When the incision of the sclera, suprachoroidea and choroidea is performed under the microscope step by step, the release of subretinal fluid becomes an absolutely controlled microsurgical procedure. When employing this technique, one can avoid complications related to the injury of choroidal vessels, especially if one uses transillumination with fibre-optics during the perforation of the choroid. A further useful tool for drainage is a sclerotomy retractor which allows the spreading out the edges of the sclerotomy--wound by grasping the loops and pulling them aside of a pre-placed Mendoza suture. As the retractor does not engage the sclera directly but only with the aid of the pre-placed suture, it is possible to observe the operation field without any hindrance from the instrument and to perform microsurgical incision of the chroid at any desired point.
当在显微镜下逐步进行巩膜、脉络膜上腔和脉络膜切口时，视网膜下液的引流就成为一种完全可控的显微手术操作。采用这种技术时，可以避免与脉络膜血管损伤相关的并发症，特别是在脉络膜穿孔时使用光纤透照的情况下。另一种有用的引流工具是巩膜切开牵开器，它通过抓住预先放置的门多萨缝线的线环并将其拉到一旁，使巩膜切开伤口的边缘展开。由于牵开器不直接接触巩膜，而是仅借助预先放置的缝线，因此可以毫无阻碍地观察手术视野，并在任何所需位置进行脉络膜的显微手术切口。
