The Authors missed out a previous study on a similar topic. The additional reference is listed below as reference 1, and should appear in the text as below.
In the Discussion section,
“Tear glucose measurement has been suggested as a potential, noninvasive strategy of blood glucose prediction8,10,32. Most of the previous studies focused on developing sensors with a higher accuracy since the glucose concentration in tears is known to be lower than that in the blood13,33,34. However, to our knowledge, studies on devices for practical, self-diagnostic applications is scarce. In this context, a device allowing concurrent tear collection and glucose measurement could be useful and convenient for users. Such a device would be more advantageous if the measurement could be reliable even with a small quantity of tear fluid as this would allow for a short time of tear collection, hence less invasiveness on the preocular tissues.
Therefore, we proposed the tear-glucose device herein as a noninvasive self-diagnostic tool for prediction of blood glucose levels.”

Most of the previous studies focused on developing sensors with a higher accuracy since the glucose concentration in tears is known to be lower than that in the blood13,33,34. A previous paper by Kownacka et al.1 reported results of phase II clinical trial for a device for continuous glucose monitoring in tear fluid, which needs to reside at the preocular surface while being wired to the reader. However, a device allowing sampled tear collection and glucose measurement could be also useful and probably more convenient for users. Such a device would be more advantageous if the measurement could be reliable even with a small quantity of tear fluid as this would allow for a short time of device contact for tear collection, hence less invasiveness on the preocular tissues.
Therefore, we proposed the tear-glucose device herein as an alternative noninvasive self-diagnostic tool for prediction of blood glucose levels.”
