Viscoelastic materials possess a unique set of properties that result from their chemical structure. These properties enable them to protect the corneal endothelium and epithelium from mechanical trauma and to maintain an intraocular space, such as the anterior or vitreous chambers, even in the face of an open incision. Hence viscoelastic materials have been successfully applied to many areas of ophthalmic surgery, most notably anterior segment surgery, with few complications. There are currently three commercially available viscoelastic preparations, and several new preparations are in various stages of development.
粘弹性材料具有一系列因其化学结构而产生的独特特性。这些特性使它们能够保护角膜内皮和上皮免受机械损伤，并即使在有开放切口的情况下也能维持眼内空间，如前房或玻璃体腔。因此，粘弹性材料已成功应用于眼科手术的许多领域，最显著的是前段手术，且并发症很少。目前有三种市售的粘弹性制剂，还有几种新制剂正处于不同的研发阶段。
