Abstract

Microcannulas used during vitreous surgery protect the entry site, avoid vitreous base damage, and allow easy exchange of 20- and 19-gauge (0.9- and 1-mm) instruments. The use of three cannulas of equal size permits interchangeability of all instruments. A locking mechanism allows attachment and exchange of various infusion lines (balanced salt solution, gas, and oil). Temporary plugging of the cannula is possible. Selection of 1 mm as a standard diameter for all cannulas make multiple-function instruments feasible.
