DM and wound healing. Poorly controlled diabetes can adversely affect would healing. Diabetic patients who have undergone surgery must have close glucose monitoring and control to get the best results. This would be the connection of diabetes with keratoplasty, which is a surgical procedure.
↑ed Complications. Diabetes mellitus = elevated blood (& extracellular) glucose. Glucose permeates the cornea & binds water, the cornea becomes edematous, more prone to infection & poor healing. Keratoplasty is a surgical procedure promoted for a variety of purposes. For those with dm, because of the underlying corneal problems, this is an inherently higher risk of poor outcomes.
