We read with interest the recent paper by Arora and associates evaluating the outcomes of deep anterior lamellar keratoplasty (DALK) in children with advanced keratoconus. We commend the authors for carrying out an excellent study.
While the study is indeed interesting, there are certain points we wish to highlight. Firstly, there is discrepancy in the number of patients as mentioned in the abstract. At one place “A retrospective analysis was conducted of 20 eyes of 16 patients” and another place “At the final follow-up, 18 patients had clear grafts in the visual axis area.” Are these 18 eyes of 16 patients who had clear graft? Secondly, the mean thinnest pachymetry of the patients was 334.2 μm. What was the standard deviation of mean thinnest pachymetry? Thirdly, in the present study, low-potency steroids were continued even after suture removal at 6–9 months. For how long were they continued? Could cyclosporine drops have been substituted instead of these steroids to decrease vascularization?
