Paired parallel locking forceps.

We describe an instrument used to prevent contact between an antimetabolite and the conjunctiva-Tenon's wound edge in filtering surgery. Paired parallel locking forceps were used to keep the everted conjunctival-Tenon's wound edge from touching the antimetabolite sponge during limbal-based filtering surgery while enabling manipulation of the antimetabolite sponge. This allows the surgeon to more easily avoid the conjunctival edge, making antimetabolite touch easier and safer.

Refractive keratotomy using a footplateless knife.

This article describes a diamond knife designed for safer, more precise extension of pre-existing refractive keratotomy incisions. The knife has a blade with a sharp vertical cutting edge whose progress is limited by a dull safety stop. The stop prevents extension of a wound by more than 500 microns at one time, minimizing the possibility of overextending the keratotomy incision into the optical zone. Because it requires no footplate, the knife improves visibility, allowing for more precise surgery.
