When practicing intraocular maneuvers it is important to get the sensation of working through limited space (like the scleral tunnel) where you will be able to execute a limited range of movements with your hand and your forceps.
To practice these movements, you may cut out a cup of a quail eggs box, cut off a the bottom (to allow visualization) and a thin rectangle through which the Utrata forceps will get in, and fix it with pins to a styrofoam head or plaque.
You will be able to practice the capsulorrhexis on a grape or tomato, nuclear rotation, IOL insertion, etc.
