By scanning electron microscopy, we studied eight lenses from eyes that had
received a neodymium-YAG laser iridotomy one day prior to elective
intracapsular cataract extraction. In some of these cases, pitting lesions
were found on the anterior-equatorial lens surface, thereby showing that
lenticular damage may occur following this procedure if the iridotomy is
applied too centrally. It is recommended that care be taken to ensure that
the iridotomy be placed at a site peripheral to the outer circumference of
the lens.
