece permits the folded acrylic or silicone lens optic to deploy and unfold predictably inside the eye without overstretching unenlarged clear corneal phaco incisions as small as 2.6 mm to 2.8 mm. Forged from high-tensile, titanium or premium surgical-grade stainless steel components, this handpiece contains no interior electronic modules, rendering it fully calibrated to handle high-frequency ultrasonic clearing, manual lumen flushing, and strict dynamic steam autoclave sterilization cycles inside central sterile supply departments (CSSD).
