Facial nerve palsy is impairing orbicular muscle function leading to lagophthalmos. This disease impairs patients' quality of life by exposure keratopathy which is accompanied by ocular pain and deteriorate visual acuity at a variable degree. The paper's aim is to show up the place of lagophthalmos in anterior ocular segment pathology and to evidence the results obtained by us with a new therapeutical method applied in several cases. All cases with lagophthalmos have ocular complications like exposure kerato-conjunctivitis. The treatment was both conservative and surgical which consisted in majority of cases in blepharoraphy with its inconveniencies, aesthetical and functional. We have applied a new surgical method--gold weight superior lid implantation--in 4 cases and the results are promising.
