—In reading the article in the Archives by Sugar et al (96:446-448,1978), I was struck by the remarkably similar results obtained in a study that I engaged in.In a retrospective study of nine patients in whom one eye had a cataract extraction by the phacoemulsification technique, a comparison was made of the endothelial cell density of the operated eye and the fellow unoperated eye. The result, reported at an in-house research meeting at the Jules Stein Eye Institute in June 1977, was of an average cell difference of 28% fewer cells in the operated eye. This closely compares with the 33.8% difference reported by Sugar et al. Furthermore, there was no substantial difference between procedures performed by house staff or faculty.I became aware, via personal communication, of notably lower cell loss found by others. Sugar et al similarly note wide discrepancies between their study and
