EVERY physician is periodically called upon to remove foreign bodies from the eye. A piece of cotton wrapped around a wooden swab is most frequently used to remove the particle.
Figure 1A shows a cotton swab under the low-power magnification of the microscope. The rough, irregular projections will increase the irritation of the optic membrane. Figure 1B shows a freshly laundered handkerchief under the low-power magnification of the microscope. The sharp, irregular projections will add to the irritation of an already irritated membrane. To overcome these objections, 1 experimented with a variety of substances and found that a specially smoothened round-wire loop caused the least amount of irritation.
Figure 1C shows the specially smoothened round-wire loop under the low-power magnification of the microscope. The perfectly smooth wire surface causes the minimal irritation to the sensitive ocular membrane. An eye-particle remover incorporating this smoothened round wire was described
