Steinberg et al1 reported that specular microscopy was more commonly performed by ophthalmologists who also performed more than 200 cataract extractions per year, operated in a private office or in a freestanding ambulatory surgical center, and had published an article relevant to cataract surgery. They questioned the cause of the association of these professional characteristics with increased use of this test. On this subject, I would like to offer the following thoughts.
There is likely to be a positive association between the volume of cataract extractions that a surgeon performs per year and the location at which he or she performs them (they are more likely to be performed in an ambulatory surgical center), and of course, an ophthalmologist who has a relatively large surgical volume is much more likely to publish an article concerning his or her experience. It is also not surprising that these ophthalmologists would be
