—Olson and Brodstein1 recently reported encroachment of the polypropylene (Prolene) haptics of a posterior chamber intraocular lens on the visual axis of a patient. They stated that the condition had not affected the patient's visual acuity, but "patients often complain of visual disturbances or a dramatic reduction of vision caused by IOL loops encroaching on the pupillary space." I have had the opportunity to examine five patients who had the same condition described by Olson and Brodstein, and none of these patients had any symptoms either. Frankly, I would not have expected any symptoms since the opaque polypropylene haptics obstruct only a small percentage of the light rays entering the pupil, and as such are analogous to one or two anterior or posterior cortical spoke opacities, which also have no effect on patients who have these lesions in their crystalline lenses.The situation might be different,
