Glaucoma drainage device (GDD) implantation in the anterior chamber are associated with corneal complications. We describe a novel technique to implant GDD tubes in the posterior chamber of pseudophakic eyes.
Ten patients with glaucoma who required GDD tube implantation were included.
The new technique begins with the passage of one of two straight needles existing at each end of a 10-0 Polypropylene suture through the GDD tube. A 23-gauge needle then is inserted at an angle 180° away and passed from the anterior to the posterior chamber and finally through the sclera. The two suture straight needles from the 10-0 Polypropylene suture are positioned in the lumen of the 23-gauge needle. The 23-gauge needle is then extracted from the eye by passing the 2 needles through the lumen. The suture remains inside the posterior chamber, and the tube is inserted into the posterior chamber by pulling on the suture from the other side. No intra-operative complications were found such as bleeding, vitreous tube placement, bent tubes, etc. CONCLUSIONS: This surgical procedure to implant a tube into the posterior chamber of the pseudophakic eyes is uncomplicated and facilitates the insertion of the flexible tube into the posterior chamber. This eliminates the tendency of the tube to enter the vitreous as the tube is always placed in the posterior chamber away from the cornea.

在前房植入青光眼引流装置（GDD）与角膜并发症有关。我们描述了一种在人工晶状体眼后房植入 GDD 管的新技术。
纳入 10 例需要 GDD 管植入的青光眼患者。
新技术开始时，将两根 10-0 聚丙烯缝线的两端各穿过一根直针穿过 GDD 管。然后以 180°的角度插入 23 号针头，从前房穿过至后房，最后穿过巩膜。两根 10-0 聚丙烯缝线的直针从 23 号针头的内腔穿过。然后将 23 号针头从眼睛中抽出，通过将两根针穿过内腔。缝线留在后房内，通过从另一侧拉动缝线将管子插入后房。术中未发现出血、玻璃体管放置、弯曲管等并发症。
这种将管子植入人工晶状体眼后房的手术程序并不复杂，便于将柔性管子插入后房。这消除了管子进入玻璃体的趋势，因为管子始终放置在后房远离角膜。
