Intraocular suture retrieval with a hook

 A pig-tail hook is used to retrieve a suture via the paracentesis incision. |
In many of the cases that I've presented here in the past year, we've used intraocular suturing to repair a damaged iris or to securely fixate an IOL in the eye. These cases can be technically challenging, especially the retrieval of sutures from the anterior chamber and their delivery outside the eye through a sub-1-mm paracentesis incision. For a typical case of an iris-fixated IOL, this has to be done six to eight times.
In order to simplify suture retrieval, I designed a simple instrument: a micro-hook that looks like a pig tail. This allows the surgeon to easily entrap the loose suture ends and manipulate them into position. This has greatly simplified the most tedious aspect of intraocular suturing and has made the surgeries more efficient.
The Devgan suture hook is available from Storz instruments. Dr Devgan has no financial interest in the sale of this instrument.
