AbstractExposure keratopathy may result in ocular surface dryness, pain, corneal ulceration and loss of vision. Upper eyelid loading is an effective surgical treatment for paralytic lagophthalmos but has been criticised for complications of implant exposure and poor cosmesis. We therefore reviewed the safety and efficacy of our technique of upper eyelid post-septal loading for exposure keratopathy in this context. A retrospective case notes analysis was undertaken of 38 patients who had upper eyelid loading, all with post-septal weight placement, for correction of lagophthalmos. Patient demographics, indications for surgery, outcomes and complications were analysed. The mean age of all patients was 59.6 years. Exposure keratopathy was secondary to facial nerve paralysis in all but two patients, with tumor excision being the commonest underlying aetiology (63.8%). The mean implant weight used was 1.4 grams. Pre-operatively, all 38 patients had ocular discomfort despite maximal use of lubricating eye drops but post-operatively, 29 patients (76.3%) were comfortable without any such drops. Mean lagophthalmos on blink and gentle closure improved from 7.42mm and 5.47mm pre-operatively to 2.18mm and 1.18mm post-operatively (p < 0.001). Similarly, before surgery all patients had some corneal staining but after surgery 37 patients (97.4%) had none. The gold weight was removed in four patients (10.5%), due to chronic inflammation in three and due to mild astigmatism in one. No patient had exposure of the weight and one patient had a ptosis repair 6 months after surgery. Upper eyelid loading was effective in reducing both signs and symptoms of exposure keratopathy related to lagophthalmos in our series. Patients were very satisfied with the surgical outcome and complications related to exposure and cosmesis were very rare.
