Sinskey Hooks — Pattern and Clinical Use
After an IOL is injected into the eye it must be rotated so its haptics sit correctly in the capsular bag. The Sinskey hook engages the lens optic or a positioning hole and dials it into place. The same instrument is used to manipulate the nucleus during phacoemulsification and to free adhesions, making it one of the most-used instruments in cataract surgery.
The hook tip must be fine enough to engage a positioning hole but blunt enough not to mark the lens optic or catch the posterior capsule. Tip radius is the defining specification.

Material, Finish and Quality Control
We forge Sinskey hooks from 316L austenitic stainless. Tip radius is gauged so the hook engages a positioning hole without marking the optic or catching the posterior capsule. Each batch passes Rockwell hardness testing, dimensional checks on tip radius and finish, and visual inspection under our ISO 13485 system before passivation and final finishing. Mirror and satin finishes are both available — satin is usually specified where glare under operating lights is a concern.
Who Sources Sinskey Hooks From Surgical Star
Sinskey hooks are used in virtually every cataract procedure and are among the highest-volume ophthalmic micro-instruments, giving distributors a dependable repeat line.

Every Sinskey hooks can be produced as a private-label line: your logo laser-marked on the handle, your catalog numbers, and your own printed packaging, manufactured from your drawings or a reference sample. Production runs inside a documented ISO 13485 quality system, with CE marking under EU MDR 2017/745 and US FDA establishment registration behind it. Your shipment carries a certificate of conformity plus the ASTM F899 material certificate for the grade actually used.
Minimums stay deliberately low so a new brand can launch without a heavy first order, and pricing is quoted direct from the factory on volume tiers. Bulk production usually takes four to six weeks from sample approval, shipped DDP with export paperwork and HS codes handled. See how OEM & private label works →

Frequently Asked Questions
What is a Sinskey hook used for?
Rotating and positioning an intraocular lens in the capsular bag, and manipulating the nucleus during phacoemulsification.
What tip angle should we stock?
90-degree tips engage the optic positioning hole more positively; 45-degree tips are gentler. Both are commonly stocked.
Why does tip radius matter?
It must engage a positioning hole without marking the lens optic or catching the posterior capsule — a balance set by the tip radius.
Can you manufacture these under our own brand?
Yes — full OEM and private label. We laser-mark your logo and catalog numbers, pack in your branded boxes, and work from your drawings, tech pack or a reference sample, with a pre-production sample approved before any bulk run.
