—The report by Dr. Scheie et al (Arch Ophthalmol 89:293-295, 1973), in which they show the prevalence of retinal detachment in a large consecutive series of lens extractions to be 2.2%, is certainly a valuable addition to the English literature. Their data, in comparison with other reports in the literature, certainly do suggest that there is a no increased incidence of retinal detachment following the use of alphachymotrypsin. However, only a control study will determine this.If the authors have the available data, it would be useful to know in how many of the aphakic detachments was an intracapsular extraction performed and in how many was an extracapsular extraction performed. The incidence of vitreous loss in each group would also be valuable information. It would certainly be interesting to have a table relating the length of time at which the retinal detachment was diagnosed following the lens
