Drysdale Nucleus Manipulator – 12.5 cm | Ophthalmic Instrument

Drysdale Nucleus Manipulator – Precision Ophthalmic Instrument

The Drysdale Nucleus Manipulator is a specialized surgical tool that ophthalmic surgeons use during the phacoemulsification phase of cataract surgery. The instrument allows the surgeon to rotate and dial the hardened lens nucleus into a more favorable position for emulsification, reducing the need for excessive ultrasound energy and protecting the zonules.

The instrument features a fine, angled tip designed to engage the nucleus gently. Furthermore, the angled shaft allows the surgeon to reach the nucleus comfortably while keeping their hand out of the visual axis under the surgical microscope. The 12.5 cm overall length and round handle provide excellent balance and secure grip during microsurgical maneuvers.

Because the instrument is often paired with other tools (such as the Sinskey hook) in cataract sets, it is a standard component of the ophthalmic surgical tray .

Key Features of the Drysdale Nucleus Manipulator

• Angled tip for precise nucleus engagement and rotation

• Angled shaft for improved visibility and ergonomic hand positioning

• 12.5 cm overall length for optimal control in the anterior chamber

• Smooth, round handle for a secure grip and easy rotation between fingers

• Surgical-grade stainless steel construction for durability and corrosion resistance

• Reusable and autoclavable for repeated clinical use

Medical Applications

Surgeons select the Drysdale nucleus manipulator for cataract surgery, specifically during nucleus disassembly and rotation techniques. The angled tip allows the surgeon to safely reposition the nucleus or dislodge it from the capsular bag.

Because capsule protection is critical during cataract surgery, the fine, rounded tip helps prevent accidental tears. For related instruments, explore our Ophthalmic Instruments or view our Lester Nucleus Rotator.

Durable Stainless Steel Design

Manufacturers construct the instrument from surgical-grade stainless steel, which resists corrosion and holds up across repeated sterilization cycles. The fine, angled tip maintains its shape over time, ensuring reliable performance for nucleus manipulation. (Learn more about phacoemulsification from Wikipedia).

Handle the instrument carefully to protect the fine tip, as even slight bending can affect the precision required for safe nucleus manipulation.
