Lower eyelid retractionLower eyelid retraction is common and causes symptoms of ocular irritation and discomfort, as well as issues of cosmesis and facial asymmetry. Moreover, the ocular surface may suffer exposure damage. Prior eyelid surgery, a negative vector facial morphology, and thyroid eye diseaseThyroid eye disease are common conditions in which eyelid retraction is present. A spacer graftSpacer graft to the posterior lamella aims to elevate the eyelid margin. Many materials have been used in this context. Hard palate grafts shine due to their similarity to native tarsal tissue with respect to consistency, thickness, stiffness, and the presence of a mucosal surface.
