Double-pointed 30-gauge needle for keratocentesis.
A new, efficient instrument for performing keratocentesis for aqueous humour aspiration and anterior chamber microinfusion is described. It consists of a double-pointed 30-gauge needle, a liquid container (a nonflexible vinyl tube plugged at one end with a rubber stopper) and a aspiration-infusion syringe connected to the container and needle by a flexible vinyl tube. The instrument's advantages are a safer technique, complete collection of the aqueous humour and better handling of the sample.
