ABSTRACT

To compare the endothelial parameters and thickness profiles of endothelial keratoplasty (EK) lamellae from donated whole eyes post vitreous humour aspiration (VHA) with those prepared from their mate control eyes (without VHA). Between March 2019 and March 2020, a few steps were added when aspirating the vitreous humour and also before dissecting the corneal tissue with microkeratome. EK lamellae were prepared from whole eyes that underwent VHA and their corresponding endothelial and thickness profiles were compared with those prepared from their respective fellow control eyes. Post-operative data in terms of graft attachment and clarity and the rate of reoperation were also reviewed. 115 eyes that underwent VHA and 115 of their respective fellow eyes were enrolled. No significant difference was noted in the endothelial parameters between the two groups. Mean central thickness of the EK lamellae and increase of thickness towards the periphery were not significantly different between the groups. Both groups did not show a significant difference with respect to the anticipated dissection depth, post-operative graft clarity, graft attachment, and the rate of regraft. This study demonstrates that aspirating vitreous humour has no adverse effect on the endothelial and thickness profiles of the EK lamellae that are prepared from these donated whole eyes, once the specific steps outlined by the eye bank are adhered to when aspirating the vitreous humor before performing the microkeratome dissection. The success rate of the grafted lamellae was comparable between the study groups. More... »
