ABSTRACT

Ocular prosthesis retention may be poor in the setting of lower eyelid
retraction and loss of eyelid ligamentous support. Lateral canthoplasty alone
is often insufficient. We report a surgical technique and describe outcomes
with the novel use of an acellular dermal collagen-matrix graft fixated
to the lateral orbital rim. The series included six patients with lower eyelid
malposition and poor prosthesis retention who had failed previous surgical
