Purpose

To evaluate the efficacy of sutureless amniotic membrane transplantation using a soft bioavailable ring in the management of ocular surface disorders.

Methods

We present a modified technique using a soft, special designed bioavailable ring set (Amnioring) for sutureless amniotic membrane fixation to the ocular surface. A fresh amniotic membrane with a diameter greater than the outside diameter of the ring was folded inwardly over the ring such that the inner side of the ring was covered with the amniotic membrane. The ring was inserted onto the ocular surface.

Results

The ring was inserted in 4 eyes of 4 consecutive patients with ocular surface disorders. The mean total operating time was 3 min. The ring fixated the amniotic membrane to the bulbar conjunctiva and provided a quick and easy sutureless placement of amniotic membrane. In all cases, pain was significantly relieved. The corneal epithelial defect and inflammation were markedly reduced.

Conclusions

This novel ring designed for sutureless placement of amniotic membrane provided very good anatomic and functional outcomes in patients with ocular surface disorders. It is less invasive, less time consuming and allows placement in the office conditions with low cost.

用软环无缝固定羊膜治疗眼表疾病

目的

评估使用软生物可利用环进行无缝线羊膜移植治疗眼表疾病的疗效。

方法

我们提出了一种使用柔软、特殊设计的生物可利用环组 (Amnioring) 的改良技术，用于将羊膜无缝固定到眼表。将直径大于环外径的新鲜羊膜向内折叠在环上，使得环的内侧被羊膜覆盖。将环插入眼表。

结果

该环被插入连续 4 名患有眼表疾病的患者的 4 只眼睛中。平均总操作时间为 3 分钟。该环将羊膜固定在球结膜上，并提供了快速简便的羊膜无缝线放置。在所有情况下，疼痛都得到了显着缓解。角膜上皮缺损和炎症明显减少。

结论

这种新型环设计用于羊膜的无缝放置，为眼表疾病患者提供了非常好的解剖和功能结果。它侵入性更小，耗时更少，并且允许以低成本放置在办公室条件下。
