RESUMEN
A modified tip for the Bronson intraocular electromagnet has been developed. The tip was machined to a 20-gauge cylinder that can be inserted readily into the eye either through an entrance wound or through a pars plana incision. Placement of the tip of the magnet inside the eye allows the foreign body to impact the tip of the magnet rather than the wall of the eye.

We describe a quick and effective technique for performing safe anterior chamber paracenteses. The technique consists simply of inserting a small gauge disposable hypodermic needle without an attached syringe into the anterior chamber. The intraocular pressure and capillary action of the needle readily cause the rapid drainage of aqueous humor. This technique eliminates the cumbersome manipulations and potential complications associated with using an attached syringe for aspiration.
