The use of the gold weight is an established procedure in the treatment of lagophthalmos and usually produces successful results. The critical technical issues are the firm suture fixation to the tarsal plate and the high location of the weight on this plate. However, the estimated weight of the implant from the trials on the skin of the upper lid fails to obtain the expected eye closure outcomes after surgical implantation on the tarsal plate. One of the main reasons could be the different curvature on the skin and on the tarsal plate of the upper eyelid. In this study, the angles between the vertical line and the surface of the outer (skin) and inner (tarsal plate) part of the upper eyelid have been analyzed when the eye is opened and closed. The results show that an addition of 0.2 g to the gold weight estimated in the trial is required to achieve a similar closure of the eye by means of the gold implant on the tarsal plate.
使用金片是治疗兔眼症的既定方法，通常会取得成功。关键的技术问题是将其牢固缝合固定在睑板上以及金片在该板上的高位放置。然而，在上眼睑皮肤上进行试验估算出的植入物重量，在手术植入睑板后未能获得预期的闭眼效果。主要原因之一可能是上眼睑皮肤和睑板的曲率不同。在本研究中，分析了睁眼和闭眼时上眼睑外侧（皮肤）和内侧（睑板）部分表面与垂直线之间的角度。结果表明，为了通过睑板上的金植入物实现类似的闭眼效果，需要在试验估算的金片重量上增加0.2克。
