External application of an irrigating lens loop for extracapsular cataract extraction.
A modified irrigating lens loop applied externally to the eye may be used to express the nucleus in an extracapsular cataract extraction. No skill is required in subluxating the nucleus into the anterior chamber, as this maneuver is not necessary. The danger of posterior capsule rupture is diminished because no counter-pressure is applied and the lens loop is not placed in the eye. It is occasionally necessary to peak the pupil with forceps if it is not well dilated. We recommend this technique to simplify extracapsular cataract extraction and to markedly reduce the surgeon's risk of rupturing the posterior capsule.
