Collar Buttons

The Graether collar button is used during cataract surgery to engage and reposition the pupillary margin, supporting iris stretching and pupil enlargement when a small pupil compromises visualization. A straight shaft delivers the button head into the anterior chamber through a paracentesis. The round knurled handle gives the surgeon controlled rotational purchase.

Features & Benefits

• Collar button head for iris margin engagement
• Straight shaft enters via paracentesis incision
• Round knurled handle for rotational control
• 121mm polished length suited to anterior segment work

Graether collar buttons assist iris retraction and pupil expansion during cataract extraction with small or bound‑down pupils. The 45 degrees angled shaft, with a 10mm segment from tip to bend, allows the button head to hook the pupillary margin without crowding the corneal dome. A round knurled handle preserves rotational orientation across the 115mm length, supporting steady positioning while the second hand works through a paracentesis.

Features & Benefits

• 45 degrees shaft angle clears the corneal dome
• 10mm tip‑to‑bend segment engages the pupillary margin
• Collar button head supports pupil expansion safely
• Round knurled handle preserves rotational control

The Micro Graether collar button with 45-degree angled shaft and 10mm paddle provides precise anterior segment tissue manipulation. The angled configuration supports ergonomic access for varied surgical approaches during complex anterior procedures.

Features & Benefits

• Angled 45-degree shaft for ergonomic positioning
• 10mm paddle supports anterior segment control
• Reliable tissue manipulation and retraction
• Durable construction for repeat clinical use

This Osher Malyugin collar button manipulator features a 10mm angled bend at the tip, allowing bimanual iris retraction and pupil dilation during cataract and intraocular lens surgery. The round knurled handle provides secure purchase and tactile feedback during delicate iris manipulation. At 118mm length, it reaches deep into the anterior chamber while maintaining surgeon control.

Features & Benefits

• Angled 10mm tip for ergonomic iris manipulation
• Round knurled handle for reliable grip during procedure
• 118mm length optimizes anterior chamber access
• Designed for bimanual pupil dilation and iris work

The Osher‑Malyugin angled collar button manipulator provides anterior segment globe positioning and mobility during ophthalmic surgery. Its 10mm tip diameter supports stable grasping of the sclera or surgical capsule without excessive forward pressure. The angled geometry maintains clear visualization of corneal and conjunctival work zones throughout the procedure.

Features & Benefits

• 10mm angled tip for secure globe fixation
• Anterior chamber access with controlled positioning
• Round handle supports stable surgical grip
• Stainless‑steel construction built for reliable reprocessing
