Abstract
A small gauge surgical instrument is shown with advantages such as diminished “play” at the tip. A surgical instrument assembly is also shown with support along a length of the instrument that can be selected by the surgeon. Devices and method described provide adjustability of the instrument without protruding into a gripping surface of the instrument.

An ophthalmologic instrument, comprising:
- a base unit having an outer surface lateral to a longitudinal axis, with no protrusions or controls on the outer surface lateral to the longitudinal axis of the base unit;
- a small diameter instrument fixed in relation to the base unit, and extending from the base unit, the small diameter instrument having a length;
- a support frame slidably coupled to the small diameter instrument along the length;
- an adjustment mechanism for the support frame, to provide two or more different levels of lateral support to the small diameter instrument, wherein the adjustment mechanism is located on a surface other than the outer surface lateral to the longitudinal axis of the base unit;
- and
- wherein the support frame is spaced laterally apart from the small diameter instrument, and contained within the outer surface lateral to the longitudinal axis.
