We observed surface finishing of 18 manufacturers' intraocular lenses using non-contact specular microscopy and scanning electron microscopy. Many lenses showed apparent surface particulates or particles, contaminated liquid adhesion, scratches, dimples or a water ring-like patterns, and irregular haptic and/or positioning hole edges. The results of specular microscopy indicating poor surface finish in many lenses, did not agree with the scanning electron microscopy results. This suggested that specular microscopy is more useful for surface quality studies than conventional scanning electron microscopic observation.
