The purpose of this study is to Evaluate the efficacy and longevity of a Human-derived, non-cadaveric, acellular dermal implant (BellaDerm) as a posterior spacer graft in the correction of lower eyelid retraction, taking into consideration issues associated with the use of acelular dermis such as contraction and potential regression of repairs.
