The authors refer about primary development of elastic and sufficiently strong device, which due to its spherical shape bandages the conjunctival space of the palpebral fissure and is used to form the inferior and superior cul-de-sac. It is made from a silicone mixture for medical use - Silastic Medical Grade Elastomer. Its layer in the shape of spherical cap of outer diameter 24.4 mm, height 8.5 mm; the layer thickness is 0.5 mm. Its advantage is the oxygen permeability.
The spherical covering foil was applied as an arrangement before keratoplasty in four adult men to form fornices after relieving of symblephara reaching the cornea caused by alkali (lime) burn (in three of them) and after liquid aluminium burn (thermal injury). In five years old boy, the spherical covering foil helped to form the palpebral fissure and to improve the eye motility; the symblepharon was related to the inborn coloboma of the upper eyelid. To prevent the symblepharon appearance, the spherical covering foil was used in an adult man after molten polypropylene burn and in an eight years old boy with Stevens - Johnson syndrome.
The spherical covering foil is used for cul-de-sac forming after relieving of the symblepharon or to prevent its appearance after the eye burn.
作者提及了一种弹性且足够坚固的装置的初步研发,该装置因其球形形状可包扎睑裂的结膜间隙,并用于形成下穹窿和上穹窿。它由医用硅酮混合物——医用级硅橡胶制成。其呈外径24.4毫米、高度8.5毫米的球冠形状的层;层厚度为0.5毫米。其优点是具有透氧性。
在4名成年男性角膜移植术前,将球形覆盖箔作为一种装置应用,用于在解除由碱(石灰)烧伤(其中3例)和液态铝烧伤(热损伤)导致的累及角膜的睑球粘连后形成穹窿。在一名5岁男孩中,球形覆盖箔有助于形成睑裂并改善眼球运动;睑球粘连与先天性上睑缺损有关。为防止睑球粘连出现,在一名成年男性发生熔融聚丙烯烧伤后以及一名患有史蒂文斯 - 约翰逊综合征的8岁男孩中使用了球形覆盖箔。
球形覆盖箔用于解除睑球粘连后形成穹窿或在眼部烧伤后防止其出现。
