We thank the authors for their interest in our paper [1] and for pointing out inconsistencies in the manuscript. The published figures for the duration of retinal detachment in the treatment group were in fact the mean and standard deviation; the median and interquartile range have now been inserted, and it can be seen that the groups are well-matched. The total number of patients with grade B PVR has also been amended. A corrected table is provided in the next page.
