## Indications for use
Labtician Lid Load External Eyelid Sizing Weights are used by the physician to determine the correct gold eyelid weight to be implanted in the treatment of lagophthalmos. Labtician Lid Load External Eyelid Sizing Weights are used by the physician who affixes a succession of external eyelid weights to the outer surface of the eyelid using until the proper eyelid closure is attained. Because the levator muscle seems to strengthen after the weight is added, the optimal weight for implantation is ususally that which holds lid about 1.0 mm lower than the normal lid as the patient looks straight ahead. The corresponding implantable gold eyelid weight is then prescribed for implantation. Sizing weights are not designed to be implanted, and are provided non-stetile and are re-usable following cleaning with soap and water and/or alcohol and rinsing with tap water.
