Purpose: To describe a technique to treat paralytic lagophthalmos and exposure keratitis with gold weight implants covered by levator aponeurosis.
Methods: The authors studied a case series of 29 patients who underwent surgical treatment for paralytic lagophthalmos using the technique of gold weight implantation covered by the aponeurosis of the levator palpebrae superioris muscle between June 1997 and December 2006. None had undergone previous surgical treatment.
Results: All patients sustained their implants; there were no cases of extrusion, dislocation, or infection. Patients had significant improvement of symptoms, especially exposure keratopathy, with lagophthalmos dimensions decreased from 4 to 5 mm preoperatively to 0.5 mm after surgery.
Conclusions: Excellent results were obtained by recessing the levator palpebrae superioris muscle aponeurosis with relaxing incisions and advancing it to overly the gold weight implant completely. Visibility of the implant in the pretarsal upper eyelid surface was minimized, extrusion was avoided, and good eyelid position was obtained.
