Abstract
With good reason, no chair has only two legs; by the same logic, instruments should not be held with two fingers only. The VR surgeon must understand, if not intuitively then by learning, how to hold an intraocular instrument securely and efficiently. The actual operation of the tool, such as the grabbing of a membrane with a forceps, is best broken down into the particular elements of the movement to optimize the maneuver; finally, the surgeon must learn to overcome the unintentional reflex of continually squeezing the instruments, even when they are not actually operated.

The inexperienced surgeon tends to lift the forceps before or as the jaws are closing; consequently there is no purchase of the membrane. This, of course, is less of an error than closing it while the jaws are pushed down.
