Used in Descemet-stripping endothelial keratoplasty: a fine angled hook that scores and peels the recipient's Descemet membrane from the back of the cornea.

The article sold under this heading is a DSAEK stripper paddle, a fine double-ended ophthalmic hand instrument used in Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) and related corneal transplant procedures, to score and strip Descemet's membrane from the posterior cornea before the donor graft is placed. One end is an angled, reversed Terry-Sinskey hook, used to score the membrane and lift its edge. The other end is an angled, textured paddle, used to wipe the membrane free of the underlying stroma from the periphery toward the center. It is turned in one piece with no joint and no moving part, with a round handle knurled at each end for grip. This is a double-ended combination instrument, not the plain single-ended hook the article name alone suggests.

This is the steel each line is made from as standard. A different origin can be supplied on request (a lower grade in Japanese steel, for example), agreed on your order.

Premium is the line where the choice is yours: 420 or 440C, agreed on your order. Economy is always 410 and Executive is always 440C. Those three are the instrument steels. Hollowware and sterilization containers are made in AISI 202 on a Clinical order and AISI 304 on a Premium or Executive one, and they are not offered in the Economy line at all, which is the section above.

The five grades, side by side, and what each one is for

True of every order

Instruments are marked to the buyer's requirement (TGI, unmarked, or the buyer's own brand), agreed on the order.

Customized packaging is part of what TGI supplies. Your own printed boxes, your labels, your brand on the pack, or plain export packing, whichever your market needs. The packing for your order is agreed with you and confirmed on the order.

Manufactured under the quality management system covered by TGI's ISO 9001:2015 and ISO 13485:2016 certificates. Certificate numbers and the issuer's registry are on the certification page. Open the certificates

Every batch of steel is ordered to a specified grade and arrives with the mill's own certificate, which identifies the mill and states the grade. TGI checks the material at the factory against its own requirement before it goes into production. That check is TGI's own inspection, not an independent laboratory test.

TGI manufactures in its own factory in Sialkot and also supplies articles made by contracted partner workshops, to TGI's specification. Which applies to a given article is confirmed on your order.

One-year guarantee on Premium and Executive tier instruments, hollowware and sterilization containers: any technical manufacturing defect, including material faults and rust, is replaced free of charge. Damage from handling or accidents is not covered. The year runs from the day the goods leave Sialkot.

If something is wrong with a delivery (a manufacturing defect, or a short or wrong article), tell us on WhatsApp within 7 days of delivery, with a video and photographs of what arrived. Replacement instruments are sent free of charge and dispatched within 24 hours of us seeing them; you pay the shipping, and they reach you as a normal order does.

Damage that happened after the goods left Sialkot is a claim against your carrier. The video of your parcel at the shipping office is sent to you before shipment and is the evidence that claim needs.
